The backbox mounts above the ceiling surface and surrounds the speaker basket, improving acoustic performance by isolating the driver from open plenum space.

HVAC technicians, low-voltage installers, and general contractors commonly encounter this component during ceiling speaker deployments.\u003c\/p\u003e\u003cp\u003eThe S-551-5 is packaged as a quantity of five units per order, making it practical for multi-room or multi-zone speaker projects. It fits into standard in-ceiling speaker cutouts and is appropriate for drop-ceiling and drywall ceiling installations where speaker enclosures are required.
