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.
WPL is a full-scale line array which is capable of exceptionally high output for its modest size and weight.
A three-way, bi-amped system, its very high output is achieved by utilising Martin Audio’s trademark horn-loading technology across all frequency bands — increasing the acoustic output of the low frequency section, as well as the midrange and HF.
It incorporates 2 x 12” (300mm) drivers with Hybrid® horn/reflex loading, 2 x 6.5” (165mm) cone drivers on a midrange horn which covers the vocal frequency range from 300Hz to 4kHz, and 3 x 1” (25mm) exit HF drivers operating from 4kHz upwards. Each section features innovative horn-loading techniques and refinements which raise the acoustic performance of WPL to a superior level — both in terms of output and smooth 90° horizontal coverage patterns of the mid and HF horns. Sonically, WPL’s exemplary horizontal dispersion pattern translates to an incredibly consistent frequency response off-axis, with minimal variation from the on-axis response.
The maximum peak outputs of the LF, Mid and HF sections are 139dB, 140dB and 145dB per enclosure @ 1m and 6dB crest factor, respectively — ensuring that a WPL array will meet the most demanding requirements for throw and clarity in the largest venues and outdoor events.
