Thanks for the info so far. No, I haven't purchased anything as of yet. I guess I should re-phrase my question - what subwoofer would you recommend for use with the Maggie 3.5R's? I had considered going back to a dynamic speaker but I just can't find one that I like having had the maggies for such a long time. I'm looking to supplement the bottom end - this would be for critical two channel listening - not a home theater application. Thanks again for your suggestions.
