SVS Subwoofers for music?


How good are the SVS subwoofers the cylinder series compared to the REL B3, Martin Logan Depth & Dynaudio sub 350 for music? The SVS seem to be a great value. My room is small 11x15x8. Thanks for any input.
System:
Dynaudio Focus 140's
Plinius 9200
Naim CDP 5i-2
For Movies NAD receiver T762
All FMS cables.

I have a SB12-Plus in my office.

I found my friend's REL B3 in his home to be much more impressive.

The small size and price of the SB12-Plus was attractive.
Thanks for your responses. Bob, could you please post your impressions if you follow through with the purchase? Thanks,
-Bill
