Nasty problem - ideas?


On two occasions now, during a movie, I've heard a sharp, unpleasant 'snap' through the right channel (or sub, which is on the right?) during dynamic passages. I haven't heard it on 2 channel only, even at high volume. On the one hand, to narrow down the source requires having it happen repeatedly, but it's an ugly sound, and I'd rather not have it keep happening and potentially damaging something, so I thought I'd post here to see if any of you have experienced something similar.
Nothing in the system changes between 2 channel and HT, although the sub is obviously worked harder during HT, and last night I heard it during Olympus Has Fallen when the C130 was going down (for those of you who've seen the movie). Maybe the volume was a little high, the wife thought we were having an earthquake ;)

Anyway, thanks for any input. It's a sharp 'SNAP' that is either a tweeter, or something electrical in the sub amp at first thought.

Ok, thanks, I'll retry the same passage with the sub turned down - it was impressive, but didn't seem too loud. Maybe it was too much. Thanks.
Ok, thanks all. I checked the volume on the sub, and it was at about '10 o'clock', so I turned it down a little, replayed the passage I remember having the problem on, and it didn't happen. I'll check the woofer travel tonight when I get home, and verify it's possible. It is a sharp, high-pitched 'snap', not unlike your description of a rimshot.
Pbnaudio - I did that check on the sub, and it did bottom out in travel before it touched anything in the back. I'll do some more checking/investigating....
OK, also worth a look. I must admit, I don't trust the YPAO, but don't have another system for EQ'ing the system/room. I have just adjusted everything to 'flat', and input my measurements to each speaker, and it seems ok. I dialed back the sub volume, and haven't had a recurrence yet....
