The starting point of Martin Logan 's new and exclusive proposal for bass and extreme bass reproduction in all types of musical and audiovisual reproduction systems, the BalancedForce 210 is a compact, elegant and powerful subwoofer that combines cutting-edge electroacoustic technology from the legendary American firm with a sophisticated amplification system with DSP control and, if the user so desires, 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 opposite each other and operating in phase. The speaker cones used – each 254 mm in diameter – are a fundamental element of the scheme developed by Martin Logan since they ensure the absence of coloration and the displacement without deformations required to reproduce the lower octaves of the spectrum with maximum depth and precision. .
Likewise, a hermetic enclosure is used with non-parallel side panels that facilitate its tonal neutrality, while the amplification electronics are a state-of-the-art design that operates on an ultra-efficient version of the Class D operating principle. This amplifier should be highlighted. That the combined use of low-noise, high-power transformers, a switching power supply based on high-quality MOSFET transistors, noise cancellation circuitry and precise control subsystems allows it to handle large amounts of current with almost no distortion. Finally, let's highlight that the BalancedForce 210 includes line (stereo, LFE) and high level jacks (connection terminals to boxes), as well as for a 12 V trigger signal. A USB port facilitates the connection of a correction system (optional) PBK room control and Martin Logan 's 25Hz tuning control to tailor the subwoofer's response to the listening room. Without a doubt, the perfect compromise between practical imperatives and engineering excellence.
