Marantz 2235 + Epi 100v's = Problemo..help?

[soma89]

Hey guys,
I just bought a Marantz 2235 and a pair of Epi 100v's. I've noticed that when the bass or volume is set past halfay the left speaker woofer would just go crazy and vibrate violently. This only happens when I'm on phono. It doesn't happen at all when I listen to the radio through the receiver.

Anyone know what the problem could be here?

Thanks

acoustic feedback?

Speaker may have an air leak, how's the foam doing?

Record warp, you probably need a subsonic filter.

If it was acoustic feed back it would be doing it on both speakers.
