I use OmniMic most of the time, but I've used REW. :) My point was just to not use traps willy-nilly. In my rooms they've always made an improvement though.
How Are You Using Bass Traps?
When it comes to room treatment I found bass traps were easy to deploy. I got dense studio foam bass traps that were 1' x 1' x 2' and placed them right in the front corners roughly from floor to ceiling. Immediate improvement in the tightness and clarity of the bass in my room. What advice would anyone have who wants to use bass traps in their room?
