HK Audio FINEO-FO-S112-WHT 12" Passive Installation Subwoofer (White)

Signal White Compact 12 Inch Install Subwoofer for Tight Spaces

The HK Audio FINEO FO S112 WHT is a passive 12-inch installation subwoofer designed to add powerful low-end support in rooms where space is limited and aesthetics matter. It’s an ideal system subwoofer for compact speakers like the FO 5, and it also works well as a surround LFE subwoofer in immersive audio installations that need clean bass without oversized enclosures.

Punchy Bass Support Tuned for Musical Low Frequencies

A 12-inch woofer with a 2.5-inch voice coil and a 50 Hz tuning frequency delivers tight, musical bass with strong output for its size. With 600 W RMS handling at 8 ohms, the FO S112 provides practical headroom for foreground music and event playback while maintaining controlled response through the low-frequency range.

Close To Wall Placement with Smart Rear Cable Routing Cutouts

The cabinet is designed to install cleanly against a wall. A rear cable feed-through with cut-outs on the left, right, or bottom allows wiring to run close to the wall surface, so the subwoofer can be placed flush without leaving awkward gaps. This is especially helpful for hospitality, retail, and corporate installs where neat cable management is a priority.

Protected Bass Reflex Port for Public Facing Environments

A secondary grille protects the bass reflex port from accidental contact and unwanted object insertion. This extra layer of protection is valuable in schools, gyms, and public spaces where equipment may be within reach and needs to stay reliable without constant supervision.

Ball Impact Certified for Sports Facilities and Multipurpose Rooms

The FO S112 includes a ball-impact resistance certificate in line with DIN 18032-3, supporting use in athletic environments and sports halls. This certification helps meet facility requirements while keeping the system compact and install-friendly.

Straightforward Integration with Amplifiers and DSP Processing

Because this is a passive subwoofer with no internal crossover, it’s easy to integrate into common amplifier and DSP workflows. NL4 Speakon input and parallel output support clean linking, and published EQ filter guidance is available for many common processing platforms to help you tune the subwoofer to your loudspeakers and room.
