Arthur. What are you going to be listening to on this setup? If its music only, you don't need to spend as much on a sub. Most music is above 40Hz, even the bass. Exceptions to this are pipe organ, synth, and a few classical music instruments.

I am sure you can find a sub quality in the $400 range that will reach into the upper 30s.
