Subwoofer recommendations for this system?


I am in the process of seting up a new system:

Ah! Njoe Tjoeb 4000 CDP with all upgrades
Bottlehead Foreplay preamp
Wright Audio 2A3 monoblocks (3.5 watts)
Reimer McCullough speakers (+/-3db 42 to 20 khz, 94dB efficient)

Room size is 15x20 ft with a cathedral ceiling sloping from 10-18 ft, and opening into a very large and high hallway. I listen to many styles of music, but mostly jazz (both acoustic and electric). This room can quickly become "boomy" with too much volume or too much bass, but the Reimers alone do not provide enough low end.

I am looking for a very musical subwoofer that will fill in the lower octaves, and integrate seamlessly. There is no home theater requirement. Budget is $1000 max.

Thanks in advance

We have similar rooms and satellite speak efficiencies (Ref 3A de CAPOS- 92 dB). I recently added a SV Sub PC-Plus. I am very happy $750.00. If you go that route, tell them Robert Hart of Audio Tweakers sent you. No commission, just brownie points
Thanks to everyone for your suggestions. I called Rick Reimer (who built my speakers) to ask this same question, and he said he will build a subwoofer for me (tuned to match my speakers and using the same veneers for the cabinet). He does not advertise them on his website, but will custom build them for customers. And, his price was very reasonable!
I would want to know some details about any "custom" sub. Particularly the amplifier that will be used and what the warranty will be. Companies like REL and ACI use custom built, very high quality amplifiers that are extremely reliable. These would not be readily available. Many of the plate amps that are easily available are not particularly reliable or of very good sonic quality to begin with. Make sure you find out details of the amplifier used. I guess it just strikes me as odd that they don't advertise a sub but can just come up with one. It is entirely possible that they have a real good one available, I'd just want to know more specifics of amp- driver- tuning all that good stuff:)

I really spent a fair amount of time researching subs and auditioning them before I finally shelled out money. I found that I simply could not live with most of them. I also asked the various companies a lot of questions. One of my concerns was reliability. After all, if a subwoofer amp fails it can be a bit of a hassle, one I'd rather not have to deal with, or pay for. I've sure heard a lot of horror stories about certain plate amps and even certain models from the "big boys of subs". I just can't quite imagine throwing together a powered sub and having it be able to compete with designs from companies that have invested years into getting it right.
