My Klipsch Sub-12 which I've had for about 6 years died. I realized it is the amp that is blown, which can be a problem with this amp. Klipsch states that I can replace the amp for about $200 with shipping, handling and tax. On the other hand, I have heard great news about the Cadence CSX Mark II. I also realized that it is on sale for $280 with shipping and tax. Meaning for $80 more I could get a new sub (better?). I should mention I am interested in any other subwoofers, for less than $500 with shipping and Tax.
My setup includes Klipsch (2) F-3 Towers, a C3 center, and (2) S3 surrounds. These speakers are all hooked up to my Pioneer Elite VSX-50 receiver and the primary source is my PS3 for Blu-rays and UV movies. My room has normal 10 foot ceilings The room is 14 feet long (11 feet to the listening area) and 15 feet wide. I should mention the right hand side of the room opens to another room which is another 10 feet wide (or total width of 25').
As far as listening preferences I listen to mostly movies (high action and suspense). I will rarely listen to music, but my wife does listen to it occasionally (5-10%). Her music tastes would include country and music like Mumford and Sons, as well as some Jazz.
I hope this is enough information to help me make a wise decision.
