Featuring a powerful, long excursion 15” (380mm)/4” (100mm) voice coil driver with a water-resistant cone and triple roll surround, it delivers dynamic low frequency performance from a very compact enclosure.

The durable plywood enclosure is finished in hardwearing textured paint and incorporates threaded inserts for eyebolt suspension of a single enclosure, as well as safety points. Inserts are also provided for the attachment of side rigging strips to assemble a flown installed array of up to four enclosures.

Ergonomic pocket handles assist handling and installation, and the driver is protected by a coated steel grille with an acoustically transparent fabric backing. An M20 threaded plate on the top surface facilitates pole-mounting of Martin Audio full-range enclosures.

The SX115 can be used as a stand-alone subwoofer or stacked using locating skids and mating channels at the base and top of each enclosure. Cardioid operation can be achieved by arranging the SX115 in forward and rear-facing pairs, with each enclosure powered individually in conjunction with dedicated DSP presets.

The SX115 is available in black and as standard is suppled without castors which are available as an accessory pack.
