Martin Audio WS18X, Direct radiating Ground Sub

Differential Dispersion Systems


Martin Audio’s Differential Dispersion™ systems deliver more consistent frequency response and SPL’s over the audience than from systems with fixed X° x Y° dispersion.


DD12 - Combining onboard networking, DSP and Class D amplification with state-of-the-art transducers, the compact DD12 sets a new benchmark for professional, powered two-way loudspeaker systems in terms of fidelity, output capability and coverage consistency. Its compact, multi-angle enclosure facilitates vertical or horizontal orientation, as well as use as a stage monitor.


DD6 - The ultra-compact DD6 is a passive two-way, multi-purpose loudspeaker system designed for premium applications which require ‘on-the-fly’ flexibility. Its high frequency horn can be easily rotated for horizontal or vertical use in a quick, tool free operation. Up to three DD6’s can be driven by the PSX self-powered companion subwoofer.


W8VDQ - Combines line array and differential dispersion technologies within a single enclosure — a unique solution to the requirement of even coverage over wide angles and medium throw distances from a single element. The W8VDQ has wide short-throw horizontal dispersion of 120°, reducing to 100° as the throw increases.



WS18X, Direct radiating

* 18" ground sub

* 1000 watt vented sub-bass system


The WS18X is a high performance sub-bass system designed for use with small to medium Wavefront systems, in both touring and install applications. It features a 1000 watt 18" (460mm) drive unit with magnet structure and suspension engineered for maximum linear excursion. The birch ply cabinet is fitted with four pocket handles and four 4" (100mm) castors for easy deployment. It features large area porting to reduce air noise. A top hat fitting allows mid-top cabinets to be mounted on the WS18X using the HAM09015 adjustable pole. WS18X subwoofers are designed to be powered by Martin Audio MA12K or MA9.6K amplifiers.
