By PSW Staff • April 10, 2018 Powersoft M-Force At this year’s Prolight + Sound show, Powersoft (Hall 3.1 C17) is showcasing a new version of M-Force (announced as M-Force 301P01), a unique transducer that’s been updated with a series of additional features intended to simplify the workload of OEM partners. Specifically, M-Force is now available as the M-Force 01 long-throw linear motor for infra sub applications and the M-Force 02 short-throw linear motor for high acceleration applications. With longer linear displacement, M-Force 01 is designed for direct radiation and bandpass applications, helping to minimize cabinet sizes while delivering infra-bass reproduction. M-Force 02 is designed to grant reliability under extreme loads, such as bandpass applications and loaded horn configurations. Based on a patented, moving magnet, linear motor structure, M-Force is engineered to utilize all available power granted by switching mode amplifiers to deliver very high performance in terms of power handling, electromagnetic conversion, reliability and maximum sound pressure levels (SPL). It generates linear movement with parallel moving magnets. M-Force 301P01 is engineered in a factory assembled package, to simplify implementation. The motor is matched to a purpose-built diaphragm through a newly designed coupling and a lightweight chassis, which is also intended to improve thermal dissipation. The need for an external spring has also been negated because magnetic spring action from linear movement is delivered by motor and magnets alone. Claudio Lastrucci, Powersoft R&D director, states, “I’ve always considered power amplification, signal processing, and transducer design in loudspeaker to be one single entity in the pursuit of performance. There’s no division between one domain and another because this would limit the evolution of the products to small changes that don’t add up.” M-Force is configurable as a full system, comprised of M-Drive that fully exploits the potential of M-Force to use all of the available power granted by switching mode amplifiers. M-Drive can be equipped with any Powersoft or third-party DSP platform, and integrates Differential Pressure Control Sensor technology (DPC) used in both IPAL and M-Force systems. Powersoft’s patented DPC allows a differential pressure signal, acoustically obtained from the two sides of the moving loudspeaker membrane, to be fed to the amplifier just as any other electrical feedback signal. In turn, Powersoft’s Zero Latency DSP provides an architecture that ensures a stated 10μs latency on the critical feedback paths. Each element of the M-Force system, as well as every OEM product from Powersoft, is configurable with the Armonía ProManager dedicated software tool. With it, OEM manufacturers can initialize the system so that it shows proprietary brand information in Armonía, including series and model name, image and the serial number of the product. M-Force is already in use in numerous applications, including a large subwoofer installation at the Avalon nightclub (Los Angeles), and has been instrumental for concerts and tours (Red Hot Chili Peppers, Caparezza), music festivals (Ultra Miami, Raumarock, Helsinki Pride), as well as global events such as the Super Bowl and the Grammy Awards. It is also used in cinema applications while in Iceland, M-Force recreates earthquake movements in the LAVA Centre.
