The TOA FB-120 is a compact indoor subwoofer designed for professional AV integrators and production teams who need reliable low-frequency reinforcement in permanent or temporary installations. Built around a high-power 30 cm woofer, it is engineered to complement TOA's HX-5 series full-range speakers, extending the system's bass response for applications in conference centers, houses of worship, retail environments, and live event productions. Where many compact subwoofers force a trade-off between mounting flexibility and acoustic output, the FB-120 supports rigging, floor, wall, corner, and ceiling mounting. This makes it a practical choice for integrators who need to adapt a single product across different room types and installation constraints. Multiple units can be cascaded to scale coverage as the job demands, without introducing additional signal path complexity. The FB-120 connects via Speakon NL4MP and M4 screw terminals, fitting cleanly into standard passive loudspeaker signal chains. Its plywood enclosure and steel grille construction reflect a build quality appropriate for semi-permanent and permanent installs, and the integrated carry handle supports efficient deployment in temporary production setups. Available in black and white finishes to match room aesthetics or existing system components.
