In 1995 Powersoft successfully introduced Pulse Width Modulation (PWM) technology in a way that enabled amplifiers to achieve a previously unthinkable level of efficiency and power, with Power Factor Correction (PFC) technology integrated into switching mode power supplies. This technology was gradually adopted in professional audio applications worldwide due to its extremely high efficiency, which enables it to transform all the energy drawn from the mains into usable power and recycle the reactive energy coming back from the loudspeakers (back EMF energy recovery).

By combining the company’s knowledge of switch-mode amplifiers, the desire to fully exploit the real benefits of the native energy recycling capabilities and the latest magnetic materials, Powersoft changed the approach to converting a signal from electrical to acoustic, which had not been changed since the beginning of acoustic design, and introduce the M-Force a new electrodynamic device that considerably improves electrical to acoustical conversion efficiency, sound quality, robustness and power handling.
