sub to match martin logans

Any advice regarding which subwoofer might best match martin logan quest z's, logos center? Have been told that Paradigm Ref 15 is best match for music (my main focus) and home theater. Also have heard that genesis 900 and muse 18 are good matches.
I have a Janis #W1 subwoofer with separate amp and crossover in oak veneer for sale, excellent condition, e-mail
A continuously variable phase control is as important as one for the crossover frequency.
well, my friend uses imf monitor IIIs Xed @ 40 w/krohn-heit filters w/ his re-quests. carl mentioned the phase contol, if i remeber correctly, muse had skubs with that control,which i always tjpught was the right direction to go. ive seen muse electronics at brooks berdan but never asked about the woofs.
I have the same 3 MLs & have had excellent results with a REL StadiumII.Personally I have reservations about the ability of 12 inch or larger woofers to keep up with the speed of the electrostatic panels. The REL with a 10 inch will keep pace & give you response down to 18HZ.
