Which Sub Woofer is good for my 2 channel system


I want to add a Sub to my 2 channel music system and would like comments and suggestions on which one. My music room is 12 x 16 and I am using B&W 805 Sig's. If it matters my source is McIntosh 352 amp and the C2200 pre.
I do not like booming,rolling,load bass. Something, tight,fast,smooth.
Music choice is: Light Jazz,& Vocals.
My first thought was 12" or less. I use a sub in my HT system but that is NOT part of my 2 channel.
Budget amount, I would like to keep at 2000.00 or under for new sub.
Your suggestions would be appreciated.

I suggest you consider adding two passive subs and an active crossover. I am running a similar system to yours and would recomend this option. See my system for details.
I get remarkable performance from the archetectual signature matched with Revel M20s.
Well!!! I guess I have to decide between the Rel or the Sunfire. From what I found this might not be that easy to decide between, both are going to the top of my list for audition. I truly appreciate the comments on "which" sub to go with, Thank You.
I am curious as to why "Nrenter" would suggest,"even better go with 2" I would not have a problem with that, I just don't understand?
Thanks Again,
Dave
I've tried subs with B&W speakers before, only ending up taking the sub back to the store. Turns out that for music, I prefered the balance afforded by the full range speaker, even if the bass was a wee bit shy. My vote is NO sub with your great 805 Sigs.
