I alternate between KEF LS-50s and Magnepan .7s for my primary speakers. Most subs I've tried make low tones but they sound wooly, slow, and flabby compared to the primaries. The REL T/7x in my listening room is an incredibly good match for both speakers. Fast, well defined bass,with adequate dynamic range and output level in my situation. Bigger room, bigger speakers, obviously I would double up or go with a higher-end offering.
