I have a line array with 6 PE IB15's and everything is great. But.... my rear wall does flex noticeably with heavy output. (wall opposite the array. Walls 20 feet apart) the wall section is 9.5 ft W x 12 ft H.
It flexes enough that it would shake my projector off the shelf! (projector shelf on same wall)
So I had to build a stand to mount the projector on. A 6x6 pressure treated post, bolted to the concrete (slab) floor to isolate it from the walls.
Anyway, from my reading here, I assume that this does cause a difference due to the "Bass trap" effect of the wall flexure.
If this is true, would stiffening the rear wall provide a worthwhile benefit?
