Your Maggies will sound better, for sure, with a sub. I shopped, listened, compared may subs and wound up with the Sunfire Architectural sub. Designed for two channel listening. Front firing woofer. It's a crying shame you don't hear about this sub, enough, on the 'gon. Fast, tight, great extension, small, and very powerful. A jazzman's delight. They have the Architectural Signature, too. 12" rather than 10" woofer. Can be found nicely discounted. Lists for $1400. I love mine. happy hunting. warren
