Product Description


Martin Audio WMX

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.


  • Very high output compact Hybrid® folded horn/reflex loaded subwoofer.
  • Single 18" (460mm) ultra-long excursion high power drive unit
  • Frequency response 35Hz-150Hz ± 3dB (-10dB @ 28Hz) 104dB 1W/1m
