It features two 5-inch full-range transducers housed in a cylindrical flameproof ABS enclosure, delivering consistent sound projection in both directions.
Flexible 100V Power Selection
The integrated constant-voltage transformer provides four selectable 100V power settings of 12W, 6W, 3W, and 1.5W, allowing the speaker to be matched to different distributed audio system requirements. Ceramic screw terminals provide reliable input and output connections, while thermal fuse protection helps safeguard the speaker during operation.
Durable Indoor & Outdoor Installation
The BD-42EN-12W combines an ABS body with aluminum grilles and an aluminum U-bracket for durable professional installation. Its IP55 protection rating makes it suitable for both indoor and outdoor environments, while the adjustable bracket design allows convenient orientation for effective sound coverage. CE compliance and EN54-24 certification make it suitable for professional voice alarm and commercial sound applications.
