Martin Audio Wavefront Precision WPM 2-Way Line Array Element
WPM is the small end of the Wavefront Precision range and the one that fits where a full array will not. At 14kg and 500mm wide it carries two 6.5" contoured-diaphragm neodymium LF drivers and three 1.4" aluminium dome compression drivers on a constant-directivity waveguide, covering 100 degrees horizontally and 10 degrees vertically per box.
It is a passive 16 ohm cabinet, so up to four enclosures can run from a single iKON amplifier channel on an iK41, iK42 or iK81, and array resolution can still be dialled up by giving each box its own channel. Construction matches the larger Wavefront boxes: multi-laminate birch and poplar ply with a 5 degree wall angle, an integral three-point rigging system, side pocket and rear grip handles, IP54 rating and MIL-STD-810H testing. Black or white paint with a matching HEX-perforated steel grille.
