Martin Audio Blackline S18 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.

 

Direct radiating 18" high power sub


The compact Blackline S18+ sub-bass system has been designed to be used with Blackline F12+ and F15+ full-range systems to extend and increase the total low frequency output power. The S18+ provides good bass punch with extended sub-bass output from a new, long-excursion, 18” (460mm)/4” (100mm) voice coil driver with a water resistant cone and triple roll surround.


The S18+ is provided with a top hat fitting that can be used to pole mount an F12 or F15 above the enclosure.
