Given the equipment you own, I'd surmise that reproducing the essence of the recorded music is a high priority for you. Hence, think about subwoofers that are noted for their musicality as well as their ability to cleanly reproduce the lower frequencies, and for their ability to integrate seamlessly with the rest of your system.
With those two criteria in mind, the Vandersteen 2Wq subwoofer should definitely be on your short list. Used units often sell here on Audiogon for $800-950.
You might want to do a search of Audiogon's archives to look at the many articles that have been posted about subowoofers, including the summaries of articles about subs taken from a number of audio mags. If you do so, you will note that 4-5 subwoofers consistently rank near the top, with the Vandy 2Wq being one of them.
