I have a 19'x13' room for my theater. I sit along the 19' wall because I get better imaging and better bass response from the front channels along the longer wall (as reccommended by Dunlavy Audio room considerations http://www.dunlavyaudio.com/audio_files/listening.html ). If I put the front channels along the shorter wall, imaging collapses and the bass is too boomy. So I have fixed the front soundstage but I am forced to sit along the back wall. If I put my dipole surround speakers on the side walls they would also be very close to the back wall in the corner, and I'm not sure if this is ok. The local IMAX theater puts the surround channels up high in the corners of the back wall facing down toward the listener. I'm thinking monopoles my be better in my situation. I would like to know if anyone else has a similar room setup or opinions from professionals. Thanks.
