3-Way Bi-Amp
2 x 12” Line Array Element
The scalable resolution of WPL [Wavefront Precision Longbow] offers greatly improved coverage consistency and control compared to a standard line array and provides a flexible pathway to advanced array control.


With the launch of the Wavefront Precision™ Series (WPM and WPC) the concept of scalable resolution was born — harnessing the research and technology behind Martin Audio’s self-powered MLA® Series systems in a new line array format with external amplification.
Delivering unmatched sound quality, coverage consistency and control in an affordable package, this uniquely flexible and upgradeable approach has been rapidly adopted by sound rental and installation companies worldwide to become the company’s fastest ever selling line array series.
Wavefront Precision Longbow (WPL) now brings this high performance, control and flexibility to large-scale touring and install applications. Designed as a complete system with external iKON® multi-channel amplifiers, automated DISPLAY™ optimisation software and VU-NET™ control platform, WPL provides financial accessibility to the top echelons of touring and install sound — from prestigious stadium concert and outdoor festivals, to high-specification arena and House of Worship installations.
The complete system philosophy guarantees that WPL arrays perform predictably and effortlessly to their design maximum, as well as ensuring that they are compatible with other WPL systems throughout the world.
