Summary:
Up for sale is a Martin Logan BalancedForce 212 subwoofer in gloss black, serial number ACV9100272H07, in very good condition and complete with the original box. A reference-grade, large-format sub, the BalancedForce 212 uses two opposing 12" aluminum-cone woofers in a sealed cabinet, mounted so their reaction forces cancel out, delivering tight, deep, and remarkably clean bass with virtually no cabinet vibration. Dual 850W Class-D amplifiers, extension down to 18Hz, and a built-in 25Hz level control give it the headroom and flexibility to anchor both critical two-channel music systems and full home theater setups. Balanced XLR, RCA, and speaker-level inputs allow simultaneous stereo and LFE connections, each with independent crossover and level settings, while USB connectivity supports custom low-pass filters and room correction with the optional Perfect Bass Kit. A true no-compromise subwoofer for anyone chasing deep, fast, and accurate low-frequency performance. Shows some signs of use consistent with very good condition, but performs at full capability.
