Best Subwoofer for B&W 805s Speakers


As many might know the B&W 805s speakers lack bass and I am trying to find a subwoofer under $1000 that would integrate well these speakers. I've been doing a lot of research on the web and there are too many choices out there (SVS, HSU, AV123, EPIK...) and I can't seem to decide. This is srictly for a 2 channel stereo system so no HT. My Equipment is all Rotel. Any suggestions? Thanks.

REL Storm III @ $900 to $1,000 on the used market. Very musical with a seamless presentation... offering a high degree of flexibility as far as connection options and adjustability. I had previously owned four other subs, including two from Velodyne, one from Atlantic Technologies and an old Yamaha sub, and the REL bested them all by a wide margin.

I would have never sold my REL, except for the fact that my Dynaudio C4's don't need a subwoofer, and I plan on keeping them for a long while, and I used the proceeds from the sub for some NOS tubes. If I'm ever in the need for another sub, REL would be at the top of my list.

Thanks, I'll keep the REL in mind, I know they are very musical since this is at the top end of my budget I was wondering if anyone has had any experience/good results with something a even less costly?
The B&W ASW610 (retails for $1000) gets high marks from Stereophile. Used, you may alos look at Velodynes SPL series.
Consider the REL T series. I have just added a T-2 to my system with excellent results. There is a T-1 listed today .
