Lowell SM410A-BR 4" Sound Masking Speaker With Enclosure and Grille

The Lowell SM410A-BR is an above-ceiling sound masking speaker designed for installed audio environments where speech privacy and acoustic comfort are priorities. It ships as a complete assembly, combining a 4-inch 15W single cone driver with a 70V line transformer, a protective grille, an enclosure, and factory-mounted bridge rails, reducing field labor and simplifying above-tile deployment in commercial installations.

Integrators specifying sound masking systems for offices, healthcare facilities, open-plan workspaces, or government environments will find this speaker ready to drop into a grid ceiling with minimal on-site assembly. The 70V distributed audio architecture supports long cable runs and multi-speaker zoning without impedance matching complications, making it compatible with standard commercial sound masking controllers and amplifier systems.

Because the bridge rails are factory-mounted rather than field-installed, the SM410A-BR is made to order and is non-returnable. It is priced per unit and must be ordered in multiples of four, consistent with standard ceiling grid tile layouts. Specifying this speaker avoids the inconsistency of field-assembled masking installations and ensures every unit ships with identical factory configuration.
