The SM410A UL Listed sound masking speaker ships completely assembled and ready for installation. Each assembly includes a 4" 15W single cone driver, 70V wired transformer, steel enclosure and grille (black or white) along with choice of hanger/chain or bridge rail mounting hardware. 

In general, the purpose of a sound masking system is to provide greater conversational privacy and productivity in open office environments by adding ambient noise and shaping the signal to mask speech. The signal is fed from a generator with an amplifier to sound masking speakers that are typically positioned above finished lay-in tile ceilings in plenum space; however, speaker assemblies with a white finish are sometimes specified for use in open architecture truss type ceilings.
