TOA Q-BB-580PW – Square Surface-Mount Back Box

Product Overview

The TOA Q-BB-580PW is a square steel surface-mount back box that lets PC-580 series ceiling speakers be installed on solid surfaces where in-ceiling mounting is not possible. It encloses the rear of the speaker so a flush-mount model can be deployed on a hard ceiling, soffit, or wall. As a TOA surface-mount speaker back box, the Q-BB-580PW is the right accessory for retrofits, concrete decks, and exposed-structure interiors. It gives distributed-audio installs a clean, finished look without a recessed cavity.

The Q-BB-580PW solves a common field problem: a project specifies attractive flush ceiling speakers, but part of the building has no plenum or accessible cavity to recess them into. The square steel enclosure mounts to the surface and accepts a compatible PC-580 series speaker, converting a flush design into a surface-mount assembly. This is frequently needed on poured-concrete ceilings, in renovated spaces with no room above the deck, and in industrial or exposed-structure aesthetics where conduit and boxes are run on the surface. The metal construction protects the rear of the driver and transformer while presenting a tidy, durable face to the room. Because it pairs with the speaker the system already specifies, the acoustic performance and tap settings remain unchanged. Integrators value being able to maintain one speaker model across an entire facility while handling mixed ceiling conditions with the correct back box. The result is consistent coverage and appearance throughout a commercial space. It installs with common hardware and standard low-voltage wiring practice.
