I working on the design for our new theater in our new house, the space available is 13' x 23' x 9'. There will be two rows of seating with three seats per row. The first row of seats has the viewers approximately 14.5' away from the 100" 16x9 screen and is on a 9" riser. The second row of seats has the viewers approximately 21.5' away from the screen and the back row is placed against the back wall, and is on a 18" riser. My question is where is the best location for surround speakers and the best type of speaker, ie, direct firing monopole or dipole speakers, and the best configuration, ie 5.1, 6.1, or 7.1? Thanks in advance for any advice.
