need help designing an audio/HT room

<< < (2/3) > >>

bpape:
If you can make a room with the front and rear wall parallel and the 2 side walls splayed to be wider toward the back, that's a good solution.  The taper should be 1" per foot on each side.  Less than that and you still have standing wave issues.

Not sure how I'd be able to post a copy, so I'll attempt a crude diagram.

The "O's" mark the side wall areas where I'm considering in walls. Not sure aesthetically if it would look good to install in wall speakers in an asymmetrical room, so that's why I'm also considering mounting  those 2 in the ceiling. My real focus for the room is 2 channel stereo and any HT application is secondary only. Having the side walls wider at the rear isn't possible.The site links are great, so I am learning quite abit.

Thanks

So it's not possible to simply orient the room the opposite way?  That, combined with a small slant to the front and rear wall would provide what I described and you'd still pretty much maximize the space available.

Angling the sidewalls toward the front will make your acoustic problems worse by pushing reflections forward toward the front wall where your stereo soundstage is. You want to control reflections there very carefully to have a big clear sound. Swapping ends would be ideal.

Nick B:
I never thought about swapping ends, but it's possible if I move a door. As to angling both side walls, that isn't possible for aesthetic and design reasons. I would still like opinions on placing the 2 rear speakers in the ceiling. Would I get decent HT sound doing that? Thanks
