Axiom Home Page Forums General Discussion Technical Questions EP500 Popping?

Yes bolt148. Your experience with the newer EP500 version has been consistent of individuals that have received the newer EP500 units with the re-designed amp. I hope axiom looks into this issue further. The newer amps they have designed don't seem to live up to the previous version. I would be hesitant to recommend them.

I will try that.

I thought that the built in Audyssey room correction on my NAD T747 would fix that issue?

I have noticed that the bass changes as I move throughout the room, but I was under the impression that the receiver equalizes the sub to get the best response at the current seating position.

There is nothing you can do to equalize a null because anything you apply to the signal applies equally to the out of phase wave as well.

Audyssey is a not a fix all, it only attempts to equalize what it can within it's somewhat limited range and if the Audyssey you are using is an older version, it may well be killing the sub to equalize the room. Try running the system without Audyssey.

To further the idea of moving a sub. I found that simply rotating the sub within it's normal spot can help with the way it sounds. I went from straight out 90deg. from the wall, to facing the opposite wall at 45 deg., to firing directly into the side of the couch which was the best sounding placement.
