Ideal partner for flown WPS arrays

Martin Audio SXCF118 (MAU-SXCF118B) Compact Cardioid Flown Subwoofer complements flown WPS arrays with incredibly powerful low frequency output and unique pattern control. Independently driven front and rear facing drivers maximize front radiation in a cardiod dispersion pattern and increase rear rejection to elicit an additive response with improved accuracy and impact. The rugged design of these subs feature four grab handles, steel grilles, and interlocking skids to reduce movement when stacked. Additional design versatility is given through the threaded pole-mount plate and integrated flying hardware (eyebolts and flying frame sold separately). With the weather kit accessory, the SXCF118 can be made weather resistant and suitable for outdoor applications.


  • Front facing 18” (460㎜)/4” (100㎜) voice coil driver
  • Rear facing 14” (356㎜)/3.5” (88㎜) voice coil driver
  • 28㏈ rear rejection at 75㎐
  • Tour-grade plywood enclosure with hard-wearing polyurea coated finish
  • Four grab handles and foam-backed perforated steel grilles
