I just recently got a SVS 16-46 PC, and tonite I played JPIII. I think the sub bottomed out on scene 12, just when the huge dinosoar attacks. I heard a sharp, deep clack or smack, and it came from the corner where the SVS is located. I'm wondering if this is a particularly taxing scene for a subwoofer, because I have not had a problem with the pod scene on Phantom Menace, U-571, SPR, etc. In fact, I was playing the movie at 7.5 db below my reference level of 75 db, and my subwoofer setting on my TAG pre-pro is already at -9.5 db, so it seems kind of strange that the sub would still bottom out. I tried it twice and it happened both times, but when I turned the volume down a little more, it did not bottom out. Has anyone else had a problem with their SVS handling this scene? Also, throughout the movie, there was crackling sound coming from the main speakers (M&K 150THX) on various scenes. When I played the movie through another system I have (M&K 750's), I could not hear any such sound. I have never heard this sound on any other DVD's. When I played parts of the movie again, it appears that only certain scenes have this problem. I assumed at first it was a bad DVD, but I don't understand why I only heard it on one system. Does anybody have an idea of what this crackling sound might be caused by?
