Each assembly includes a 4" single cone driver, wired transformer, steel enclosure and grille (black or white) along with choice of bridge rail mounting hardware.In general, the purpose of a sound-masking system is to provide for 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. Driver / Transformer 4" 15W single cone driver (paper cone, 10oz. magnet, adaptor ring) and factory-wired 70V transformer with primary taps at 4, 2, 1, .5 and .25 watts (selector switch includes "OFF" position).
