The TOA FB-08BT is a premium compact indoor subwoofer system designed to deliver powerful low-frequency reproduction for a wide range of commercial audio applications. Featuring a high-performance 20 cm (8") cone driver housed in a bass-reflex enclosure, this subwoofer provides deep, articulate bass that enhances the overall audio experience in retail spaces, restaurants, educational facilities, and corporate environments. The FB-08BT is specifically engineered to integrate seamlessly with TOA's F-03BT and F-05BT surface-mount speakers, creating a complete audio solution that delivers full-range sound without requiring external processors or complex system configurations. Available in black (FB-08BT) with a sleek, unobtrusive design that complements modern architectural aesthetics, with a white variant (FB-08WT) also available for installations requiring color matching with lighter décor schemes.

What sets the FB-08BT apart is its built-in crossover network, which simplifies system configuration and eliminates the need for additional signal processors when paired with F-03BT or F-05BT speakers. This intelligent design allows for straightforward installation and seamless audio integration, enabling dynamic bass reproduction that enhances music playback and adds impact to announcements. The MDF enclosure is precisely tuned to optimize low-frequency response, delivering a frequency range of 45 Hz to 300 Hz that adds substantial depth and richness to the overall sound system. With a sensitivity of 90 dB (1 W, 1 m) when installed in a half-free sound field, the FB-08BT provides efficient bass performance that maintains clarity even at higher volume levels. The rugged construction features a durable MDF enclosure finished in black (RAL 9011 equivalent) with a surface-treated steel grille, ensuring both aesthetic appeal and long-term reliability in commercial environments.

Installation flexibility is a key feature of the FB-08BT, which supports both high impedance (100V/70V line) and low impedance (8Ω) connections to accommodate virtually any system configuration. The subwoofer offers multiple tap settings including 83Ω (120W) and 167Ω (60W) for 100V line systems, and 50Ω (100W), 83Ω (60W), and 167Ω (30W) for 70V line systems, allowing precise power matching to the amplifier and space requirements. For enhanced mounting versatility, the FB-08BT can be installed on walls using the optional HY-WM-FB08B bracket or on ceilings using the HY-CM-FB08B bracket, with both accessories designed specifically for secure and straightforward installation. With substantial power handling capabilities of 120W rated noise power and 240W continuous program power (8Ω), the FB-08BT delivers impressive bass performance while maintaining reliability in demanding commercial applications. The subwoofer's compact dimensions of 7.87" × 13.78" × 15.75" (200 mm × 350 mm × 400 mm) allow for discreet installation in space-constrained environments, making it an ideal choice for enhancing audio quality without dominating the visual space.
