A soundbar suits rooms up to about 25 m² (270 sq ft), a soundbar with subwoofer and rears or a starter 5.1 suits an average living room of 25 to 35 m², and a receiver with 5.1.2 speakers suits 35 m² and larger. Installed, a soundbar is $350 to $1,100, a 5.1 system $1,270 to $2,970 and a 5.1.2 system $2,230 to $5,530, using Pixl’s posted install prices and market estimates for equipment.

- Sound system by room size
- Front speaker gap calculated by seat distance
- Pixl install lines for each choice
- Pay after the job
- Start from the room: under 25 m² a soundbar is enough, over 35 m² separate speakers pay off.
- An average living room can go either way. A 5.1 system costs about $470 to $1,470 more installed than a soundbar with rears.
- Pixl installs a soundbar for $50 plus $50 to mount, and 5 speakers for $150 plus $20 for a subwoofer.
- Front speakers sit roughly 22 to 30 degrees either side of centre. At a 3 m seat distance that is a gap of 2.4 to 3.5 m.
You know your room size and want to know whether a soundbar or a receiver with speakers fits it, and what it adds up to.
You want a general soundbar vs surround explainer. Read soundbar vs surround sound.
Which sound system fits which room size?
Room size is the first filter. A soundbar fills a small room easily, while a large room asks for separate speakers and a receiver that can move more air. The table below is a planning guide, not a standard, because ceiling height, furniture and how loud you listen all change the answer. Equipment ranges are market estimates, not a fixed Pixl price, and the install column uses Pixl’s posted prices.
| Room | Floor area | Sound system that fits | Equipment, market estimate | Equipment plus Pixl install |
|---|---|---|---|---|
| Bedroom or den | up to 14 m² (150 sq ft) | Soundbar, 2.1 or 3.1 | $250 to $600 + $100 | $350 to $700 |
| Condo living room | 14 to 25 m² (150 to 270 sq ft) | Atmos soundbar with wireless subwoofer | $450 to $1,000 + $100 | $550 to $1,100 |
| Average living room | 25 to 35 m² (270 to 380 sq ft) | Soundbar with sub and rear speakers, or a starter 5.1 with a receiver | $700 to $1,400 (soundbar) or $1,100 to $2,800 (5.1) | $800 to $1,500 (soundbar) or $1,270 to $2,970 (5.1) |
| Large family room | 35 to 50 m² (380 to 540 sq ft) | 5.1 or 5.1.2 with a receiver | $2,000 to $5,300 (5.1.2) | $2,230 to $5,530 (5.1.2) |
| Open basement or great room | over 50 m² (540 sq ft) | 5.1.2 or 7.1.2 with a receiver and a strong subwoofer | $2,800 to $7,500 (7.1.2) | $3,090 to $7,790 (7.1.2) |
Where two columns fit, as in an average living room, the choice comes down to wiring. A soundbar with rears avoids speaker cable across the room. A 5.1 system costs about $470 to $1,470 more installed, and gives you real speakers and an upgrade path.
How do the two approaches compare?
| Factor | Soundbar | Receiver with separate speakers |
|---|---|---|
| Wiring | One HDMI cable and a power cord | Speaker cable to every speaker, plus HDMI to the receiver |
| Placement | Under or above the TV | Speakers around the seat, and a receiver with ventilation space |
| Surround effects | Simulated from the bar, plus rears if supported | Real speakers in real positions |
| Upgrade path | Limited to the brand’s add-ons | Swap the receiver, speakers or subwoofer one at a time |
| Setup effort | Minutes with ARC or eARC | Placement, wiring, then calibration |
| Pixl install line | $50 to install and connect, $50 to mount | $90 for 3, $150 for 5, $210 for 7 or $270 for 9 speakers, plus $20 for a subwoofer |

How far apart should the front speakers sit?
In a receiver system, the front left and right speakers sit on either side of the screen at an angle from your seat. Dolby’s published layouts put them roughly 22 to 30 degrees either side of centre. The gap is twice the seat distance times the tangent of that angle.
| Seat to front speakers | Gap at 22 degrees each side | Gap at 30 degrees each side |
|---|---|---|
| 2.5 m (8 ft) | 2.0 m | 2.9 m |
| 3.0 m (10 ft) | 2.4 m | 3.5 m |
| 3.5 m (11 ft) | 2.8 m | 4.0 m |
| 4.0 m (13 ft) | 3.2 m | 4.6 m |
| 4.5 m (15 ft) | 3.6 m | 5.2 m |
If your gap comes out wider than the TV wall allows, use the narrower angle. A soundbar avoids this planning step because the whole front stage is in one bar.
What if the room has a low ceiling or open stairs?
| Condition | What it changes | Plan for |
|---|---|---|
| Low basement ceiling | Limits upward-firing height speakers | A 5.1 layout, or check the manufacturer’s ceiling guidance |
| Open stairs or open plan | Bass and sound spread beyond the seating area | A subwoofer with level controls, and more output from the receiver |
| Condo with shared walls | Bass travels through the structure | A soundbar with night mode, or a smaller subwoofer. See basement and condo home theatre planning |
| Seat against the back wall | Rear speakers have no room behind you | Side placement or a soundbar with side-firing drivers |
| Furniture blocks the sides | Surround speakers cannot reach their positions | Wireless rears, or stands instead of wall mounts |
What does the install add for each choice?
| System | Pixl lines | Total |
|---|---|---|
| Soundbar | $50 install + $50 wall mount | $100 |
| 5.1 (5 speakers + subwoofer) | $150 + $20 | $170 |
| 5.1.2 Atmos (7 speakers + subwoofer) | $210 + $20 | $230 |
| 7.1.2 Atmos (9 speakers + subwoofer) | $270 + $20 | $290 |
The speaker prices are for installing and connecting equipment you supply. New speaker cable inside finished walls or ceilings is not in the posted price, so send a photo of the room if you want it hidden. The TV is priced separately: see TV mounting service.
Which should you choose?
| What matters most | Choose |
|---|---|
| Low cost and easy setup | A soundbar with a wireless subwoofer |
| No speaker cable across the room | A soundbar with rear speakers, if the brand sells them |
| Real directions in a large room | A receiver with separate speakers, 5.1 or 5.1.2 |
| Upgrading one part at a time | A receiver with separate speakers |
| A condo with close neighbours | A soundbar, with night mode |
Soundbar vs receiver: frequently asked questions
Is a soundbar enough for a large room?
Often not. In a large room separate speakers and a receiver give more output and put surround effects where you can hear them. A soundbar with a wireless subwoofer and rear speakers can stretch to an average living room.
What size room is a soundbar good for?
Soundbars suit bedrooms, condos and average living rooms, up to roughly 35 square metres (380 square feet) as a planning guide. Past that, separate speakers pay off.
Do I need a receiver for a 5.1 system?
Yes, for passive speakers. The receiver powers the speakers and switches your sources. Some wireless speaker systems build this in, so check the specification.
How much does it cost to install a 5.1 system with Pixl?
Installing and connecting 5 speakers is $150 and a subwoofer is $20, before tax. The TV, receiver and speakers are extra, and you pay after the job.
Can I start with a soundbar and move to a receiver later?
Yes. Plan the TV wire route and the receiver spot first. A soundbar is $50 to install and $50 to mount, and it can move to a bedroom later.
Where should the receiver go?
Somewhere with space around it for ventilation, close to the TV and the router if you use wired network. Do not box it into a closed cabinet.
Do you run speaker wire in the walls?
In-wall speaker cable is not part of the posted prices. Send a photo of the room and we tell you what Pixl does and what to arrange separately.

Sources and method. Speaker gap = 2 x seat distance x tan(angle), calculated for 22 and 30 degrees; for 3.0 m this gives 2 x 3.0 x tan(22) = 2.4 m and 2 x 3.0 x tan(30) = 3.5 m. The 22 to 30 degree range follows Dolby’s published speaker layouts. Room size bands are a planning guide, not a standard. Installed cost = equipment market estimate (not a fixed Pixl price, rounded) plus Pixl posted prices, checked October 27, 2026. Square feet are square metres x 10.76, rounded.
