Which subwoofer?


I have a small room (10’x14’) and am wondering if a subwoofer would help. If so, which one?

I have Martin Logan electrostatic speakers with  8” powered 200 watt woofers and 8” passive radiators.  The bass is articulate, but not very deep. I am wondering if I could get more bass volume and depth without loosing detail with an additional subwoofer?
I have tried an 8” Velodyne, but could never integrate it with the Martin Logans so I sold it. 

The Martin Logans are powered by a 200 watt McIntosh receiver. 
Any thoughts?

I assume you listen Nearfield.
I have a 13' X 13' room and use three subs.
It works nicely because of the Nearfield listening method.

Also definitely recommend stereo subs.
GR Research has many planar loudspeaker owners (myself included) who have found musical happiness with any one of their subs. Look into the model F-12G, designed in collaboration with Danny Richie of GR Research (hence the "G" in the model designation).

If you are REALLY serious, and are up to a little DIY, the Rythmik/GR Research OB/Dipole Sub is THE sub for use with dipole loudspeakers. Details on the GRR website.
The REL looks interesting, but I have what is probably a stupid question. The REL t5x goes down to 32 hz and my Martin Logans go down to 34 hz. Will I notice the additional 2 hz of bass energy?

Thanks for your responses.
