ACTIVE SUBWOOFER MARTIN LOGAN BF212
Top model of the new proposal Martin Logan for bass and extreme bass reproduction in all types of music and audiovisual reproduction systems, the BalancedForce 212 is a robust, elegant and powerful subwoofer that combines the most advanced electro-acoustic technology of the legendary American firm with a sophisticated amplification system with DSP control and, if the user wishes, a versatile room correction scheme (PBK) available as an option. The key to the BalancedForce concept is the use of two very low distortion woofers and high power magnetic motor mounted in a special configuration: exactly opposed to each other and operating in phase. The speaker cones used - each 305 mm in diameter - are a fundamental element of the scheme developed by Martin Logan positions ensure the absence of coloration and the displacement without deformation required to reproduce with maximum depth and precision the lower octaves of the spectrum. In addition, an airtight enclosure with non-parallel side panels is used to facilitate its tonal neutrality, while the amplification electronics is a state-of-the-art design that operates in an ultra-efficient version of the Class D operating principle. Of this amplifier it is worth noting that the combined use of low-noise, high-power transformers, a high-quality MOSFET transistor-based switching power supply, noise-canceling circuitry, and precise control subsystems enables it to handle large amounts of current with little or no distortion. Finally, the BalancedForce 212 includes line (stereo, LFE) and high-level (box connection terminals) jacks, as well as a 12 V trigger signal. A USB port makes it easy to connect a room correction system. (optional) PBK and the 25 Hz trim control Martin Logan to tailor the subwoofer response to the listening room. In short, a careful and seductive product created for the most demanding fans.
