The XP15 Blackline Powered  2-Way Loudspeaker- Featuring 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. Onboard 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 presets 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.

    Product Rating

    “By far the best service I’ve ever experienced. I was importing a product to Canada and the whole experience was quick, easy and seamless. These guys really care about running a good business. Not to mention the price was cheaper than the stores here even after importing. Definitely will do more business in the future.”
