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 use a Velodyne HGS-12. It is small, tight and has flat response down to 20htz. Very powerful but refined.
I second the Architectural Signature or just the plain ole Architectural, which is the one I own and love. Fast, tight, amazing extension: a two channel wonder of a sub. peace, warren
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.
