Having used a variety of subwoofers (many named above) with Quads ranging from the 57's to the ESL-63 to my current 2805's, nothing comes close to the Celestion 6000 subs. They are true dipoles and extremely fast. They go low enough for me, especially with the 2805's. I have always positioned them next to my Quads (on the inside/side) rather than putting my Quads on top which really doesn't work well with the larger Quads. Not sure how available they are and they're really heavy and so shipping costs would be high, although worth it!
Best Subwoofer for Quad 2805 under $5k
Looking for musical subwoofer for 2 channel listening (Not home theatre!) that has the speed and finesse to keep up with Quad 2805s. Heard the Wilson Benesch Torus is an amazing combination, but don't want to spend $13k.
Thinking about the REL Gibralter G2 (carbon fiber driver) or the JL Audio Fathom f112. Has anybody tried these subs with the Quads? Any other thoughts?
