Martin Logan Balanced Force 210 Subwooer Includes Perfect Bass Kit

This is an exceptional subwoofer. It has two10-inch high-excursion, aluminum cone woofers powered by 850 watts (1,700 watts peak) amplifier. Previously in my system I had a Velodyne DD 10+, a pair of JL Audio subs and then this Balanced Force 210, which far out shown the previous units. It will put out a great bottom end and blend extremely well with your speakers. If you own ML Electrostatic speakers, you can download a filter to provide a seamless transition with the crossover. Also included is the ML Perfect Bass Kit ($100.00) which includes software and a microphone to enable you to correctly set up this subwoofer for the best performance, as well as 4 brass cone/spike decoupling gliders from Herbie's Audio Lab, which will enable sliding the subwoofer easily on carpet to assist with positioning.

The top is a beautiful dark cherry finish, with some swirls in the glossy finish that are not visible unless you angel light right onto the top. The front of the cabinet is a high gloss black. The grill covers are in excellent condition without any picks or marks. It is conservatively rated 8/10.

I have sold my entire system except for this subwoofer and a pair of ML Spire speakers that are for sale as well. Includes manual, and ship in original factory boxes.
