Thanks for the recommendations. Rythmik is actually one other I have heard is a good match. I use Quicksilver V4's with a high output pre and really enjoy it. I was leaning to Rel only because it played from the amps signal and not from an output from the pre. I will look into it, but you have helped point me in the right direction, or avoid buying a HT sub or one that does not match well...thanks!
Rel subs with Magnepan 3.6's
What Rel subs (I plan on buying 2) on a budget work well for 2 channel using Magnepan 3.6's? My room is roughly 14x35 with my system on the long wall. The ONLY other sub I am considering is SVS SB2000. However strongly leaning towards Rel as they hook up to the amps, so better synergy. Thanks for any input!
