Damn, one of my paradigm studio 40's was crackling, I noticed it while playing NHL 2K3 on my x-box... damn annoying. So I took the speaker down and brought it upstairs to my 2 channel setup. No issue with music odd! So I thought, maybe a loose connection or something and jaring it fixed it. So I returned it to my theatre with the same results, crackling. So thought, maybe it was my amp. I moved the speaker to my centre channel location (different amp different wires) nope same problem. But it was only there on the test tone! So I turned up the test tone and it was worse. I tried my amp on other speakers with no crackle. So the amp and wires are eliminated must be the speaker. Brought it to my dealer, they said they tried everything and cannot reproduce the problem! I think I'll call back and make sure they tried it at like 80db on the test tone. Because you can't tell any other way. I really hope I don't have to drive all the way accross town to get this thing and it's STILL bad.
