If something can go wrong, I'm usually the one to find it....
This clicking occurs at low level. I never did get to the point where I could try this sub, as I couldn't adjust channel level. I unplugged this sub, as I smelt a burnt odor. Haven't done anything since.
The second sub is rattling. Only noticeable with the test tone. Does appear to rattle under normal operation.
I'm not apposed to pulling out drivers or the amps to look for something loose. The sub with the fragrance of something burnt has me more concerned than the one rattling.
I'm also wondering if this Denon might be part of the problem? Seams a bit weird the V2 500's had no issues, ever, and now both of the V4's do.
I did not get a call back from Axiom this weekend. I take it that tech support hours have been scaled back? If so, you all might want to consider advertising that, so folks with issues no when not to expect a call back. Some of us are busy people.
