Comparison of various subwoofers for 2 channel audio


I have a 2 channel audio system, and I appreciate how subwoofers have augmented the sound quality of my system (with electrostatic speakers).  I currently am using a pair of Martin Logan Balanced Force 212 subwoofers, but I’m thinking about adding more subwoofers for a total of four in order to help balance the low frequency sound waves.  I’m considering adding a pair of Rythmik, SVS, or perhaps Velodyne subwoofers to the system.  Does anyone have experience with many of those brands, and how well they integrate with electrostatic speakers in a 2 channel system, or perhaps should I just get a second pair custom built with certain specifications?  
Thanks.

I use 4 subs in a distributed bass array (swarm) and have never had better low frequency reproduction.

From what I have read, the integration of the subs is more a result of the interface/crossover and less about the brand of sub used. I have 3 Rel's and 1 SVS.

I use a MiniDsp 2 x 4 HD to set the crossover for individual subs.
