Martin Audio WLX

The Martin Audio WLX is a high performance subwoofer featuring our trademark horn loading expertise. A derivative of the WSX, the WLX is smaller, lighter, can be flown or ground stacked with W8 line array systems and possesses high output capability with low frequency extension. A single ultra-long excursion 18" (460mm)/ 4" (100mm) coil driver is front loaded by a hyperbolic horn with 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.
