The DS1356 contains a six-inch diameter speaker mounted off axis, reducing standing acoustical waves. The compact enclosure includes a convoluted, flame-retardant, acoustical insert to further reduce standing waves and metallic resonance. Dynasound’s DS1356 sound masking speaker is designed for quick and easy installation into open structure architecture and above suspended ceilings. When suspended, the loudspeaker assembly offers a clean appearance with no exposed controls or wiring from below. The DS1356 provides uniform dispersion and is well suited for sound masking, paging and music signals.
