I've got a 16x19 home theater room with two "rows" of seating, the second (back) being on a six inch riser. I set the side surrounds (Monitor Audio) just behind the second row on the side wall of the room. My question is: Will adding rear surrounds add much if I place them on the back wall? This would make them only 4 feet away physically from the side surrounds. The second row of seating is about two feet away from the back wall so they would also be very close to where you would be seated in the second row. When I wired the room I read somewhere that putting the side surrounds in front of the listening postion resulted in a disorientation of the soundfield where the sound doesn't make sense. As a result I placed the side surrounds well back in the room so that they were behind both listening positons. Should I consider moving them if I add back surrounds? I am 60/40 music over HT im my listening habits. I've got a 7 channel receiver so its no trouble to make the change there. Also, with two rows does anybody have any suggestions as to how best to set up the speaker delays for the best "overall" sound?
