I strongly recommend your buying F. Alton Everest, "Sound Studio Construction on a Budget", which covers all types of audio rooms including home listening rooms, or his "Master Handbook of Acoustics, 4th Edition". You'll get all the answers to your questions, and a whole lot more. This book should be a Bible for audiophiles who care, as all should, about the room they put their components in. Among other things, you'll learn why smaller rooms pose more problems than larger ones, for resonant modes, and also how to choose dimensions to minimize those problems. Good luck!
ROOM SIZE QUESTION
I am looking to buy another home and wish to have a "media room" for stereo and big-screen TV. One home currently on the market has a room that is 16x14 with a 10'ceiling. Seems like something longer would be better (maybe 20x14??) but looking for other's experience with a similar room size. Also, a few comments as far as seating placement, speaker placement and TV placement (relative to this room and to each other) would be helpful.
Thanks
Jim
