Description
The HK AUDIO FINEO-FO-15-BLK-U is a powerful passive 2-way installation speaker designed for professional sound reinforcement in larger rooms and venues. Its 15" Sica woofer with a 2.5" voice coil works with a 1" Sica compression driver to deliver clear speech, expressive midrange, and a strong bass foundation. With 500W RMS, 1000W program, and 2000W peak power handling, it is the most powerful model in the FINEO speaker family.
A BEM-optimized constant-directivity horn provides 80° × 60° sound dispersion and can be rotated by 90° to suit different mounting orientations. The speaker offers 95 dB sensitivity, up to 126 dB peak SPL, and a frequency range extending from 61 Hz to 20 kHz at -10 dB. Its bass-reflex enclosure and integrated crossover support consistent sound reproduction for speech and music applications.
Built for demanding professional installations, the FO-15 features an MDF cabinet with an acrylic enamel finish, a corrosion-protected steel grille, acoustic foam backing, and additional steel reinforcements. Multiple M8 mounting points support flexible installation, while NL4 Speakon input and parallel output connections simplify system integration. It can also be combined with HK AUDIO S118 or S218 subwoofers for extended low-frequency performance.
