MARTIN AUDIO F15-PLUS

The 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" (380mm) LF driver and a new 1.4" (35mm) exit compression driver mounted on a rotatable 80° x 50° 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 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 new 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.
