My woofer won't stop barking...


I am using a new Earthquake SuperNova MKIV 10" subwoofer driven by the Sub Out from my H-K Signature 2.0 pre/pro. I am using a decent quality 25' RCA cable to connect from the pre/pro to the sub. My main speakers are Paradigm Studio 80s, fairly large floorstanders.

If I turn up the volume on the sub even a little bit (10% or more of total excursion of the pot) it constantly "growls". Changing the phase or cutoff freq. do not change this behavior. I can clearly hear the sub during quiet passages in music or movies, surely this is not right.

Is this indicative of a problem with the Sub Out on my pre/pro? Anybody know how to fix this problem?

Thx,

i have a barking sub when i use it with my HK,also center ch. makes a barking sound too,,i just figured my HK to blame,,will take it to get fixed sooner or later,im listening in 2ch mode now,,,
It could very well be RFI/EM noise being picked up by the long I/C. I would try a low noise shielded A/V cable made for subs along with the Y-adapter.
Rlwainwright, the "Y" cable is to be used if you don't have a spare main out. You can split the main outs and send one pair to the sub and the other to the amp. If you have a spare main out you don't need the "y" cables.
Try unhooking your CATV. If it is pluged into your VCR or TV or cable box it can affect any equipment in your system. If there is a grounding problem (which there often is) it will show up in your subwoofer. Mondial Magic will take care of this 95% of the time.

Good luck!
