Well i pushed the woofer in and out and it moved freely with no noises.
yes all my setting are correct, i use audyssey, it calibrates my system for me. and before anyone says anything about audyssey, i've been using it for 8 months now and its been fine. i dont have an spl meter but audyssey does that for you anyway. again, before anyone comments about that, like i said its been sounding fine for 8 months, its not that.
its definitely my sub.....i put on a movie today and it was boomy like crazy, it sounded nasty. when i wached casino rayale i always had a little boom yea, my room is square and i dont have any treatments, but this was bad! it never sounded like this before. infact audyssey fixed the boom i was having with that movie and others.
the scene near the end when the building is crumbling down, that was the the worst. it didn't sound like a crumbling building, that whole scene was boomy and distorted. never sounded like that before.
