Martin Audio WMX Hybrid™

Line Array Systems

?Martin Audio line array systems combine innovative horn-loading techniques with line array technology to produce extremely powerful systems with maximum dynamic impact.

Utilising proven and patentable driver-loading techniques, together with no-compromise vertically-coupled waveguides and true constant directivity horns, the Martin Audio line arrays achieve levels of efficiency and coverage consistency not usually found in this popular format.

More than ever, attention is focussed on how easy a system is to fly. The proprietary rigging systems of the Martin Audio line arrays are safe, quick to assemble and allow for a wide range of column curvatures to be achieved.

By hinging at the front rather than the rear, the rigging system minimises gaps between the acoustic elements which would otherwise interfere with the continuous column effect. All the flying hardware required is integral and captive.

The result of Martin Audio’s no compromise design, of all horn-loaded line arrays, is that music’s subtle nuances are reproduced with exceptional accuracy and unrivalled sonic performance.

Martin Audio line arrays – in a class of their own.

Martin Audio WMX Hybrid™

* 18” flown/ground Hybrid™ sub for W8LM/W8VDQ

* Hybrid® horn and reflex loaded subwoofer

The Martin Audio WMX is a compact, high performance flown or ground stacked subwoofer featuring our trademark Hybrid® loading. Primarily intended for use with the W8LM/W8LMD, it shares the same cabinet width and is directly compatible with the W8LM and its flying hardware.

A single long-excursion 18" (460mm)/ 4" (100mm) coil driver is front loaded by a hyperbolic horn with an ultra-low flare rate. The rear of the driver is reflex loaded to extend the LF output to below the natural cut-off point of the horn. This Hybrid® technique marries the very high efficiency of horn loading with the extended low frequency response of a reflex enclosure.
