BPL-56 ABS

BPL-56 ABS Back Box

Designed to provide essential structural shielding and acoustic consistency, the BPL-56 is a premium ABS protection dome back box engineered for commercial ceiling speaker installations. Serving as a premier architectural accessory, this enclosure is specifically designed to perfectly fit the PowerX CS616 ceiling speaker, making it an ideal choice for corporate boardrooms, retail environments, and transit hubs. It acts as a critical barrier, safeguarding sensitive transducers from dust, debris, and physical damage within exposed ceiling voids.

By fully enclosing the rear of the speaker, the back box provides a strictly controlled internal acoustic volume that significantly deadens unwanted structural resonance. This optimized air cavity prevents sound energy from bleeding into adjacent floors or rooms, ensuring that the acoustic output is forced downward into the intended listening space. By isolating the driver, it maximizes the overall loudness and punch of the housed transducer, ensuring optimal performance in high-ambient noise environments.

The structural engineering of this enclosure is highly precise, featuring dimensions of 147 x 87 mm (5.8 x 3.4 in) to accommodate professional ceiling speaker infrastructure without occupying excessive overhead space. It is intelligently crafted to integrate smoothly with standard mounting hardware, offering strategic routing options for electrical conduits and speaker wire. This robust architectural framework ensures the speaker is securely anchored while maintaining strict alignment and phase-accurate projection across broad listening zones.

When deployed in large-scale distributed audio networks, this enclosure ensures that the sonic character of every speaker remains absolutely identical, whether projecting highly intelligible voice paging or rich background music. It completely protects the critical transformer and low-impedance bypass wiring from environmental degradation, ensuring uninterrupted electrical performance. This uniform acoustic loading guarantees that the entire commercial audio system performs with uncompromised fidelity and clarity.

Constructed from durable, high-impact white ABS material, the unit weighs a highly manageable 360 g (0.8 lb) to prevent unnecessary strain on ceiling tiles and support rails. The rugged build quality ensures long-lasting defense against the rigors of commercial facility operations, offering a clean, hidden integration above the ceiling line. With streamlined mounting mechanisms designed for rapid deployment, it provides installation technicians with a rock-solid, highly dependable solution that dramatically enhances system reliability.
