Meyer Sound MSL-3A Loudspeaker
Designed to perform in a wide range of large-scale sound reinforcement applications, the high-power, arrayable MSL-3A allows for coherent, controlled coverage of wide areas in theater, club and concert sound reinforcement. The efficient loudspeaker delivers high sound pressure levels with extremely low distortion, for maximum intelligibility and fidelity. The biamplified loudspeaker consists of two proprietary 12-inch low-frequency cone drivers in a unique horn-loaded, vented enclosure, and a single high frequency driver with a 70-degree horn. The rugged, multiple-ply hardwood cabinet is fitted with handles. The MSL-3A requires a high-quality professional stereo power amplifier capable of delivering up to 400 watts/channel continuously into 4 ohms, with a signal voltage gain of 10 dB (minimum) to 30 dB (maximum).
