Martin Logan Balanced Force 210 with Calibration Mic ***PRICE REDUCED***

You are looking at a lightly used Martin Logan BalancedForce 210 subwoofer in glossy black with all original packaging and accessories.  I am also including the calibration mic with this purchase ($100 value).  Amazing subwoofers.  I have used several versions of the 210 and 212 in my 2 channel system. They blend seamlessly with any Martin Logan electrostatic speaker and can almost disappear in a room or mate up with other speakers with their calibration software.  The glossy black BF210 was going to be added to my theater but I decided that the 5 subwoofers in the space currently are good enough :) 

Thank you for your consideration and happy listening!

Ultimate Performance Subwoofers

Chances are you've read or heard at some time that adding a subwoofer to a system built around electrostatic speakers is nearly impossible. Although that's not necessarily true (and we have the subwoofers to prove it), the idea is grounded in experience. For many years subwoofers and electrostats did not blend very well. Turn on the sub and maybe you got the deeper, stronger bass you were looking for but that wonderful electrostatic snap and midrange clarity were, if not gone, now smeared and disconnected.

Our goal, when we began our first subwoofer project, was to deliver the good stuff — deep, tight, powerful bass — and none of the bad. We wanted to build subwoofers that, when combined with ultra-fast electrostatics or conventional cone speakers, would blend seamlessly to the very bottom of the frequency extreme. BalancedForce subwoofers are the full realization of years of engineering by the MartinLogan team combined with the latest innovations in advanced digital signal processing, amplification, electrical system designs, and room correction.
