MartinLogan Balanceforce 210. This is one beast of a subwoofer. Built in 850 watt amp, with 1,700 peak response drives 2 10 woofers for a truly mindblowing experience. Package this in a beautiful cherry finish cabinet and it stands out as a true statement piece with any audio lovers room. Adds earth shaking effects to any home theater. Sadly have to part with as my wife and I have downsized and a sub of this size needs space to truly shine. Rather than put all the specs here, take a look on line for details on this piece. I used this mainly in my home theater. Packaged in original carton, this isnt your lightweight hide behind furniture sub. Package weight is a hefty 120 lbs so its going to cost a bit depending on where you live. Pickup is always an option for a buyer living in the New England area.
