Hello all, I was wondering if I could get some tips on choosing and setting up a subwoofer to integrate with my Quad electrostatics. I have included an in room response curve I plotted after following a great guide I found here. I want a sub mainly for music and secondarily for HT (HT not a big concern to me). These speakers seem to roll off quite sharply below 45Hz. I have been looking at a Rel Strata or possibly a Velodyne DD-10 (maybe DD-12). I have just moved on from a SVS PB12+ which was excellent for HT but was not satisfying me musically. Thanks for your input. Happy festive season, Rift.
