The receiver is a new Denon X4300H. Audyssey set both trims at -9. I'm not sure if that answers your question about receiving a hot signal from the AVR. I described the problem to PSA when I first noticed it. They sent me a replacement woofer which I already installed. The problem is much less than it was, but unless the audio was badly clipped, I wouldn't expect any bad noises from the subs at -8 MV and only running them a few dB hot at the AVR. With 2 good subs in a med/large room, I should be able to crank them pretty hard before hearing any break up. I did notice a small "pop" each during a scene of The Force Awakens and 13 Hours last night (forget what scenes). Since the other sub is fine, I still wonder if something is amiss with the V1500. I just wanted to know everything I could before contacting PSA again. Other than the beginning of Edge of Tomorrow, are there any particular scenes that would be a good test for whether the sub is acting normal or not? Can I assume that I should be able to run reference volume with no sub boost (leave the trims where Audyssey set them at -9) without problems if everything is OK with the subs?
