Small room home theater: how to make it work

The screen: bigger than you’d think

The viewing-angle rule works in your favor in a small room. You sit close, so a modest screen fills a lot of your view:

Eyes to screen	Screen for 30–40°
6 ft	44–60 in
7 ft	52–70 in
8 ft	59–80 in

A 65-inch TV in a 12 × 11 ft den, viewed from about 8 feet, fills about 32° of your view: inside the recommended band, and plenty for films. What limits screen size in small rooms is usually the wall: allow for the TV’s full width (about 57 inches for a 65-inch set) plus some space either side.

Seating: off the wall if you can

In small rooms the sofa often ends up against the back wall. That’s fine for the picture, harder for sound:

• Bass builds up at walls. A head right against the back wall sits in a bass peak. CEDIA/CTA RP22’s entry-level guideline is at least 0.5 m (about 20 inches) from your head to any wall; even a foot of space helps.
• Avoid the exact middle. The room’s first length mode cancels at the halfway point, so a sofa in the dead center of a small room can lose bass.
• One row. A second row in a small room usually ends up against the back wall and too close to the rear surrounds.

Sound: soundbar or 5.1 with side surrounds

• A soundbar is the simplest fit: one speaker under the TV, nothing on the floor. See soundbar placement.
• 5.1 with side surrounds beside the seats, at about ear height, if you want surround. Skip rear surrounds if they’d be right behind your heads.
• Height speakers (5.1.2) fit small rooms well: two in-ceiling speakers slightly in front of the seats, or up-firing speakers if the ceiling is flat and between about 7.5 and 14 ft high.

Small rooms also get a bass boost below their first resonance, which SVS calls room gain, so a modest subwoofer can sound big. Place it with the subwoofer crawl.

Reflections are closer

Walls are close to the speakers and the seats, so first reflections are loud. A rug, curtains, a full bookshelf and two to four panels at the side-wall reflection points make a small room sound larger and clearer. Use panels at least 2 inches thick; GIK recommends 4 inches for film and music.
