yep, I learned that after running LD's for awhile, namely the Neumann's since the TL's have more natural rolloff and haven't been as bass heavy. With omnis or cards, I almost always run a mild rolloff with the V3 (& V2 when I had one). I think I used a -6db/octave slope @ 75Hz. I don't use rolloff when running hypers from the section or anything on stage.
