I have Paradigm monitor 11s for the front with a Paradigm cc-350 for the center. For the rears I am using mini-monitors. My sub is a Klipsch KSW-12 which I have set all the way up to 120. I calibrated all the speakers, including the sub at 75 db.

hi mstmorse,

just a checklist:
1.) did you switch to c-weighting to calibrate the sub?
2.) as KCB suggested, try phase adjustment on the sub.
3.) the monitor 11's are rated to (+/- 2db) 40hz, so try the x-over at 40 for the mains and set your sub x-over to 60hz and adjust it from there.
4.) is it the same sub you used with the yamaha? if so, is it the same placement? you could try the simplest placement technique i know of. place the sub in the listening position, then crawl around the room with bass material playing until you find the location where the low end sounds best. place the sub there. barring more involved and expensive measures, you should have the optimum set-up at this point.
5.) the easiest way to compare though, is to set your speakers to large the same as you did with the yamaha in which case, depending on the source material and where the sub's x-over was set, you may have experienced double bass, or a bump at around 45hz and may have become used to hearing it as normal.
(am not familiar with the yamaha, just a guess).

jimr: i personally think of hsu as one of the few guys who gets it. i'm curious...did your sub come with a recommendation as to where generally to set the x-over?
