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,

Thanks for all the responses, folks, they are greatly appreciated. Since I'm a cheap bastid, I will commence to un-plugging the cable tonite and see what that brings.

I am also wondering if not using a subwoofer-specific RCA cable could be part of the problem. Anyone have any thoughts on that?

Thx,

>> Try using the main outs with a "y" cable if neccesary. <<

Okay, I'll check tonite to see if I have a spare Main Out to do this.

>> You aren't using the processor xover and the sub xover at the same time are you? <<

I'm not sure if this is true or not. The H-K allows me to specify the size of the main/center/surround speakers to Large or Small. The mains are set to Large and the rest are set to Small. There is also a setting for Subwoofer On/Off, obviously I have it set to On. In addition, there is a setting for Subwoofer Trim, specified in + or - db, I have it set to 0db.

The subwoofer allows me to set Level (from 8 o'clock to 4 o'clock), I have it set at approx. 10 o'clock. Phase is set at 0 deg., the other choice is 180 deg. The lowpass filter (24 db per octave) is variable from 40 - 160 Hz, I have it set at approx. 60 Hz.
