Martin Audio SXF115
Direct Radiating
Compact 15" Subwoofer
Description
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, 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.
By adding the input board cover accessory, the subwoofer is fully weather resistant and suitable for permanent outdoor usage.
