M Audio Model 10 loudspeaker

Tom Maker formerly of Edgeamps founded M Audio in 2011 to incorporate many of the ideas and philosophies that had accumulated on what I thought a modern speaker should be. By incorporating the latest composite materials, lightweight ceramics drivers and integral multichannel amplification and DSP as well as music streaming, we have come up with a plug'n'play hi-fidelity loudspeaker.

The model 10 starts life as aluminum, carbon fiber and fiberglass reinforced extruded polyethelene. We start with the upper enclosures' front and back plates that mount the midbass/woofers and tweeters. These plates are machined from .750-thick 6061 aluminum heat treated and anodized black. Next we move to the horizontal tube enclosures. The top and bottom tubes are a composite of fiberglass reinforced polyethelene aluminum and carbon fiber.

The interiors of the tubes are lined with rock wool manufactured from rocks. The middle tube is made up of 6061 aluminum housing the crossover and electrical parts. The front and back plates are held in compression by four axially wound carbon fiber tubes with adjustable tensioners on the back plate. These rods are used for adjusting each speaker's resonant frequency. The upper cabinet assembly is mounted to the subwoofer cabinet via a 6061 aluminum machined and welded bracket.

Electrical connection is made via a 4-pin gold watertight low-loss connector. The subwoofer cabinet houses the amplifiers, digital signal processor and music streaming electronics as well as a 330mm woofer. The cabinet is made of 1-inch thick high-density MDF, hand-laid carbon fiber reinforcement and an aluminum composite panel made from 2 layers of aluminum sheet bonded to a polyethylene core.
