Speaker Placement and boundary problems

The 12, 10, and two 8's worked perfectly. My best sub configuration was an M&K MX-350 w/ and MX-150 stacked on top of it. Anyway, I haven't tried an odd number of subs stacked in the same corner; but, give stacking in the same corner a shot.

BTW, thanks to prerich for starting the thread.

Stacking two subs in one corner will only provide satisfactory results from one point in the room. A sub in each left/right corner will provide satisfactory results over the entire width of the room, but will have some problems with room length, especially along the back wall.

I would love to measure the distortion and frequency response of your stacked subs. I would have loved to measure your 12, 10, and two stacked 8's as well. I bet it sounded good to your ears, but it would measure very poorly over most of the room, with some areas getting a ton of bass, and others having it sucked out. You would be surprised how forgiving our ears are in the deep bass, and how measurements are not so forgiving.
