About the Meyer Sound MSL-3A
The Meyer Sound MSL-3A is a high-power, arrayable loudspeaker designed for a wide range of large-scale sound reinforcement applications, including concert touring, theater, live music clubs, and indoor or outdoor paging. The biamplified enclosure features two proprietary 12-inch low-frequency cone drivers in a horn-loaded, vented cabinet, paired with a single high-frequency driver fitted with a 70-degree horn. This configuration delivers high clarity, coherence and intelligibility with very low distortion. The rugged multiple-ply hardwood cabinet includes handles and optional aircraft-style rigging pan fittings. The MSL-3A requires a professional stereo power amplifier capable of up to 400 watts per channel continuously into 4 ohms.
Meyer Sound MSL-3A — buyer FAQs
What is the Meyer Sound MSL-3A and what is it designed for?
The Meyer Sound MSL-3A is a high-power, arrayable loudspeaker built for large-scale sound reinforcement. It is suited to main PA arrays, concert touring, theater, live music clubs, and indoor or outdoor paging and announcing. Its biamplified design combines two proprietary 12-inch low-frequency cone drivers in a horn-loaded, vented enclosure with a single high-frequency driver fitted with a 70-degree horn.
Who makes the MSL-3A and where does it fit in their range?
The MSL-3A is made by Meyer Sound Laboratories, an American professional audio company founded in 1979 and based in Berkeley, California. Meyer Sound is known for loudspeakers, line arrays, subwoofers and audio systems used across sound reinforcement, fixed installation and live performance. The MSL-3A sits within the company's high-power arrayable loudspeaker category, aimed at demanding large-venue applications.
What amplifier does the Meyer Sound MSL-3A require?
The MSL-3A is a passive, biamplified loudspeaker and requires a separate high-quality professional stereo power amplifier. That amplifier must be capable of delivering up to 400 watts per channel continuously into 4 ohms, with a signal voltage gain of between 10 dB minimum and 30 dB maximum. Buyers should confirm they have a suitable amplifier before purchasing a used unit.
How does the MSL-3A achieve low distortion across a large coverage area?
The MSL-3A uses two proprietary 12-inch low-frequency cone drivers housed in a horn-loaded, vented enclosure, paired with a single high-frequency driver on a 70-degree horn. This configuration is designed to deliver high sound pressure levels with extremely low distortion, supporting intelligibility and fidelity. The arrayable format also allows multiple units to be combined for coherent, controlled coverage of wide areas.
What should I check when buying a used second-hand MSL-3A?
Check that both 12-inch low-frequency drivers and the high-frequency driver are functioning without distortion or damage. Inspect the multiple-ply hardwood cabinet for structural integrity, and confirm whether aircraft-style rigging pan fittings are included if flying the cabinet is needed. Verify the input connectors are in good condition.
