The room does more to the sound than the equipment does, which is the opposite of how most households approach this. A capable system in a bare room with a tiled floor, large glazed areas and hard plastered walls will sound harsh and muddled, while a modest system in a carpeted room with soft furnishings and curtains will sound considerably better for a fraction of the outlay. Speaker placement and where people actually sit matter almost as much, and both are free to get right. The other decision that cannot be undone is the cabling, because running speaker cable and data through open wall framing during a build or a renovation costs a few hundred dollars while retrofitting the same runs through finished double brick is a different job entirely. Two more decisions cost nothing and matter enormously. Put the screen at eye level when seated, because a television mounted above a fireplace forces everybody to look upward for a whole film and it is the most common regret households report in this trade. And work out where people actually sit before anything is mounted, since screen height, speaker angle and subwoofer position all refer back to that one point in the room and a system arranged around where the furniture happened to be helps nobody.

Why the Room Beats the Equipment
Sound reaching your ears arrives as a mixture of what comes directly from the speakers and what arrives a fraction later after bouncing off surfaces. In a room full of hard surfaces those reflections are strong and closely spaced, which smears detail and makes dialogue harder to follow.
That is why the same system sounds quite different in two rooms. A modern open plan living area with polished concrete or tile, large windows and minimal soft furnishing is acoustically the hardest environment available, and it describes a great many newer South Australian homes.
The encouraging part is how cheap the fixes are relative to equipment. A rug on a hard floor, curtains rather than blinds on the largest window, a bookshelf on a bare reflective wall and furniture that breaks up flat surfaces all reduce reflections meaningfully and cost nothing beyond what a household might furnish with anyway. Doing those first and then listening is a better sequence than buying larger speakers to overcome a room that was never going to cooperate.
Cabling, and the Window That Closes
Running cable through open framing is the cheapest work on this page and the only part that cannot be revisited later. A renovation or a new build with the walls open is the moment, and households who miss it pay several times over afterwards. Moving a chair costs nothing. Sit first, buy second. Sit down in the room and look at it first. Anybody quoting this work will have an opinion about the room, and the useful ones share it before they price the equipment.
The room itself decides most of the outcome here. A room assessed properly before anything is ordered produces a system the household is still happy with several years later, and one assessed afterwards produces a list of things that cannot now be changed. Households rarely regret that one. Ten minutes spent in the actual viewing chair working out where the screen and the speakers should sit will shape the result more than the next several thousand dollars of equipment ever could. Installers take different views on how much this matters. When quotes differ widely, cable routing and making good usually explain the gap rather than the hardware specified.
Run more than you think you need. Additional speaker cable and data runs cost very little while the framing is exposed, and a spare run terminated behind a wall plate is worth having when something changes. A bare room sounds harsh. Walls dictate the method. A household that spends ten minutes in the actual seating position working out where the screen should sit and where the speakers would need to go has already made the decisions that will determine whether they are satisfied in two years. Installers who have set up rooms across Adelaide for years tend to ask about the floor covering and the window treatments before they ask about the budget.
Installers vary in how they raise this at quoting stage. Contractors who arrive, sit in the chair and look at the wall before quoting are doing the part of the job that decides the outcome. It costs nothing to check. Solid double brick in an older Adelaide home and framed brick veneer in a newer one present entirely different problems for mounting a screen and getting a cable from one side of the room to the other. Raising it at enquiry stage saves a longer conversation later. The equipment can always be upgraded later, where the cable route and the screen position are fixed the moment the plasterboard goes back on.
Conduit beats bare cable wherever it can be used. A draw string in conduit lets a future cable be pulled through without opening anything, which makes the installation adaptable and not fixed. The installer should be asked about it. The framing closes once. Two households buying identical systems will get quite different results depending on whether the floor is carpeted, whether the windows carry curtains or blinds, and whether anything in the room breaks up the flat reflective surfaces. The households who report the best results are almost never the ones who spent the most on hardware.
Installers who do this weekly will raise the point unprompted. Anybody installing these across Adelaide for years will have seen the same room problems repeatedly and can usually predict the result from a photograph of the space. Every additional speaker cable, data run and spare conduit put in while the walls are open costs almost nothing, and each one becomes a patching job and a painting job the moment the plasterboard goes on. Mentioning it at enquiry stage produces a clearer comparison of quotes.
Keep signal cable away from power cable. Running them together produces interference, and AS/NZS 3000 sets separation requirements for how the two are installed relative to each other. Hard rooms fight the system. Settle where the equipment will live before any cable is pulled.
Every run terminates somewhere, and moving the cabinet from one side of the room to the other after plastering is not a small change. Running the network side is covered at data and communications cabling. Polished concrete, tiled floors, large glazed openings and minimal soft furnishing describe a great many newer South Australian homes and also describe the most difficult acoustic environment an installer can be handed. Most will talk it through on site if asked.
Retrofitting is possible and it is a different cost. Cavity brick walls, insulated ceilings and double storey layouts all make cable routing slower, and some runs end up in surface mounted trunking. Fixings follow the wall. Photograph the open walls before the plasterboard goes on over them.
Knowing where cables and noggins sit makes every future job easier and costs nothing at the time. Sheeting and making good afterwards are covered at plasterboard installation. A mount rated for timber framing is not a mount for solid double brick, and a heavy articulating arm on plasterboard anchors is a screen waiting to come off the wall in front of everybody. Approaches differ noticeably between contractors, so ask more than one.
| Stage | Cabling Cost | What Is Possible |
|---|---|---|
| During construction | $600 - $2,000 per room | Anything, framing is open |
| During a renovation | Similar, if walls are open | Most things |
| Retrofit, plasterboard walls | Moderate | Achievable with patching |
| Retrofit, double brick | Higher | Often surface trunking |
| Through an accessible ceiling | Moderate | In ceiling speakers practical |
| Two storey, between floors | Highest | Route needs working out first |
Where the Speakers and the Seats Go
Start from where people actually sit and not from where the furniture currently is. The seating position is the reference point for everything else, and a system optimised for an empty spot in the room helps nobody. Cabling is a one time chance. Front left and right speakers work best at roughly ear height when seated, whether they are Krix, Bose or anything else. Mounting them high on a wall because it looks tidier sends the sound above the listeners, which is a common and entirely avoidable compromise.
Most of the dialogue comes through the centre speaker, which deserves attention. Placing it directly above or below the screen and angled toward the seating is what makes speech intelligible. Speaker cable and data pulled through open framing during a renovation costs a few hundred dollars, while the same runs chased into finished double brick afterwards become a considerably larger and messier proposition. A walk through the room settles it faster than any phone call. The disappointment surfaces months later rather than on installation day, when a household realises the system they paid for is fighting a room nobody assessed.
Surround speakers belong beside or slightly behind the seating and not at the front. Households frequently place them too far forward because that is where the cable was run, which defeats the point. Moving the subwoofer changes the bass more than any setting does. Corners reinforce bass and can make it boomy, and moving the subwoofer a metre is often the difference between muddy and tight. On a double brick property the cable route needs settling before anything is ordered, since the answer usually runs through the ceiling and down rather than inside the wall.
In ceiling speakers, made by Adelaide manufacturer Krix among others, suit whole room listening and not critical viewing. They are discreet and convenient, and they fire downward and not at the listener, which is a trade off worth understanding. Seating sets the geometry. Cutting and making good is covered at ceiling repairs. Screen height matters at least as much as screen size does.
A television mounted above a fireplace forces everybody to look upward for hours, which is uncomfortable and the single most common regret in this trade. Getting the screen on the wall is covered at TV wall mounting. Everything from screen height to speaker angle refers back to where people actually sit, and a system arranged around where the furniture happened to be when the installer arrived is optimised for nobody in particular. Households who mention it at enquiry get a more accurate quote. Where a household is renovating anyway, this is the cheapest it will ever be and the only moment when every future option stays open.
| Element | Where It Belongs | Common Mistake |
|---|---|---|
| Front left and right | Ear height when seated | Mounted high for tidiness |
| Centre speaker | Above or below the screen | Buried inside joinery |
| Surrounds | Beside or behind the seating | Too far forward |
| Subwoofer | Wherever it sounds best | Jammed in a corner |
| Screen | Eye level when seated | Above the fireplace |
| Equipment | Ventilated, reachable | Sealed cabinet, no airflow |
South Australian Wall Construction and What It Allows
What the walls are made of decides how a television gets mounted, how cable gets routed and whether in wall speakers are possible at all. South Australian housing spans several constructions and each behaves differently.
Double brick is common in older Adelaide housing and it is solid all the way through, which means a television mounts securely into masonry with the right fixings but cable cannot be routed inside the wall without chasing into brick. Retrofits in these homes frequently end in surface mounted trunking or a route through the ceiling and down, and in wall speakers are generally not an option. Brick veneer, which describes a great deal of post war and modern stock, has a timber or steel framed internal wall behind the plasterboard, so cable routing is straightforward and in wall speakers are feasible, though the mount has to hit a stud instead of relying on plasterboard anchors for a heavy screen. Stone walls in the older inner suburbs behave like double brick with the added consideration that the stone may be soft and the mortar lime based, so fixings need care. Lath and plaster ceilings and walls in pre war homes are fragile and crack readily, which affects both cutting speaker openings and fixing anything substantial. Two practical points follow. Establish the wall type before ordering a mount, since the fixings differ entirely. And on a solid wall, plan the cable route through the ceiling early, because the alternative discovered late is trunking down a feature wall. Plaster repair sits at plasterboard installation and carpentry at carpentry services.
Mounting Into What You Actually Have
Establish the wall construction before buying a mount. Double brick, brick veneer, stone and plasterboard on steel framing each take different fixings and the wrong choice fails under load. Light control decides projectors. A large television on plasterboard needs to reach the studs. Anchors rated for the weight exist, and a screen cantilevered on an articulating arm applies considerably more load than a flat mount does.
Older stone and lime mortar walls need a considered approach. Fixings into soft stone or degraded mortar do not hold, and the position may need adjusting to find something sound. A room with west facing glazing and sheer curtains will wash out a projector image through most of an Adelaide afternoon, which turns an expensive installation into something the household only uses after dark. Two rooms of the same size can reach different answers here. A screen mounted at the wrong height cannot be fixed by any amount of equipment spending afterwards, which is why the position deserves more thought than the specification does.
In wall speakers need a cavity and a stud spacing that suits them. Measuring before ordering avoids discovering the chosen speaker does not fit between the studs. Ceiling mounted speakers need clearance above and insulation managed around them. A speaker packed tight with batts behaves differently from one with the specified back box or clearance. Managing batts around a speaker is covered at ceiling insulation.
Check for services before cutting anything. Wiring, pipework and ducting all run inside walls and ceilings, and a speaker opening cut into a cable is a bad day for everybody. Plan making good into the job. Retrofitting through finished surfaces means patching and painting, and a quote that ignores it is incomplete. Finishing the patched areas is covered at interior house painting.
Power, Data and Licensed Work
Get a dedicated outlet behind the screen rather than running a lead down the wall. It is tidier, it is safer and it is inexpensive while somebody is already doing the work. Electrical work needs a licensed electrician in South Australia, working to AS/NZS 3000, the wiring rules. Adding outlets, running new circuits and anything touching the fixed wiring are all licensed work rather than do it yourself territory. Adding outlets is covered at powerpoint and light switch installation.
Equipment draws more than households expect once it accumulates. An amplifier, a subwoofer, a projector, a console and network gear on one outlet is worth thinking about at installation. Placement beats upgrading. A wired network connection beats wireless for streaming at high bitrate. Running data cable to the equipment position during construction costs very little and removes a class of problem entirely.
Surge protection is worth including on a system of any value. The equipment represents real money and it sits permanently connected to both mains and antenna. Lowering the front speakers to ear height and moving the subwoofer a metre away from the corner will do more for the sound than replacing either of them with a more expensive model would. It separates a considered quote from a standard package. Installers who ask about the floor covering and the window treatments before quoting are assessing the thing that will decide whether the household is satisfied.
Antenna and aerial feeds still matter for broadcast television. A poor signal shows up as picture breakup that people wrongly blame on the new equipment. Aerial work is covered at antenna installation. Ask for the compliance certificate on any electrical component. It records that the work meets the wiring rules and it matters at sale. Broader wiring and circuit work sits at electrical services.
| Item | Why Include It | Cost |
|---|---|---|
| Outlet behind the screen | Removes the trailing lead | Part of $300 - $1,200 |
| Outlet at the equipment position | Everything plugs in locally | Same range |
| Wired network run | Beats wireless for streaming | Cheap during construction |
| Antenna feed | Broadcast picture quality | Varies |
| Surge protection | The equipment is worth real money | Separate item |
| Compliance certificate | Record of licensed work | Included |
Projectors, Ambient Light and the Adelaide Problem
A projector produces a picture by throwing light at a screen, so any other light in the room competes with it directly and the image washes out. That makes light control the deciding factor in whether a projector is the right choice, and it is where South Australian rooms often struggle. Adelaide has a great deal of bright daylight for much of the year, and modern local housing tends toward large glazed areas and open plan layouts, which is close to the worst case for a projector. A dedicated room with no external window, or one where blockout treatment genuinely excludes daylight, is where a projector delivers what people imagine. A living area with a west facing window and sheer curtains is not, and a household spending eight thousand dollars on a projector for that room will end up watching in the evening only and wishing they had bought a television. Several things follow for anybody considering one. Establish the light control first and price it honestly, since blockout blinds or curtains on large openings are a real cost and half measures do not work. Consider a large television instead, because screen sizes and prices have moved considerably and a bright panel handles ambient light in a way no projector does. Where a projector is the choice, throw distance, mounting height and a cable route to the ceiling position all need planning before anything is bought. And remember the room will be dark by design, which suits some households and not others. Blind and curtain work sits at blinds and curtain installation.
Open Plan Living, Which Describes Most New SA Homes
A great many South Australian homes built in recent decades put the kitchen, dining and living areas into one continuous space, and that layout creates specific difficulties for a home theatre that a separate lounge room does not. The space is acoustically large and irregular, which means reflections arrive from surfaces well away from the listening area and bass behaves unpredictably. Hard floors extend through the whole area and are rarely covered. Kitchen surfaces are reflective by necessity. And the seating position is usually fixed by the room's shape and not chosen for listening. Several responses work within those constraints. Define the listening area with a large rug instead of trying to treat the whole space, because the reflections that matter most are the ones near the seating. Accept that the surround speakers will be compromised by the layout and prioritise getting the front three right, because dialogue intelligibility from a well placed centre speaker does more for everyday viewing than rear channels do. Position the subwoofer by experiment and not by symmetry, as an irregular room has bass nulls in places a rectangular one does not. Consider a soundbar with a separate subwoofer as a genuinely sensible endpoint in this layout, since the compromises of the room limit what a full system can deliver anyway. And where the kitchen is within the same space, remember that a rangehood and a dishwasher both compete with the television at conversational volume. Flooring options sit at flooring.
Choosing Between a Projector and a Screen
Be honest about the room before committing to a projector. Light control does not refine this decision, it settles it, and a room that cannot be darkened is not a projector room. Large televisions from Samsung, LG and Sony have closed much of the gap. Screen sizes that once required projection are now available as panels, and a panel handles a lit room in a way projection cannot. Throw distance dictates where the projector can sit. A short throw unit mounts close to the screen while a long throw needs the room depth, and the cable route follows from that choice.
Screen type matters as much as the projector itself, and Australian maker Screen Technics publishes gain figures worth comparing. Gain, size and whether the surface rejects ambient light all affect the result, and a good projector on a bedsheet is a wasted purchase. Projector globes and lasers have finite life and a replacement cost. Factoring that into the comparison with a television is part of an honest assessment. Ceiling mounting needs both a fixing point and a power supply at that position. Neither is difficult during construction and both are awkward afterwards.
Calibration, Which Is Where Installed Becomes Working
Equipment mounted on a wall and plugged in differs from equipment set up properly, and the gap between the two is larger than households expect. A great many systems run for years in a state that delivers a fraction of what they cost.
Several settings account for most of it. Speaker distances and levels need entering so the receiver can align the output from positions that are not equidistant from the seating, and the automatic calibration routines built into most receivers do this reasonably well if anybody runs them. Speaker size settings determine what goes to the subwoofer and not to speakers that cannot reproduce it, and leaving everything set to full range is a common default that produces thin sound. Picture settings on a new television are generally configured for a showroom and not a living room, with brightness and colour pushed well beyond accurate, and selecting a cinema or filmmaker mode is usually a substantial improvement at no cost. Audio output format from a streaming device or console needs matching to what the system can decode, because a mismatch quietly drops the household back to stereo. And the source device settings matter as much as the receiver, because a player outputting the wrong format undoes everything downstream. A household should ask specifically whether setup and calibration are included in an installation quote, as some installers mount and connect while others configure the system and demonstrate it, and the price difference reflects genuinely different work.
Treating the Room Without Rebuilding It
Soft furnishing does most of the work at the lowest cost. Rugs, curtains, upholstered seating and even a full bookshelf all absorb and scatter reflections that a bare room sends straight back. The first reflection points are where treatment does most good. Those are the spots on the side walls and ceiling where sound bounces once between the speaker and the listener. Curtains beat blinds on a large window for sound as well as light. A heavy curtain with generous fullness absorbs far more than a flat blind does.
Hard floors contribute more than anything else in modern homes. A large rug between the speakers and the seating changes the character of a room immediately. Purpose made acoustic panels have their place and are rarely the first spend. They suit a dedicated room where the furnishing options have already been used.
Panel and treatment work sits at acoustic insulation. Containing sound within the room is a different problem from treating it. Stopping a home theatre disturbing the rest of the house needs construction and not furnishing. Isolating a room properly is covered at soundproof ceilings.
| Measure | Cost | Effect |
|---|---|---|
| Large rug on a hard floor | Furnishing | Substantial, do this first |
| Heavy curtains on glazing | Furnishing | Sound and light together |
| Upholstered seating | Furnishing | Meaningful |
| Bookshelf on a bare wall | Furnishing | Scatters reflections |
| Acoustic panels at reflection points | $500 - $3,000 | Targeted, for dedicated rooms |
| Construction for isolation | Substantial | Stops sound leaving the room |
Spending in Proportion, and the Honest Ranking
Households usually allocate their budget in roughly the reverse of the order that would produce the best result. Knowing the ranking beforehand tends to produce a better outcome for the same money.
Screen position and seating come first and are free, since a screen at eye level with the seating at a sensible distance transforms the experience and costs nothing but a decision. Room treatment through furnishing comes second and is also close to free, because rugs, curtains and soft seating are things most households buy anyway and choosing them with the room in mind costs no more. Speaker placement is third, and moving a subwoofer or lowering front speakers to ear height delivers more than upgrading them would. A capable soundbar with a subwoofer is fourth and represents the point where most households should stop, because the step from television speakers to a decent soundbar is enormous while the step from there to full surround is a refinement. Full surround with properly placed speakers is fifth and genuinely better for anybody who watches films seriously. Equipment beyond that point brings diminishing returns in an ordinary domestic room. The households who end up disappointed are generally those who spent heavily on electronics while leaving the screen above a fireplace, the floor bare and the speakers wherever the cable happened to reach. Lighting work sits at lighting installation.
| Ask Every Installer | Why It Matters | A Good Answer |
|---|---|---|
| Where will the cable run | Decides feasibility and cost | A described route, walked |
| What are my walls made of | Fixings and routing differ | Identified on site |
| Is making good included | Patching and painting add up | Stated either way |
| Who does the electrical work | Licensed work in SA | A licensed electrician, certificate issued |
| Will you set it up and calibrate | Installed is not configured | Included and explained |
| What happens about the room | It affects the result most | Raised without prompting |
Outdoor Areas, Alfrescos and Weather Rated Equipment
Adelaide's climate means a great deal of entertaining happens outdoors, and extending audio or a screen into an alfresco area is a common request that carries requirements ordinary indoor equipment does not meet. Weather rating comes first, because speakers and screens intended for outdoor use are built to tolerate moisture, temperature swings and ultraviolet exposure, and indoor equipment placed under a patio roof will fail sooner than an owner expects because humidity, dust and the temperature range under a roof in an Adelaide summer are all harsher than a living room. Direct sun defeats any screen, so a position that works in the evening may be unusable at four in the afternoon, and a screen rated for high brightness costs considerably more than an indoor panel of the same size. Electrical work outdoors carries its own requirements including weatherproof outlets and residual current protection, and it is licensed work. Sound carries further outdoors than households anticipate, which makes neighbour consideration a practical matter and not a courtesy, particularly on the smaller blocks common in newer estates. And cable routing to an outdoor area needs protecting from both weather and gardening. A household planning this during a build should include it in the cabling stage, since retrofitting a run to a detached alfresco is the same problem as any other retrofit. Outdoor electrical work sits at outdoor lighting and power.
Regional Considerations Across South Australia
Metropolitan Adelaide spans housing types that behave very differently. A double brick villa and a newer brick veneer home present quite different cabling and mounting problems. Older inner suburb homes bring solid walls and fragile ceilings. Cable routing usually goes through the roof space and down, and lath and plaster needs care wherever something is cut or fixed. High ceilings in those homes affect both mounting and acoustics. A three metre ceiling changes reflection patterns and makes in ceiling speakers considerably further from the listener.
Newer estates offer easier cabling and harder acoustics. Framed walls make routing simple while open plan layouts with hard floors and large glazing are the difficult listening environment. Rural and Hills properties often have the space for a dedicated room. Where a separate room is available, light control and isolation both become achievable in a way they rarely are in a suburban living area.
| Housing Type | Cabling | Acoustics |
|---|---|---|
| Pre war, double brick or stone | Through the ceiling and down | High ceilings, often carpeted |
| Post war brick veneer | Straightforward, framed walls | Generally reasonable |
| Newer estates | Easy if planned early | Hard floors, open plan, glazing |
| Two storey homes | Route between floors first | Depends on the room |
| Apartments | Limited, common property rules | Isolation matters to neighbours |
| Rural and Hills | Space for a dedicated room | Best case available |
| Item | Cost | Note |
|---|---|---|
| TV and soundbar setup | $300 - $900 | Where most households should start |
| Speakers set into the ceiling, per pair | $250 - $600 | Needs ceiling access |
| Full surround, existing room | $1,500 - $5,000 | Cable routing drives it |
| Cabling during construction | $600 - $2,000/room | Cheapest possible moment |
| Projector and screen room | $6,000 - $25,000 | Light control decides viability |
| Power and data outlets | $300 - $1,200 | Licensed electrical work |
Apartments, Strata and Keeping the Peace
A home theatre in an apartment or a strata property involves considerations a detached house does not, and owners frequently discover them after the equipment is installed rather than before.
Structural elements including common walls, the ceiling and the floor slab usually count as common property, which means fixing into them or running cable through them needs the corporation's agreement and not an owner's decision. A television mounted into a common wall is the everyday version of this. Sound transmission presents the larger practical issue, because bass travels through building structure far more readily than higher frequencies and a subwoofer in an apartment is audible in neighbouring units in a way the owner cannot hear from their own lounge. Several measures help genuinely. Isolating the subwoofer from the floor with a purpose made platform reduces structure borne transmission considerably. Keeping the subwoofer away from common walls matters more than its distance from the listener. Setting sensible limits on volume at night avoids the complaint that leads to a by law discussion. And where the building has by laws about noise, which most do, knowing them before installing is better than learning them from a letter. For an owner planning a substantial system, raising it with the corporation early is generally received better than presenting it afterwards. Soundproofing work sits at acoustic insulation.
What Home Theatre Installation Costs
A television mounted with a soundbar set up runs $300 to $900. That covers the mount, the fixing, cable management and configuring the equipment. Speakers set into the ceiling at $250 to $600 a pair fitted depend on ceiling access. An accessible roof cavity makes it straightforward while a two storey intermediate floor does not. A full surround installation in an existing room lands between $1,500 and $5,000. Cable routing through finished walls is the variable that moves it most.
Cabling during construction at $600 to $2,000 a room is the cheapest way to do any of this. Framing is open, nothing needs patching and future options stay available. A projector and screen room at $6,000 to $25,000 is a project and not an installation. Light control, mounting, cabling and the equipment itself all contribute.
Equipment joinery at $800 to $4,000 and electrical work at $300 to $1,200 round out most quotes. Ventilation in a cabinet is worth specifying rather than assuming it is covered. Building the cabinet is covered at shelf and cabinet installation. Installers around Adelaide differ noticeably in how they handle this point.
What to Look Out For
Deal with the room before spending on equipment. A rug, curtains and sensible speaker placement will do more than the next tier of hardware would. Do not mount the screen above a fireplace unless there is genuinely no alternative. Looking upward for a whole film is uncomfortable and it is the most common regret households report. Get cabling done while walls are open if any building work is happening. It is the one element that becomes several times more expensive once plasterboard is on.
Confirm who does the electrical work and that a certificate is issued. Adding outlets and circuits is licensed work in South Australia. Check whether setup and calibration are included and not installation alone, as licensing information for contractors is published at sa.gov.au. Guarantees on goods and services sit with the ACCC, contractor licensing with Consumer and Business Services and disputes have a pathway through SACAT.
How to Get Useful Quotes
Give the room dimensions and say where people sit. Those two facts shape the speaker layout and the screen size recommendation. Describe the wall construction and the floor. Double brick, brick veneer or stone changes the mounting and routing entirely, and a hard floor affects the acoustic advice. Say whether any building work is happening. Cabling during a renovation is a different proposition from retrofitting into a finished room.
State what you already own and what you intend to buy. An installer can work around existing equipment or advise on what suits the room. Mention light conditions if a projector is under consideration. Window size, orientation and existing window coverings decide whether it is viable. Have each quote state the cable route, the mounting method, whether making good is included, who does the electrical work and whether calibration is covered. Pin down those five and the quotes become comparable, and security work sits at smart home security.

Home Theatre Installation FAQs - SA 2026
What does home theatre installation cost in SA?
A TV mounted with a soundbar set up runs $300 to $900. In ceiling speakers are $250 to $600 a pair fitted, a full surround install in an existing room $1,500 to $5,000, and a projector and screen room $6,000 to $25,000. Cabling during construction is $600 to $2,000 a room.
Does the room really matter more than the equipment?
Yes, and it surprises people. A capable system in a bare room with tiled floors and large glazing will sound harsh, while a modest system in a carpeted room with curtains and soft seating sounds considerably better. A rug, curtains and sensible speaker placement outperform the next tier of hardware.
When should I run the cabling?
While walls are open, during a build or renovation. It is the cheapest work available and the only part that cannot be revisited. Run more than you think you need and use conduit with a draw string where possible, since a spare run behind a wall plate is worth having when something changes.
Can I mount the TV above the fireplace?
You can, and it is the most common regret households report. Looking upward for a whole film is uncomfortable, and a screen at eye level when seated transforms the experience. Where there is genuinely no alternative, a pull down articulating mount helps, though eye level remains better.
Will in ceiling speakers work for a home theatre?
They suit whole room listening rather than critical viewing, since they fire downward rather than at the listener. They are discreet and convenient, and that trade off is worth understanding. For a proper surround setup, speakers at ear height when seated do a different job.
Should I get a projector or a large TV?
Depends entirely on light control. A projector needs a room that can genuinely be darkened, and Adelaide's bright daylight with large glazed areas in modern housing is close to the worst case. Screen sizes and prices have moved, so a bright panel often makes more sense outside a dedicated room.
How do I stop the subwoofer annoying neighbours?
Bass travels through building structure far more readily than higher frequencies, which is why it carries into neighbouring units. Isolating the subwoofer from the floor with a purpose made platform helps considerably, and keeping it away from common walls matters more than its distance from the listener.
What about my wall construction?
It decides everything about mounting and routing. Double brick is solid through, so cable usually goes through the ceiling and down, and in wall speakers are not an option. Brick veneer has framing behind the plasterboard, which makes routing straightforward, though a heavy screen still needs to reach the studs.
Do I need an electrician?
For any new outlets or circuits, yes, since that is licensed work in South Australia. A dedicated outlet behind the screen is worth doing rather than running a lead down the wall, and a wired network run to the equipment position removes a class of streaming problem entirely.
Where should I spend first?
Screen position and seating, which are free. Then room treatment through furnishing, which costs no more than furniture you would buy anyway. Then speaker placement. A capable soundbar with a subwoofer is where most households should stop, since that step is enormous and the next one is a refinement.
