Martin Audio Wavefront Precision WPC 3-Way Line Array Element

The WPC is the mid-size element of the Wavefront Precision family, a bi-amplified three-way box built for arrays that have to cover a wide room without losing the front rows. Two 10" long-excursion neodymium drivers sit in a Hybrid slot-horn, two horn-loaded 5" mid drivers carry the vocal range, and four 0.7" exit compression drivers handle the top, giving 100 degrees of horizontal coverage and a tight 10 degree vertical slice per cabinet.

Cabinet resolution is set by how many boxes you hang per amplifier channel pair: one to three enclosures per pair on an iKON iK42, so a rental house can trade array control against amplifier count job by job. The enclosure is multi-laminate birch and poplar ply with a 5 degree wall angle and an integral three-point rigging system that flies up to 16 boxes from one frame. It is rated IP54 and tested to MIL-STD-810H, and ships in black or white with a matching HEX-perforated steel grille.
