Axiom Home Page Forums General Discussion Home Theater very little sound coming from subwoofer

I have talked to one of the experts at Axiom audio and we ruled out that their is something wrong with the receiver (hardware issue?) and not the subwoofer.

We connected the coxial to one of the analog outputs of the DVD to the subwoofer line in, and that was plenty of bass. But the quality of the bass was poor [rumbling (but this is because I connect the coxial to the analog, and not the sub pre out of the receiver)].

The humming only comes when I connect the sub with high level input and not the coxial which I intend to use.

Only problem is it testing my speakers and sub with a new receiver.

Thanks guys for the useful info!
