The Blackline F12+ is a high power, compact two-way system with a new, vented-chassis, 12” (300mm) LF driver and a new 1” (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.
