Kind of have a perplexing issue. I have a dedicated media room approx. 16'X18', with 8 seats (row of 4 in the front and 4 in the back on a 6' riser). I've tried placing my SVS PB-10 NSD sub in the back right corner, and also in the front left corner of the room. Problem is, after running the Audyssey calibration on my Denon receiver, the bass seems boomy and overpowering in the back row, especially the left rear seat, and a little weak in the front row (except for the left seat which is closest to the sub). If I lower the output level it would just weaken it more in the front row. I've been trying for awhile to get a good balance throughout the room. I've tried different phase settings and also moving the sub away from the corner a bit, but didn't resolve anything. I may try swapping out the SVS sub with the Paradigm Ultracube 10 which I'm using in the living room to see if it fares any better. Does anybody have any tricks or suggestions on how to get a little more consistency for the bass output in the room?
