Meyer Sound MSL-2A Loudspeaker

Meyer Sound MSL-2A Loudspeaker

The Meyer Sound MSL-2A is a high-powered, wide coverage loudspeaker for professional sound reinforcement applications. Specifically designed for touring reinforcement, the accurate, rugged MSL-2A is a bi-amplified system consisting of a proprietary 15-inch low-frequency driver in a vented enclosure, and a 70-degree high-frequency horn with a 2-inch (throat diameter) driver. The MSL-2A’s drivers provide exceptional efficiency and power handling, with low distortion for maximum clarity. The sturdy, multi-ply hardwood enclosure with textured finish is designed to withstand road abuse. The MSL-2A comes with handles and, optionally, aircraft-style rigging pan fittings or nut plates. The MSL-2A requires a high-quality professional stereo power amplifier capable of delivering up to 600 watts per channel continuously into 8 ohms, with a signal voltage gain of 10 dB (minimum) to 32dB (maximum).
