The MSL-2A is a high-powered, wide-
coverage loudspeaker for professional
sound reinforcement applications. Specifi-
cally designed for touring reinforcement,
the accurate, rugged MSL-2A is a biampli-
fied system consisting of a proprietary 15-
inch low-frequency driver in a vented en-
closure, and a 70-degree high-frequency
horn with 2-inch (throat diameter) driver.
The MSL-2A’s drivers provide excep-
tional efficiency and power handling, with
low distortion for maximum clarity.
The sturdy, multi-ply hardwood enclo-
sure 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 32␣dB
(maximum).
