Home Theater & Media Rooms

Almost every disappointing theater we are called into has good equipment in it. What it does not have is a design: the screen is the size that fit the wall, the seats are where the room suggested, and the speakers went where the joists allowed. The equipment is then blamed for a result that was decided before any of it was bought.

We start with seating and screen. Viewing distance sets screen size, screen size sets projector or display choice, and seat position sets where the speakers and subwoofers have to be. Those relationships are fixed by geometry, and working them out on paper costs nothing compared with discovering them after the drywall.

Acoustics matter more in a small room than in a large one, which is the opposite of what most people assume. A basement theater with hard parallel walls will do things to dialogue that no amount of processing corrects. Treatment at the first reflection points and control of the low end are usually the highest-value money in the whole project, and they are invisible in the finished room.

In a dedicated room the front three channels belong behind an acoustically transparent screen, which is the only arrangement where the dialogue actually comes from the actor's mouth. In a media room that is rarely on the table, and the honest choice is between in-wall channels flanking the display or a properly built bar under it.

In-wall front channels are the better answer when the wall can take them. A serious in-wall has a rigid sealed baffle and enough cone area to keep up with a subwoofer, which is what separates a front channel from a background music speaker. They finish flush, take paint, and disappear into the wall the room already has.

Where an in-wall front stage is not practical, a soundbar cut to the exact width of the screen in a true three-channel configuration is a real alternative — not the processed stereo bar that ships with a television. The centre channel is a discrete channel, and dialogue stops wandering.

Immersive formats specify where speakers go, in angles from the listening position, and those angles do not care where the joists run. Getting height channels wrong is the single most common fault we find in existing rooms — usually because they went in wherever the ceiling was easiest to open.

We lay the positions out against the seating first and then work out how to build them, which sometimes means furring a ceiling or moving a can light. That is a conversation worth having during construction and an expensive one afterwards.

Surrounds and heights should also match the front stage in character. Mixing an aggressive front with a soft ceiling speaker produces a sound field that moves oddly as an effect pans overhead, and no amount of calibration fixes a mismatch in the drivers themselves.

One subwoofer in one corner gives one seat good bass and everybody else something else. Room modes mean level at 40 Hz can vary by more than 15 dB between seats in the same row, and the seat that sounds best is rarely the one anybody sits in.

Two subwoofers in the right positions flatten that out far more effectively than one bigger subwoofer does. Where the room and the budget allow it, that is the recommendation, and it is placement rather than power doing the work.

Calibration finishes it. Levels, distances and crossover points get measured and set rather than left at the defaults, and the target is a consistent result across the seats people actually use — not the best possible number at the microphone position.

A theater with four remotes on the table is a theater that gets used for television. The measure of the install is whether somebody who was not there when it was commissioned can sit down and start a film.

That means one action — lights down, screen down, projector on, source selected, audio mode set — behind a single button on a panel, a keypad or a phone. The complexity stays in the programming where it belongs.

It also means the equipment does not live in the room. A ventilated rack in a closet or a basement, with signal distributed to the room, keeps fan noise and standby lights out of a space whose whole purpose is dark and quiet, and makes servicing something that happens without dismantling the seating.
