| Re: DIY Bass Trap....Will it Work ?
Yeah, my riser had terrible effects on the acoustics when I first built it. Nasty "suckout" of a wide region of bass with a pronounced "ring" at certain frequencies.
I added a layer of 1/2" ply over the existing 3/4" and stuffed it with insulation (batting with paper back). Immense change. Much tighter bass, no more boom at some notes, nonexistant at others. I didn't know it at the time, but I was basically "tuning" a big panel absorber.
