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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eWe do take trade-ins, so please contact us if you wish to do so.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease make sure to thoroughly inspect item photos for cosmetic condition.  We do try to describe the item as accurately as possible, so if you have any questions about cosmetic condition please message us.\u003c\/strong\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"Martin Logan","offers":[{"title":"Default Title","offer_id":67940554473532,"sku":null,"price":2995.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0610\/9573\/9452\/files\/IMG_1583.jpg?v=1794113943","url":"https:\/\/3maaudio.com\/products\/martin-logan-212-balanced-force-subwoofer-in-gloss-black-w-box-serial-acv9100272h07-very-good","provider":"3mA High End Audio","version":"1.0","type":"link"}
