I just can't figure this out. I have four 12 inch subs that I'm using. The basement is 25 ft long by 20 ft wide. I can't seem to get even coverage in the marked (rectangular) area. I always seem to get a dead spot (no bass at all) just to the right of the stairs (shown by the circle).
One setup I had, shown in the second picture, the subs (green) on the right were out of phase with the subs on the left. That gave me tons of deep bass on the wall with the doors, but towards the middle of the basement, the bass would cancel. Then I had my full-range speakers (one in each corner) fill in the bass, and that sounded decent. This setup somehow took care of the dead spot in front of the stairs, but I didn't like the idea of having half the subs out of phase, and the cancellation towards the middle.
Does anyone have any ideas to get pretty even coverage? I have tried just about everything, from a sub in each corner, to all the subs in one corner, to the subs spread out along one wall and all firing one way. I got the best results with half the subs out of phase and the mids filling in. Give me something else to try, because I'm out of ideas.
