Powersoft Roadshow Demonstrates New M-System Subwoofer Technology

System designers/integrators and live sound personnel learn about company's next generation Class D amplifiers and moving magnet linear technology

Powersoft recently held four in-person listening sessions entitled “Xperience The Power” in Los Angeles and San Francisco—attended by system designers and integrators as well as touring and rental operators—to demonstrate the capability (and highlight the availability) of the next generation of its Class D amplifiers and moving magnet linear technology, which is called the M-System.

The M-System utilizes the company’s patented M-Force motor transducer, M-Drive switching mode amplifier module, and Differential Pressure Control (DPC) technology to be able to produce a stated 150 dB SPL from a single cabinet.

“M-Force represents the pinnacle of all of Powersoft’s engineering developments that have transpired over the last 20 years,” says Paul Freudenberg, U.S. general manager, Powersoft. “There are limitations to the conventional amplifier and transducer model, and M-Force changes that paradigm with a specialized, purpose built linear motor and a specialized amplifier. The result is an unparalleled amount of force, power and sonic efficiency in a very small enclosure.”

Each of the presentations also included a demonstration of Powersoft’s other amplifier lines, including K Series and X Series, as well as Armonia software, which puts DSP and control capabilities in the hands of the user. In addition, the sessions focused on the overall advantages of Powersoft Class D amplification, including efficient power consumption, lower heat dissipation, and a smaller physical footprint, among others.

“This roadshow — which we expect will continue into 2016 — takes Powersoft’s message of performance and efficiency to companies that are at the top of their game in areas such as live sound providers, systems integrators and OEM manufacturers,” Freudenberg continues. “As Powersoft does not manufacture loudspeakers, this represents a vast opportunity for the market at large.” 

The M-System was a core component a huge subwoofer installation at Hollywood’s Avalon Sound earlier this year. The technology was also used for this year’s red carpet event at the Grammy Awards in Los Angeles, and is a nominee to receive a NAMM TEC (Technical Excellence & Creativity) Award, which will be announced at the 2016 NAMM Show in Anaheim this coming January.

Massimo Minardi, sales manager, OEM and M Systems, presented features of the M-System before playing a live audio demonstration, providing a reference point for those in attendance. Features of the M-Drive amp module include:

• The ability to recycle Back-EMF (Electro Motive Force) from the loudspeaker, improving damping efficiency and enabling power banking of energy.
• Very high power density and output.
• The ability to deliver high power and current at a very low impedance load.

Listening session attendee Brad Katz, system programmer at San Francisco-based JK Sound, states: “The M-Force is very exciting, and it’s nice to see such a breakthrough in driver technology. Coming from an install background, it’s very important to fit a lot of sub in a small footprint — this is key in the nightclub industry, for example.  The most compelling thing I saw at the demo is the passion that the Powersoft team has brought to the table — it’s very clear to me that this company is trying push the audio industry forward, and this is where it is at for me.”

Powersoft holds five patents on M-System, including two on M-Force, one on M-Drive, and two on DPC. Find out more about it here.
