ACTIVE SUBWOOFER MARTIN LOGAN BF210
The starting point of the new and exclusive proposal of Martin Logan for bass and extreme bass reproduction in all types of music and audiovisual reproduction systems, the BalancedForce 210 is a compact, elegant and powerful subwoofer that combines cutting-edge electro-acoustic technology from the legendary American firm with a sophisticated amplification system with control by DSP and, if the user wishes, an effective room correction scheme (PBK) available optionally. 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 with a diameter of 254 mm - 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, let us highlight that the BalancedForce 210 includes line (stereo, LFE) and high level (connection terminals to boxes) jacks, as well as a 12 V trigger signal. A USB port facilitates the connection of correction system of rooms (optional) PBK and the adjustment control to 25 Hz of Martin Logan to tailor the subwoofer response to the listening room. Without a doubt, the perfect compromise between practical imperatives and engineering excellence.
