I have this huge area (big family room opening up into kitchen and beyond that living room and dining room with vaulted ceiling) and I am using a Paradigm PS-1000 v4 sub. For the fun of it on the weekend I also hooked up a second sub (Mirage BPS-150) to see how much more muscle there would be. I stacked the two in a corner and then found I had to cut the SW volume on my receiver to avoid having too much bass. We were watching a movie last night and my wife asked me to turn the sub(s) off because she could not hear the dialogue clearly. To me there seemed to be too much bass no matter how I adjusted the system. I am now back to using just the Paradigm sub and it seems to sound more balanced. The room (14 by 24) might be a problem, but at least it's not square. Anyone else find two subs overkill? Many would say the room is too large for just one sub, but I am not trying to blow the roof off when I watch a movie.
