The Blackline F12+ is a high power, compact two-way system with a new, vented-chassis, 12 inch (300mm) LF driver and a new 1 inch (25mm) exit compression driver mounted on a rotatable 80˚ x 50˚ constant directivity HF horn. The LF driver has a tough, water resistant cone and features a high BL motor with a flat-wire copper coil and an aluminium demodulating ring. This reduces intermodulation distortion and improves midrange performance when driven hard. Increased excursion is available by virtue of a triple roll surround and deep motor structure. The directivity of the LF driver has been matched to the HF horn in the crossover region by improved crossover design and cone profile optimisation, also the new HF compression driver utilises an ultra-lightweight Kapton diaphragm for extended high frequency response.

The F12+ is the ideal choice for fullrange applications calling for an efficient, reliable workhorse that is equally suitable for fixed installations or quick deployment mobile operations. Its ergonomic design and rotatable HF horn makes near-ceiling mounting and aiming easy in venues with restricted height, whilst its multi-angle birch ply cabinet also allows it to be used as a highly intelligible floor monitor. Ten M8 inserts and four M8 bracket inserts make a variety of mounting methods possible including horizontal or vertical mounting.

The F12+ comes with a top hat fitting for speaker stand mounting. This fitting can also be used as a pole socket when the F12+ is used with a Blackline S15+ or S18+ subwoofer.
A Martin Audio M3+ or DX1.5 Electronic Controller is available to provide F12+/subwoofer crossover and limiter facilities.
