Subwoofer questions -- music only


I have a wonderful pair of Von Schweikert VR-1 standmount monitors that I currently augment with a single Martin Logan Abyss subwoofer. I'm curious about running a stereo sub configuration.

I'm not a bass freak, although I recognize the need for that octave below 60 Hz or so. I would like to hear what benefits stereo subwoofers might provide. I also don't have an unlimited budget. So . . . can anyone recommend a pair of subs at $1,000 or less that I might compare to my single Abyss? One choice would obviously be another Abyss. Is there something better at that price point? Again, I don't really care about pipe organ music, so a 10" sub would probably suffice, but I do need the ability to come off my amp OR my preamp. Thoughts? Thanks.

I used a single Velodyn Optimum 8 for several months.
I purchased a second and was very happy with the results.
I'm not a bass freak either, but the stereo bass was better in imaging and fullness. It just sounded better all the way around. More coherent. I thought the single sub was omni present until I put the second one in. Good luck in your venture.
I suppose I'm probably looking for a pair of sealed subs. Is the Optimum 8 sealed or ported? I would much prefer "tight" and "fast" over "deep" or "loud".
If you can stretch to $1149, this is reportedly a great value:

(Disclaimer: I've never heard these units, my "recommendation" is based on test results and the overall excellent reputation of SVS subwoofers.)

I truly feel you would have to get up pretty early in the morning to come close to the Vandersteen 2WQ Subwoofer Made right here in USA.
We have successfully blended these units in many different
rooms with all types of speakers from Magies to Monitor types.
The 2WQ is a sealed system which offers superb in room response, zero Bass hangover when compared to ported designs,and a Sophisticated high Pass that allows your whole system to achieve greater clarity realism and transparency.
