Martin Audio Blackline F15+ Two-Way Passive System with 15" Low Frequency & 1.4" Exit Compression Driver, 55Hz-8kHz, 100dB Sensitivity, 8 Ohms Impedance, 1600W Peak

The Martin Audio high power Blackline F15+ is a high performance, wide-bandwidth system in a compact and efficient package. Extended frequency response is provided by a new 15" / 381mm LF driver and a new 1.4" / 35.56mm exit compression driver mounted on a rotatable 80deg. X 50deg. constant directivity HF horn. The new 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 aluminum 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 new HF driver utilizes 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 optimized to match the directivity of the HF horn and LF section through the crossover region.

It 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. It comes with a top hat fitting for speaker stand mounting. This fitting can also be used as a pole socket when it is used with, for instance, a Blackline S18+ subwoofer. A Martin Audio M3+ or DX1.5 Electronic Controller is available to provide F15+/subwoofer crossover and limiter facilities.
