Hello,
I have a pair of Epic CF-4 speakers (version 2) and one of the woofers in each speaker seems to be bad. At low frequencies it rattles a lot. I switch the bad woofers to the same cabinet then did a low frequency test from 5hz to 100hz and the good cabinet does not rattle at all and it produces clean bass. The bad one rattles and sounds like a helicopter taking off when doing the bass test. Where can I get a replacement woofer (two of them)? The part # is k-30-kn
Thanks,
Christopher
