ACTIVE SUBWOOFER MARTIN LOGAN BF210
The starting point of Martin Logan's new and exclusive proposal 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 state-of-the-art electroacoustic technology from the legendary American firm with a sophisticated amplification system controlled by DSP and, if the user wishes, an effective 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 with a diameter of 254 mm - are a fundamental element of the scheme developed by Martin Logan, since they ensure the absence of coloration and the displacement without deformation required to reproduce the lower octaves of the spectrum with maximum depth and precision. .
In addition, an airtight enclosure is used with non-parallel side panels that facilitate its tonal neutrality, while the amplification electronics is a state-of-the-art design that works in an ultra-efficient version of the Class D operating principle. that the combined use of high-power, low-noise 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. To finish, let's highlight that the BalancedForce 210 includes line (stereo, LFE) and high-level jacks (connection terminals to boxes), as well as a 12 V trigger signal. A USB port facilitates the connection of the correction system. PBK (optional) and Martin Logan's 25Hz Trim control to tailor the subwoofer response to the listening room. Without a doubt, the perfect compromise between practical imperatives and engineering excellence.
