The Martin Audio Blackline F15+ is a high-power, wide-bandwidth two-way passive loudspeaker in a compact and efficient package. A 15-inch (380mm) neodymium LF driver with a 3-inch (75mm) voice coil teams up with a 1.4-inch (35mm) exit compression driver mounted on a user-rotatable 80 x 50 degree constant directivity horn, delivering extended response from 55Hz to 18kHz. With 400W AES power handling, 100dB sensitivity and up to 130dB peak SPL, the F15+ handles demanding applications where ease of installation or fast deployment matters. Its ergonomic multi-angle birch ply cabinet works equally well front-of-house or as a high-power floor monitor, while the rotatable horn simplifies near-ceiling aiming in venues with restricted height. Twelve M8 threaded inserts allow horizontal or vertical mounting, and the top hat fitting accepts speaker stands or a distance pole over a subwoofer such as the Blackline S18+. Ideal for live club performance, high-powered stage monitoring and installed sound, the F15+ gives Kenyan churches, bands and rental companies a dependable single-box solution with professional headroom.
