I’m planning to upgrade my home theater setup and need ideas for speaker placement, TV or projector choices, seating, lighting, and cable management. Please share photos and details of your setup so I can see what works in real rooms.
Room dimensions and whether the space is rented matter more than the equipment list. A setup that works in a closed 12-by-16-foot room can be awkward in an open living room, especially when doors, windows, and walkways force the seating off-center.
For a typical multipurpose room, I’d keep it simple: a 75- to 85-inch TV, a 5.1 speaker layout, and one main seating row. Put the center speaker as close to ear level as the furniture allows, angle the left and right speakers toward the main seat, and place the surrounds slightly behind that seat rather than high in the front corners. Don’t push the couch against the rear wall if you can avoid it. Even 18 to 24 inches of space can improve surround effects and reduce boomy bass. A projector makes more sense when you can control daylight and fit a genuinely large screen. Otherwise, a TV is usually less fussy.
Plan the outlets and cable routes before buying furniture. Paintable surface raceways are a decent option when you can’t run wire inside the walls, and they look much better than loose cables along the baseboards. For lighting, dimmable lamps or bias lighting behind the TV are easier to live with than ceiling lights shining toward the screen. I’d sketch the room from above, including doors and walking paths, before choosing anything. That catches more problems than copying someone else’s gear list.
A perfectly symmetrical setup can sound worse than a slightly awkward-looking one if the subwoofer and seating land in bad spots. Before permanently mounting anything, put the sub where the main seat will be, play a bass-heavy track, then walk around the room and mark where the bass sounds most even. That spot is usually a better starting point for the sub than whichever corner looks cleanest.
I agree with @snailcrash about keeping the couch off the rear wall, but I wouldn’t choose TV size from room dimensions alone. Viewing distance and what you watch matter more. An 85-inch screen can feel normal for movies from 9 feet away but overwhelming for low-quality cable channels. Projectors bring fan noise, light control, bulb or laser considerations, and more complicated HDMI runs, so the giant image comes with real maintenance.
For cable management, run conduit rather than burying a single HDMI cable if the walls are open. HDMI standards and equipment change, while conduit lets you pull a replacement later. Label both ends of every speaker wire, leave a service loop behind the receiver, and keep power cords separated from signal cables where practical. A thick rug, curtains, and a few fabric-covered acoustic panels will often improve the room more than spending the same money on upgraded speakers.
Tape the proposed screen outline on the wall and live with it for a few evenings before buying anything. Sit in every seat, check whether anyone has to look upward, and make sure doors, cabinets, and walkways still work. That quick mock-up catches more problems than a room-size calculator.
I’d plan the front wall around the center speaker first. A huge TV squeezed above a cabinet can leave the center channel near the floor or stuffed inside furniture, which hurts dialogue clarity. Keep its front edge clear of the cabinet, aim it toward ear level, and leave ventilation space for the receiver. Surround speakers can look slightly uneven and still work well after calibration. Putting them too close to someone’s head is much harder to fix.
The conduit suggestion is ideal during construction, but surface-mounted raceway is a perfectly decent option in a finished room and is easier to change later. For lighting, use dimmable lamps or indirect LED strips behind the seating rather than ceiling lights that reflect off the screen. I’d spend money on blackout curtains, a quiet equipment fan, and comfortable seating before decorative theater signs or extra speakers. Those boring details affect every movie.
The receiver does not have to sit under the TV. That arrangement is common because it photographs neatly, not because it is especially convenient. A ventilated cabinet on a side wall can keep display lights, fan noise, and cable clutter away from the screen. Just leave access for discs, consoles, and the occasional hard reset. Equipment always chooses the least convenient moment to need attention.
I would build around a large TV, one couch, and 5.1 before considering extra ceiling speakers. Atmos is nice when the room supports correct placement. Random speakers mounted wherever joists allow are mostly expensive decoration. Keep the center channel directly below the screen, with the left and right speakers pulled forward from the wall enough that cabinet doors and TV furniture do not block them.
@capt_badger mentioned ventilation, and that deserves more attention than theater photos usually show. Closed cabinets trap heat. Open-backed furniture, quiet fans, and several inches above the receiver are worth planning from the start. Do not bundle power bricks into a warm knot behind it either.
For lighting, put separate dimmers on the screen area and the seating area. You want enough light to find a drink without washing out the picture. Small low-level lamps or step lights work better than turning the entire ceiling back on.
Cable management should remain accessible, not merely invisible. Use raceway or conduit, label everything, and keep spare pull cord in any conduit. Leave enough slack to slide equipment out without disconnecting half the room. A perfectly clean installation that requires removing the TV to replace one cable is not perfectly clean. It is a future repair job.
Don’t buy the seating last; it can undo an otherwise sensible layout. Tall recliner backs can block surround speakers, wide armrests push listeners off-center, and fully reclined chairs may need far more wall clearance than the listed dimensions suggest.
Mark the complete reclined footprint on the floor before mounting speakers. Check sightlines from the reclined position too, since your eye level and viewing angle change noticeably.
I’d favor lower-backed seating with a movable ottoman in a smaller room. It is less “theater-looking,” but usually gives cleaner surround sound and makes the room easier to rearrange.
If you share walls or floors with neighbors, the subwoofer decision matters more than whether the TV is 77 or 85 inches. Your neighbor will not admire your beautifully even 25 Hz response at midnight.
In that situation, I’d use a modest sub close to the main seat, enable the receiver’s night mode, and avoid placing it against a shared wall. Isolation pads can reduce cabinet vibration, but they do not magically stop deep bass traveling through the building.
This is where I’d slightly push back on the subwoofer crawl advice: the best measurement spot may be the worst practical spot. Choose the best location you can actually use without blocking a walkway or starting a small war downstairs, then let room correction handle what it reasonably can.
A big glossy TV in a room with any light behind the seating turns into a mirror the second a dark scene comes on, and no amount of picture calibration fixes reflections. That gets missed a lot when people fixate on screen size.
I’m with @hyperscript_86 on picking seating early, but I’d stretch that further: figure out where windows and lamps land relative to the screen before you commit to a TV at all. @neontiger7942 makes the point everyone skips, room correction only cleans up so much, and the same goes for glare. If you can’t kill the light behind the couch, a matte-ish screen or careful TV angle matters more than jumping from 77 to 85 inches. For me the quiet upgrade is controlling what’s behind you, not just what’s on the wall.
Nobody gets this right in one pass, so budget for a second round of small changes after you’ve actually watched a few movies in the room. You’ll move the sub, re-aim a surround, and probably wish the couch was a foot different. That’s normal. Treat the first install as a draft, which is exactly why the raceway advice beats sealed-in conduit for most people finishing an existing room.
The thing I keep seeing skipped here is that the same room usually pulls double duty. It’s movie night on Saturday and background news on Tuesday morning. @neonsprite is right about glare, but the flip side is you can’t blackout-curtain a room your family uses at 9am and expect anyone to be happy. If it’s a shared living space, plan for the everyday case first and the dark-cave case second, not the other way around. A screen that only looks good with the lights off is a screen you’ll fight with constantly.
One correction on the gear order everyone’s implying: don’t sink money into speakers and calibration until you know the seating is final. @hyperscript_86 nailed why. I’d go further and say pick the couch, then the screen, then audio, in that order. Reversing it is how people end up with a center channel aimed at nobody. And honestly, for a first upgrade, a solid 5.1 that’s placed correctly will beat a sloppy Atmos setup every time, so skip the ceiling speakers until the basics are locked in.
