Description
The HK AUDIO FINEO FO-S112 is a compact passive installation subwoofer designed to deliver powerful low-frequency reinforcement in professional sound systems. Its 12-inch Sica woofer, 2.5-inch voice coil, and bass-reflex cabinet provide strong bass output with 600W RMS, 1200W program, and 2400W peak power handling.
With a frequency response extending down to 42 Hz at -10 dB, the FO-S112 provides low-end support for compact FINEO loudspeakers, including the FO-5. It is suitable for use as a system subwoofer or for low-frequency effects (LFE) in surround installations where space is limited.
Designed for practical fixed installations, the cabinet features rear cable-routing cutouts that allow connections to exit left, right, or downward for close-to-wall placement. Its reinforced steel grille and secondary bass-reflex port protection help protect the speaker in demanding environments, while DIN 18032-3 ball-impact certification makes it suitable for installations in sports facilities.
