When is a room too small for HT? I'm considering using my spare bedroom, but it's only 13'10"L (including the depth of the closet (about 2') at the headend of the room), 10'7"W, 8'0"H. How many rows of seats could I get in there? Unfortunately, this is the only room I can use The two issues I have with this room is that the entryway protrodes into the room about 3' in the corner of the headend, slightly wider than the doorway and it's adjacent to the master bedroom, so soundproofing is a big concern. This build will be everything, including equipment. On a positive note, the spare bedroom is where I installed the multimedia distribution center when I did the living room, so it already has a dedicated circuit wired with 12/2 Romex (currently under a 15A circuit breaker at the box). I'm considering Denon, Klipsch Classic, an SVS powered cylindrical sub and possibly a projector although I don't know if I should be looking at a DLP or CRT projector I've done what I can with the living room -- RPTV, Dolby 5.1, room darkening shades, 50% grey walls (well, as close to 50% as the GF would allow ), Berkline 099 seating, etc. Even with all this, I still want a dedicated viewing area.
