Designed specifically for loudspeaker manufacturers and powered by proprietary switch-mode amplification, Powersoft describes its M-Force linear motor as ‘a true and complete paradigm shift from the traditional moving coil and cone’.
‘The approach to converting a signal from electrical to acoustic has not been fundamentally changed since the beginning of acoustic design, ‘ says Powersoft R&D Director, Claudio Lastrucci. ‘With M-Force we have created an alternative method of acoustic transduction, by combining the latest technologies in the domains of power amplification, magnetic materials and advanced real-time digital signal processing. The result is a device that considerably improves the electrical-to-acoustic conversion efficiency at a system level, allowing the true exploitation of the native qualities of switch-mode amplification. This approach brings many advantages – most significantly providing a flexibility and sound quality experience that will set a new standard in low-frequency speaker design’.
With a development cycle spanning more than four years, M-Force is currently being tested in the field in collaboration with a select group of loudspeaker manufactures and live sound engineers. The goal is to offer a ‘system orientated’ package for selected loudspeaker manufacturers to produce unsurpassed low-frequency performance.
M-Force requires less power from the amplifier to produce a higher SPLs with extremely low levels of distortion than conventional transducers. Unlike conventional loudspeakers, M-Force is a genuine push-pull engine where the magnetic field interacts in a linear fashion to provide a controlled force to the moving elements. The transducer is completely free of moving electrical conductors, which maximises the efficiency and reliability of the system. The extremely high motor strength (typically one order of magnitude above conventional technologies) claims to offer a natural, controlled sound and negligible power compression at the highest sound levels. The extreme displacement capabilities allow an increase in SPL in function of the size ratio of the cabinet design. By merging the parameters of the transducer and the amplifier output stage, Powersoft believes the system to provide unsurpassed sonic performance and efficiency.
M-Force integrates with other technologies developed by Powersoft such as Differential Pressure Control (DPC) already used in subwoofers using IPAL technology. Offering high power efficiency, an extended lifespan and with low Neodymium content, it also aligns with Powersoft’s Green Audio Power philosophy.
