SXF115

Compact, Direct Radiating Subwoofer

SXF115 | Compact Passive Subwooferr
Where to Buy or Rent

The SXF115 is a passive subwoofer designed to extend the performance of Martin Audio WPM and MLA Mini systems down to 42Hz. Featuring a powerful, long-excursion 15” (380mm)/4” (100mm) voice coil driver in a very compact bass reflex enclosure, it can be flown as part of a WPM or MLA Mini array, or ground-stacked separately.

Features

  • Compact, high-performance subwoofer
  • Ultra-long excursion 15” (380mm) driver with 4” (100mm) voice coil
  • Large ports for reduced air noise
  • Integral flying hardware compatible with WPM and MLA Mini
  • M20 threaded pole-mount fitting
  • Bar handles and skids

Applications

  • Touring sound reinforcement for small and medium-size venues
  • Fixed installations in concert halls, theatres, ballrooms and HoW
  • Sports stadium and arena installations
  • Corporate AV events and conferences

The design of the 15” driver maximises output while minimising power compression and distortion, and four reflex ports reduce air noise at very high output levels. The SXF115 enclosure is constructed from multi-laminate birch ply, finished with a durable polyurethane coating and equipped with a perforated steel grille, skids and twin bar handles. An M20 threaded fitting in the top surface facilitates pole-mounting of up to 4 WPM or MLA Mini enclosures.

Being a passive subwoofer, the SXF115 is ideal for flown WPM or MLA Mini fixed installations where ground-based, rack-mount amplification is preferred — either for ease of servicing, increased IP protection, or reduced visible cabling in the air.

When used with a WPM or MLA Mini array, Martin Audio iKON amplifiers or the MSX rack-mount power plant respectively deliver the correct drive characteristics to the SXF115, with onboard DSP presets for a variety of system configurations. Cardioid operation can be achieved by arranging the SXF115 in forward and rear-facing pairs.
