Hi...

I recently bought an EP400 subwoofer. It works great at low volumes. However, I'm experiencing a phenomenon that I don't quite like when listening at medium to higher volumes, and I'm not sure if this is standard/normal for this subwoofer.

When listening at medium to higher volumes of bass heavy tracks, I can hear the aluminum woofer rattle at a much higher pitch than the sub-frequencies that I expect a subwoofer to make. It's a rattling that is layered on top of the bass - when I hear that, it makes me kind of cringe, like trying to walk on a sprained ankle (the 1st metaphor that came to mind). I don't know if the subwoofer is damaged, or if i'm further damaging it by playing it at this level, or if this is part and parcel with subwoofer performance. I honestly don't feel like i'm 'cranking' the volume with it! And this is a subwoofer - not exactly a light parcel... I'd hate to think of the postage cost to send it back. (sigh)

Any words of wisdom out there?
