Martin Audio Blackline F10 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 10" system ultra-compact PA/monitor system


Compact two-way passive system


The Blackline F10+ is a versatile, two-way passive system, designed to provide exceptional sound reinforcement and stage monitoring from a very compact enclosure. It features a powerful 10” (250mm) low frequency driver and a 1” (25mm) HF compression driver mounted on a constant directivity 90° x 50° horn. Depending on the application, the HF horn can be rotated to allow the multi-angle enclosure to be used in either its vertical or horizontal orientation. A demodulating ring fitted to the LF driver reduces distortion and improves the performance at the upper end of the LF driver’s range at high levels. Additionally, the directivity of the LF driver has been matched to the HF horn by a combination of optimisation of the water-resistant LF cone profile and improved crossover design.

Use of a controller with the F10+ is optional. For demanding applications, an M3+ or DX1.5 controller configured to perform EQ and limiter functions is recommended.
