Martin Logan BalancedForce 210 Subwoofer - 850 Watt (1700 peak) Amplifier [Expired]

no longer for sale

Adding a subwoofer for movies adds a spectacular dimension.  Adding a subwoofer for a high-end music system usually causes distracting issues and can be difficult to blend properly.  Enter the BalancedForce 210.  Dual high excursion, hi-power 10' cast basket drivers are controlled by a massive 850 watt amplifier capable of outputting up to 1700 watts during peak demands.  Not only can the 210 produce bass to the extremity of human hearing, but its super fast and responsive providing hi-resolution low frequencies without the distracting boominess.

These are designed to mate with larger and very challenging electrostatic panels, but they work even better with traditional dynamic cone loudspeakers.  Prepare to experience and feel the entire range of human low frequency perception.

These are very well cared for by the original owner and in overall excellent condition.  Both drivers are in great shape and the cabinets are clean.  Being high gloss piano black there are some minor swirls and scuffs from cleaning, and one small ding, which you have to search for to even find.
