TOA HB-1 8-Inch 240W Flush-Mount Subwoofer
Product Overview
The TOA HB-1 is a high-power flush-mount subwoofer using an 8-inch (20 cm) cone woofer with a 110 mm ferrite magnet in TOA's Acoustic Super Woofer enclosure — a bandpass design that extends low-frequency response down to 45 Hz while maintaining a shallow 135 mm installation depth. Rated at 240W continuous program with an 8-ohm load, it mounts flush in standard wall or ceiling openings for architecturally clean low-frequency reinforcement. DEAL: On Sale.
Product Description
The HB-1's steel plate thin-wall frame and bandpass acoustical enclosure construction delivers SUB bass from 45 to 200 Hz without the deep cabinet depths typically required for effective bass reproduction. The aluminum voice coil bobbin and ferrite magnet provide efficient power handling for the 80W continuous pink noise / 240W program rating. Two +/- input connectors allow loop-through wiring. At 430 x 544 x 135 mm (430 W x 544 H x 135 D) and 11 kg, it fits standard in-ceiling rough-in openings used in commercial AV builds. It pairs with TOA full-range ceiling or wall speakers to complete a distributed audio system with dedicated bass support.

Typical Applications
The TOA HB-1 suits commercial spaces where in-ceiling bass reinforcement is needed without visible subwoofers: retail stores and hospitality venues wanting full-frequency background music from flush-installed speakers, corporate boardrooms or conference rooms with high-quality AV systems, hotel lobbies and entertainment spaces with full-range distributed audio, and educational or performing arts facilities using TOA distributed speaker systems with ceiling mains requiring low-frequency supplement.

FAQ
- What is the Acoustic Super Woofer enclosure? TOA's bandpass enclosure design uses internal acoustical filtering to extend bass response while limiting installation depth — enabling flush-mount subwoofer performance in spaces where a deep rear cavity is not available.
- What amplifier is required? The HB-1 is a passive speaker requiring an external 8-ohm-capable amplifier rated to deliver at least 80W continuous.
- What full-range speakers does it complement? The HB-1 pairs with TOA ceiling and wall speakers (e.g., F-Series, PC-Series) to add sub-bass coverage below their typical 80-100 Hz lower response limits.
- Can it be installed in a ceiling? Yes — the flush-mount design supports both ceiling and wall installation using standard commercial rough-in openings.
- Does the 135 mm depth fit standard ceilings? It fits most commercial suspended ceiling plenum spaces. Verify the available above-ceiling depth at the installation point before ordering.
