Why slots in corners
Posted: Thu Apr 03, 2003 2:56 am
John, you seem to prefer slot absorbers in corners as opposed to hangers. Is this true, and if so, why? I was under the impression that the corners were the best place to deal with low bass since the nodes pile up there, but slots seem to deal more with upper bass/lower midrange.
Also, in the yahoo acoustics group there are several people who recommend putting rigid fiberglass like 703 across corners with insulation behind for bass trapping. What do you think about that method?
I'm skeptical about it myself. A couple of weeks ago I did a test where I took two of my freestanding 8'x4' 703 panels and put them across the back corners (without insulation behind). I also moved out the bottoms of the other 703 panels in the room about 6-8 inches with the tops still leaning against the wall. The total effect seemed minor and wasn't very helpful. The worst bass notches got even worse and lowered in frequency by about 3-5 Hz.
Thanks,
J.J.
