I agree that those speakers deserve a musical sub. I am a REL fan and own a Storm III, but I would suggest you check the ACI Force. I believe it's on sale now but since ACI is upgrading the looks of their subs, I would wait for the new Force XL, which should be out this month (I can't find the Force XL picture on their site, but if you email me, val at dorta dot com, I will send it to you). The Force is as musical as a REL (very similar to the famous Strata III) and almost as easy to setup, and on top of that is a real bargain in today's audio, starting at $750 each. I will put together mouth and money by buying one soon.
