Powersoft "Xperience The Power" Showcases World's Most Powerful Subwoofer Technology: M-System

	Powersoft founder and research development director of Powersoft, Claudio Lastrucci, explains an M-Force 30" loudspeaker cone design.

Two weeks ago, Italian amplifier manufacturer Powersoft "shook things up" with four exclusive in-person listening sessions in Los Angeles and San Francisco. The company says the presentation and listening experience, which astounded an A-list of invitation-only attendees from live sound, systems integration, and loudspeaker manufacturing markets on the west coast, heralded the next generation of Powersoft's Class D amplifiers and moving magnet linear technology. After a thorough explanation on the science behind the technology, guests were treated to a room-shaking, ear-opening experience as M-System took center stage.

Brad Katz, system designer at San Francisco-based JK Sound, commented: "The M-Force is very exciting and it is nice to see such a breakthrough in driver technology. The most compelling thing I saw at the demo is the passion that the Powersoft team has brought to the table -- it is very clear to me that this company is trying push the audio industry forward, and this is where it is at for me."

The M-System is the ultimate solution for high output power subwoofers, utilizing Powersoft's patented M-Force motor transducer, its M-Drive switching mode amplifier module, and its differential pressure control (DPC) technology. M-System is the most powerful and efficient technology for subwoofers in the world, capable of reproducing 150dB SPL or more out of a single cabinet.

"M-Force represents the pinnacle of all of Powersoft's engineering developments that have transpired over the last 20 years," commented Kurt Metzler, director of sales at 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, which occurred on November 18 and 20, also included a demonstration of Powersoft's other innovative amplifier lines, including K Series, X Series, and its Armonia software, which puts powerful DSP and control capabilities to the hands of the user. The sessions highlighted the overall advantages of Class D amplification, which Powersoft introduced in 1995. These include more efficient power consumption, lower heat dissipation, and a smaller physical footprint, and among other benefits.

Attending "Xperience The Power" was a diverse group of designers, systems integrators, touring and rental operators, dealers, and loudspeaker manufacturers. "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," Metzler continued. "As Powersoft does not manufacture loudspeakers, this represents a vast opportunity for the market at large."

Building on its earlier innovations including Class D technology, power factor correction (PFC), and differential pressure control (DPC), Powersoft's M-System represents a new paradigm shift in low frequency application. The system consists of M-Force, an innovative transducer based on a patented moving magnet linear motor structure, and M-Drive -- an amplifier module specifically designed to capitalize on the potential of the M-Force technology. M-System delivers unprecedented power handling capabilities, electromagnetic conversion, reliability, and maximum SPL. M-System is reliable and built to last, able to withstand years of operation and performance.

The M-System was a core component of the largest subwoofer installation in the world, which occurred at Hollywood's Avalon Sound earlier this year. The technology was also used for this year's red carpet event at the Grammy Awards, held in Los Angeles last February. The M-System is a nominee for the 31st Annual NAMM Technical Excellence & Creativity Awards, which will be announced at the 2016 NAMM Show in Anaheim, California on January 23rd.

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

• Ability to recycle Back-EMF (electro motive force) from the loudspeaker, creating better damping efficiency and enabling power banking of energy.
• Provides higher power density and higher output than any amplifier module in the world.
• Capability of delivering high power and current at a very low impedance load.

Powersoft holds a total of five patents on M-System: two on M-Force, one on M-Drive, and two on DPC.
