Need a "short list" of best Subwoofers for M.L.'s


Hello out there!

I'm looking for the best possible brand, size, etc. of subwoofer that would be the best "blend" to augment my Martin Logan Odyssey's. (Let's keep it to the "powered" category for simplicity's sake :)

Thanks to any & all!

it is funny that this thread would appear. i just heard the oddysys with the descent the other day. i thought it sounded wonderful. i think it may be my next video purchase , in the living room.
I would sugguest a Hsu Research VTF-2. I use one with Aerius I's. For the money its an outstanding subwoofer
I love my Entec SW-1s with both my Sequel 2s (before) and my CLSIIs and Soundlabs (now). I have not heard the RELs, but I prefer stereo subwoofers and they would be very expensive (and probably overdone) as pairs. I have heard a pair of Vandersteens with CLSIIzs and was not impressed (but I don't think any of the four speakers were well set up).
The power of a REL Stadium with the speed of a Strata, at a lower cost than either. Fantastic sub. The only thing it lacks is an advertising budget:)
