Martin Audio Blackline F8 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 8" miniature PA/monitor system


Ultra-compact two-way passive system

The Blackline F8+ is a versatile, two-way passive system designed for applications where high output is required from an ultra-compact enclosure. It features a long-excursion, 8” (200mm) low frequency driver and a 1” (25mm) HF compression driver mounted on a constant directivity 90° x 50° horn. The horn is user rotatable to allow the F8+’s multi-angle enclosure to be used in either its vertical or horizontal orientation, depending on the application.

Use of a controller with the F8+ is optional. For demanding applications, an M3+ or DX1.5 controller configured to perform EQ and limiter functions is recommended.
