Hello folks: I am in the process of upgrading my present subwoofer (M&K V75 Mark-II). Yesterday I picked up a Paradigm Servo 15 to demo for the weekend and to compare. I don't have the external XO for it, but I believe the gent said it was fixed at 100hz (??). I presently have my processor (Lexicon MC-1) set at 80hz. Optimally, is this the best setting for a demo of this sub...? With the MC-1, I can only go 40, 80 or 120.... would there be a potential risk factor setting it at 40 (listening to such things as TS2, Titan AE etc)...? So far, I am very impressed. It seems very transparent and certainly blends in with music much better than the M&K. Certainly "punchier" than I have been used to... BTW, I usually leave my speakers set to large. Secondly, I'd be interested in hearing any opinions as to alternative subs comparible to the Servo 15 in terms of specs and $$ that you would recommend over the Servo 15. I suspect the apples to apples comparison for Velodyne would their HGS 15.... which is twice the price. Is it twice the sub...? I can get the Paradigm new for about $1300 CAN (which is about $865.00 US $). Also, I would prefer to just have one sub. I have heard of a few DIY recommendations.... though not sure I have the confidence to go that route.... As for my room, it is approximately 14x23 with a cathedral ceiling - 8' up to 11.5' in the center. I have an 8' opening to the dining room at the rear of the HT. Carpeted throughout and 3" accoustic soundboards at the front of the room from the floor up to about 4' up the wall. So the room is well damped but not too dead. Also want to confirm that based on my room size, the subs I am considering (or ones you recommend) are adequate. Any help would be greatly appreciated. Thanks, Herb Kane. ------------------ System - Lexicon MC-1, Bryston 9B ST & 4B ST, Pioneer Elite DVD DV-05, Martin Logan (Ascents, Aerius i's, Scripts & Cinema), M&K 75 sub, Richard Grays 1200S, Sharp XV-Z1 projector & Da-Lite Cosmo screen.
