Subwoofer Controls? Dual Volume Setting


I currently own a B&W ASW1000 subwoofer and use it in my home theater as well as for two channel music. The trouble I'm having is that I believe there should be different settings for HT vs. 2 channel music.

For example a perfect subwoofer setting for the Matrix would produce horrible results when listening to most music.

I know the B&W ASW4000 has separate LFE inputs and L/R Line Level inputs governed by separate volume controls for each.
Unfortunately, B&W does not provide this option on ANY of is's other subwoofers.

Does anyone have a fix for this? Is there a subwoofer control device of sorts which has separate inputs and would provide separate volume controls for LFE and L/R?

I have a Stentor II and I think it is rated to 17 hz. It shakes objects off of shelves. I know I am a minority but I have always thought the perfect sub was best for either audio or home theater. I like the realism you get in home theater with an audiophile sub. Boomy bass may make explosions sound better but it is at the cost of clarity.
I have a Velodyne HGS-12 and feel that it works very well for both audiophile and HT music. I have Proceed/Pass/Revel/NBS stuff. I have the sub sourced from the "Sub out" on the Proceed processor, which allows me to choose which channels the sub gets its sound from and what crossover freq to use.
imho, my humble pair of bridged adcom gfa-555's are better than the amplification in *any* powered subs. also, my marchand deluxe xm-9 crossover is better than the x-over in *any* active sub - more transparent *and* more flexible. combine these with subwoofers that don't try to alter the laws of physics (i like my vmps larger subs), and yule end up w/bass as good as yure gonna get, w/o blowing the budget. *real*, deep, textured, tight, accurate, un-distorted, hi-level (if/when ya want it), BASS...

i tried a retail $1500 rel (stratus? storm? - don't recall...), and for music, frankly, it was a joke, imo - one-note thump, & not wery deep, at that. mebbe two wooda worked better, but, then it wooda cost more than my present set-up, which except for one of the amps, was purchased brand-gnu...

My question wasn't "What is the best subwoofer?"
My Question IS, is there a control device which allows
for at least TWO inputs and TWO volume settings that
will work with ANY subwoofer?
