TOA Electronics 8" Indoor Subwoofer System
The TOA FB-08BT is an indoor subwoofer system engineered for commercial public address and background music installations. Featuring a high-performance 20 cm (8") bass-reflex enclosure, it delivers powerful low-frequency reinforcement from 45 to 300 Hz, filling spaces with clean, natural bass that complements foreground and background audio equally. The FB-08BT's built-in crossover network eliminates the need for external processors, making it straightforward to integrate with TOA's F-03 and F-05 satellite speakers for a complete, full-range distributed audio system.
The subwoofer supports both low-impedance direct wiring and high-impedance 70 V / 100 V constant-voltage line connections, with multiple power tap selections to optimize coverage across different space sizes. Optional wall and ceiling mounting brackets are available for versatile positioning.
Key Features
| Feature | Benefit |
|---|---|
| 8-inch bass-reflex enclosure | Delivers low-frequency extension from 45 Hz with natural, controlled bass |
| Built-in crossover network | Eliminates external processor requirements when paired with F-03/05 satellite speakers |
| 120 W rated / 240 W program power | Handles demanding continuous playback in commercial installations |
| 70 V / 100 V line compatibility | Integrates directly into distributed constant-voltage PA systems |
| Multiple power tap settings | Allows output level matching — 30 W, 60 W, or 100/120 W — to coverage area size |
| M4 screw terminal input | Provides secure, tool-free field wiring connections |
| Optional mounting brackets | Wall (HY-WM-FB08B) or ceiling (HY-CM-FB08B) mounting for flexible installation |
Typical Applications
The FB-08BT is suited for commercial venues where distributed audio systems require extended bass response. Typical deployments include retail stores, restaurants, hotel lobbies, conference halls, fitness facilities, entertainment venues, and sports facilities where the F-03 or F-05 satellite speakers form the main distributed system. It is also well-suited for houses of worship requiring low-frequency reinforcement without a large standalone subwoofer.
