About the Meyer Sound MSL-6
The Meyer Sound MSL-6 is a self-powered loudspeaker built for large-scale PA and musical sound reinforcement. Its compact trapezoidal cabinet houses two 12-inch low-frequency cone drivers in horn-loaded vented enclosures, each independently amplified, plus three high-frequency horn drivers with a 2-inch throat and 4-inch diaphragm. Integrated control electronics and amplifiers eliminate the need for external amplifier racks. A 25-degree vertical coverage angle supports long-throw arrays of up to three vertical rows, while the center and outer HF horns use separate amplifier channels to achieve a 30-degree horizontal coverage angle per unit. Tight-packing two units yields 60 degrees, and the modular design scales up to twelve units for full 360-degree circular coverage. Twelve pivoting lift rings, each rated to 1,500 lb working load at a 5:1 safety factor, are included for rigging.
Meyer Sound MSL-6 — buyer FAQs
What is the Meyer Sound MSL-6 and what is it designed for?
The Meyer Sound MSL-6 is a self-powered loudspeaker built for large-scale vocal public address and musical sound reinforcement. Its compact trapezoidal cabinet integrates amplifiers and control electronics for two 12-inch low-frequency cone drivers and three high-frequency horn drivers, eliminating the need for external amplifier racks. The design is intended for long-throw applications where consistent, controlled coverage across a large audience area is required.
How does the MSL-6 array system work and how large can it scale?
Each MSL-6 unit provides a 30-degree horizontal coverage angle, achieved through separate amplifier and control electronics for the center and outer high-frequency horns. Tight-packing two units yields 60 degrees, and the modular design allows each additional unit to add another 30 degrees. A maximum array of twelve units produces full 360-degree circular coverage. Vertically, the 25-degree coverage angle supports up to three rows with minimal overlap between them.
What rigging provisions does the MSL-6 include?
The MSL-6 has twelve pivoting lift rings, six on the top and six on the bottom of the cabinet. Each ring has a maximum working load capacity of 1,500 lb at a 5:1 safety factor. This rigging provision is built into the cabinet despite the unit already housing integrated amplifiers and control electronics, reflecting its intended use in flown large-scale arrays.
Who makes the MSL-6 and where does it fit in their product range?
The MSL-6 is made by Meyer Sound Laboratories, an American professional audio company founded in 1979 by John and Helen Meyer and based in Berkeley, California. Meyer Sound is known for self-powered loudspeakers used in sound reinforcement and fixed installation, and the MSL-6 represents that self-powered approach applied specifically to high-output, long-throw large-venue PA work.
What should I check when buying a used Meyer Sound MSL-6?
On a used MSL-6, confirm that the integrated amplifiers and control electronics are fully functional across all driver channels, since the center and outer high-frequency horns run on separate amplifier paths. Check the condition of all twelve pivoting lift rings if the unit is intended for flying. Verify the cabinet and horn integrity. Each listing on this page includes condition details, and purchases through 10K Used carry a 21-day warranty covering major functional faults; the buying guide at 10kused.com/used-av-equipment-guide/ covers the full process.
