Martin Audio Blackline F15 Plus

Blackline+ systems are synonymous with exceptional sound quality and reliability and have become the benchmark for premium live music venues, nightclubs and installations worldwide.


All low frequency drivers used in the two-way systems now benefit from the addition of aluminium demodulation rings to minimise the variation in voice coil inductance as the coil moves in the gap. The result is improved midrange clarity and reduced intermodulation distortion at high excursions, ensuring that the sound balance and quality is maintained even at high levels.


In the development of the Blackline+ Series, special attention has also been given to matching the directivity of the low frequency drivers to the HF horns in the crossover region. This has been achieved by careful choice of LF cone profiles, together with improvements in the crossover design.


Blackline+ – superior by design.

 

2way passive 15" system high power PA/monitor system


Wide-bandwidth system


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.


A Martin Audio M3+ or DX1.5 Electronic Controller is available to provide F15+/subwoofer crossover and limiter facilities.
