Martin Audio Wavefront Precision WPS 3-Way Line Array Element
WPS sits between WPM and WPC, a passive three-way element that gets a full midrange section into a 27kg cabinet. Two 8" vented-yoke neodymium LF drivers, four compression-loaded 4" mid drivers and four 1" exit compression drivers with HT polymer diaphragms produce 133dB peak with 100 degrees horizontal and 10 degrees vertical coverage.
Because it is passive at 6 ohms, one iK42 channel can drive up to three enclosures, so the same array can be run cheaply for a corporate job or at one-box-per-channel resolution for a music show. The 5 degree trapezoidal enclosure is birch and poplar ply with a three-point rigging system, side pocket and rear grip handles, and flies up to 16 boxes for installation or 24 for touring. IP54 rated, MIL-STD-810H tested, black or white with a matching grille.
