Best Subwoofers? for my system


What are the best subwoofers to use with my system? I want to use two subs. My fronts are Aerial 7B's, center is Aerial CC3B. As soon as funds allow, I will be adding another set of 7B's for surrounds (& later another set for side surrounds).

I want something musical even if it doesn't have that last bit of impact when watching movies. I have heard very good things about REL & also the Aerial SW-12 sub.

Present System
Amps - (2) KAV-250a's & (1) KAV250a/3
Processor - Krell HTS (will be changing, Lexicon? Theta?)
DVD - Temporarily a "mid-fi" Pioneer (will also change)
CD - Classe CDP-1

Thanks in advance for your suggestions.

HI Jeff
I used to have two Rel Storm Subs in a two channel set up, because one sounded thin and uneven. I have since upgraded to one Talon Audio Rock 2002 and have been extremely happy since. You should do a demo if you could. The bass from the Rock is tight fast and full of body, texture and timbre.
I am not a dealer and I also do not work for Talon. I hope this helps.
I've been very happy with my two Velodyne HGS-15 subwoofers. I would highly recommend a listen.
As a fan of Aerial, I would think the Aerial SW12 would be an excellent match for the 7b's.
I have two Aerial SW12s in my system and I have no desire to look further. They are powerful, very clean, and musical. Even with all they offer it was a challenge to integrate them with my LR5s and CC5 but I'm very happy as is.

Thanks everybody,
Sugarbrie, adding another crossover via the high pass speaker terminals in front of my main speakers concerns me even though I'm sure it is of very high quality. Have you tried this set up? I don't have the space to have separate music & home theater systems so one model sub (in a matched pair)will have to do it all.
