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.

One thing i've noticed with subwoofers.  there are two types of listeners:  those adding subs just to make the bass natural--the way it was recorded.  And then there are those who want more bass than is recorded on the track.  I'm not criticizing anyone but these discussions go sideways as the two different crowds have 2 different answers.  It is good to define which you are.

@phusis So do you consider the bone-shaking thump of a dance club or the bass in the car next to you at a stop light that shakes your car "natural"?
