Best REL Subwoofer for Magnepan 3.6's


I am considering trying a subwoofer with my Magnepan 3'6's. The REL subwoofers seem to be highly praised and there is a decent supply of used ones available. What are you recommendations for the best REL to try? My room is fairly large at 17w x 26L x 9h.

REL B series is what you want. I have the B2 in my HT and it blends in very well with my Vienna Acoustic Haydns. The B2 sometimes find a place in my two channel setup for a nice change of bass.

One of the things I like about the REL is the control to blend and integrate the bass.

I agree with Chazz on planning for two RELs.

B1= 12" woofer
B2= 10" woofer
Thanks; the REL Storm looks very promising, even two used would not brake the bank and they just might move the 3.6's to sonic nirvana.
I would go for the Stadium, I started with one and now have 2. I saw a Stadium 11 here last week for $995, one of mine is just like it. I have mine starting to roll off at 25 Hz. I actually have a Storm also but haven't heard it yet as it was for sale by local pick up only in DC and I had a friend there pick it up for me. In your room the bigger ones would work better, my room is 35x13x7 and I have no trouble using 2. I have often heard the theory that your room has to be very large to reproduce 20 Hz but I think that this is simply not true, another case of theory being at odds with reality. When did you ever see room size specified in frequency response specs?
I use the James 1500, have had the 1200's in the past and they all worked very well with the 3.6. The Jl Audio are very good, probably better if set up properly. I have only heard one Rel sub, and thought it was too slow, and a bit fat. Probably not optimized. jallen
I have a large listing room also and use two Rel Storm IIIs. I have tried one sub many times for waf...it just isn't the same. It takes two to tango fast,tight and low!
