I have had my EP500 for five years now, never had an issue with it. It actually works a little too good. I would love to get a 2nd one, but it fills my 16' x 24' x 9' dedicated HT room with so much clean, tight, musical bass, my wife won't let me, she doesn't see a need, and frankly, I am not necessarly conviced it would make that much difference either. I have never regretted any Axiom purchase, but the EP500 is always a topic of conversation when I have friends over.
I can't imagine what a 600, 800 or even multpiles of these sub woofers would be like in my room. But I guess everything is relative.
