Martin Audio W8LMD 3-Way bi-amp

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 W8LMD 3way bi-amp

* 2x8" downfill for W8LM

* Three-way mini, vertically arrayable enclosure


The Martin Audio W8LMD is a mini, wide-dispersion vertically arrayable enclosure. It can be used individually and in small quantities for short to medium throw applications (up to 30 metres) as well as a downfill element for the W8LM. Its 20° vertical dispersion requires fewer cabinets to cover the same area as a conventional line array element, yet it still benefits from the smooth, predictable coverage of a vertically coupled system.


* Stand alone vertically arrayable enclosure

* Line array downfill element

* Consistent 120º (-6dB) horizontal mid and HF pattern control

* 20º (-6dB) vertical dispersion

* Tripod mountable singularly or in pairs

* Amplitude shading switch

* Passive or Bi-Amp format

* Compatible with WMX, WLX, WSXa, WS2A & WS218 subwoofers


* Short to medium throw arrays of 1 to 4 cabinets

* Vertically arrayed downfill for W8LM systems

* Theatre sound reinforcement

* Corporate events

* Fixed installations
