MSL10 (1980)
Meyer Sound
The MSL-10 improved on the design John Meyer had employed to build the JM10 for McCune Sound. The JM10 had been the first large-scale arrayable loudspeaker and had seen use by the Grateful Dead and others. The MSL-10 actually was created for an installation at the Oakland Coliseum, where high-quality sound was desired so that the audience and players could both clearly hear the system.
The MSL-10 was a high-power, high-Q system, powered by its own MS-10 amplifiers and M-10A controller, that provided 30-degree sections that could be combined into arrays to cover areas as wide as needed. One of the design goals was to prove the validity of the architecture, then create a product that broke the MSL-10 into smaller "chunks" that could be arrayed more flexibly. That product turned out to be the MSL-3.
