The XP15 is a self-powered two-way system designed by leading acoustic engineers for indoor portable applications and installations that require powerful performance from a single portable loudspeaker.

It features a 15” (380mm)/3” (75mm)voice coil LF drive unit, and a 1” (25mm) exit HF compression driver with a 1.75” (44mm) polyimide diaphragm. With an accurately-defined 80° x 50° coverage pattern, it combines very high output capability with exceptional sonic performance and low frequency impact.

Its Class D amplifier module delivers 1000W LF + 300W HF peak output to the drivers, which are independently protected by RMS and peak limiters. On-board DSP functions are controlled by a rotary encoder interface and multi-function, easy-to-use colour display on the rear panel. DSP features include crossover function, a three-channel mixer with three band EQ on each input channel and a choice of three voicing resets and operating modes for flexible operation without external processing.

The symmetrical, multi-angle enclosure is manufactured from birch and poplar plywood and finished in textured black paint. It is fitted with M8 inserts for eyebolt suspension plus a pole-mount socket with a removable cap. Its cloth-backed protective steel grille is a spring-fit into the sides of the enclosure for easy access to rotate the HF horn.
