What is the Martin Audio WPL?
The Martin Audio WPL is a professional passive line array loudspeaker designed for high-quality sound reinforcement in medium to large venues.

An amplifier delivering 500-1000 W continuous per channel at 8 Ω is recommended to achieve full performance without clipping.
Can the WPL be used without a subwoofer?
