The LF driver features a tough, water resistant cone and a lightweight, high BL, neodymium motor system with inside/outside coil windings for improved heat transfer. An aluminium demodulating ring reduces distortion and improves midrange clarity at high levels and increased excursion is available via a triple roll surround and deep motor structure. The HF driver utilises a titanium diaphragm with controlled break-up modes for improved sonic performance at high frequencies and the crossover design and LF cone profile have been optimised to match the directivity of the HF horn and LF section through the crossover region.

Blackline XH15 is perfect for higher power applications where ease of installation, or speed of deployment, are important factors. Its ergonomic design and rotatable HF horn makes near-ceiling mounting and aiming easy in venues with restricted height, whilst its multi-angle birch ply cabinet allows it also to be used as a high power floor monitor. Its twelve M8 inserts make a variety of horizontal or vertical mounting methods possible.

Blackline XH15 features integral; ergonomic handles for easier handling and comes with a discrete 35mm pole-mount socket for speaker stand mounting. This fitting can also be used as a pole socket when the Blackline XH15 is used with, for instance, a Blackline X118 or X218 subwoofer.

A full-range passive two-way system, the XH15 may be used without a controller. However, the EQ and limiter functions of a controller such as the Martin Audio DX0.5 will maximise its capabilities. When used in conjunction with a Blackline X118 or X218 subwoofer, crossover and EQ functions can be performed by the DX0.5.
