A beginner's guide to setting up surround sound speakers

Why placement matters more than price

You can spend a small fortune on speakers and still end up with a soundstage that feels flat, muddled and oddly distant. The single biggest improvement most people can make has nothing to do with upgrading kit — it is simply putting the speakers they already own in the right places. Sound is directional, and your ears rely on tiny differences in timing and loudness to work out where things are happening on screen. Get the geometry right and even a modest five-speaker package will convince you a helicopter is hovering above the sofa.

The golden rule is simple: position speakers at ear level and angle them towards the main listening area. Everything else in this guide is a refinement of that one idea.

Start with a simple five-point-one layout

Five-point-one is the standard beginner's setup, and it is worth getting this right before you dream of adding more channels. The numbers refer to channels, not to the number of boxes you must buy — the ".1" is a dedicated low-frequency effects channel, not a sixth speaker.

  • Front left and front right — either side of the screen, doing the bulk of the music and effects work.
  • Centre — arguably the most important speaker of the lot, as nearly all dialogue comes from here.
  • Surround left and surround right — beside or just behind you, for atmosphere and effects that fly past.
  • Subwoofer — the deep rumble and thump. One is plenty to begin with.

If your budget or your room only stretches to a soundbar and two rear speakers, that is fine. The layout logic below still applies, and you can add channels later once the basics are solid.

Getting the front three right

Seated ear height in a typical living room is around 1.1 to 1.2 metres. Measure from the floor to your ear while you sit in your usual spot, then set the tweeters — the small drivers near the top of each cabinet — at that height. If a speaker has to sit on a low unit, tilt it back slightly so it fires upwards towards your head.

Place the front left and right speakers so they sit roughly 22 to 30 degrees either side of the centre of the screen, measured from your seat. In practice, a speaker about 2.5 metres away from you ends up around 1 to 1.3 metres to the side of the television. An equilateral triangle between your head and the two speakers is a good starting point. Turn each one inwards very slightly, perhaps 10 to 15 degrees, so it aims just past your ears rather than straight down the room.

The centre speaker is where most people go wrong. It should sit directly above or below the screen, as close to ear height as you can manage, and angled up or down towards you. Never hide it inside a closed cabinet, and never tuck it behind the television. Dialogue clarity lives or dies here.

Surrounds and the space behind you

Surround speakers belong to the sides and slightly behind the listening position, at roughly 90 to 110 degrees from the front. Draw an imaginary line straight out from each ear and place the surrounds just behind it. They should be at or slightly above ear level — up to about 60 centimetres higher is fine if wall-mounting is easier — and angled in towards the sofa so the sound arrives at your ears rather than sailing past them.

Avoid putting them directly behind your head, and avoid firing them into a wall a foot away. A little breathing room makes a surprising difference to how open the rear effects sound. If your sofa is pushed hard against the back wall, try to bring it forward by even 30 centimetres; it gives the surrounds somewhere to work with.

Bass, crossovers and the subwoofer

The subwoofer is the one speaker that does not need to be at ear level, because low frequencies are far less directional. Start with it in a front corner, a quarter of the way along the wall from the corner, or beside the sofa. Corner placement gives the most output but can sound boomy; moving it out into the room usually tightens things up.

A useful trick is the "subwoofer crawl". Put the sub in your listening seat, play something bass-heavy, then crawl around the floor near the walls. Wherever the bass sounds tightest and most even is roughly where the sub belongs. Once it is in place, set the crossover in your amplifier to around 80Hz so the sub handles the deep stuff and the main speakers do the rest.

Fine-tuning once everything is in place

With the speakers positioned, run the automatic calibration routine built into your amplifier. It will measure distances, levels and room acoustics, and it gets you most of the way there. Then check a few things yourself.

  • Distances — confirm each speaker's distance in metres matches reality. Errors here smear the timing of effects.
  • Levels — sit in your usual spot and adjust each channel until dialogue and effects feel balanced rather than front-heavy.
  • Familiar material — play a film you know well. The surround channels should support the action, not distract from it.
  • The room itself — rugs, curtains and a filled bookshelf all tame harsh reflections. Bare floors and glass make everything sound brittle.

No two rooms behave alike, so expect to nudge things over a few evenings rather than in one sitting. Small moves of 15 to 20 centimetres often make an audible difference. Take your time, trust your ears, and enjoy the moment the whole thing clicks into place.

Choosing between soundbars and separate speaker systems

Blackout curtains block outside light and reduce reflections on your television screen. They also help contain sound within the room for a more immersive film night.
