Cambridge DS1339W 70V plenum loudspeaker (White) - 911.0709.900
Product Overview
The Cambridge Sound DS1339W (part number 911.0709.900) is a white 70V plenum loudspeaker with a 5.25-inch driver mounted on axis. It serves sound masking, paging, and music distribution in open structure facilities and above suspended ceilings. An internal 70.7-volt transformer with rotary volume control handles level setting on distributed lines. Four-point suspension keeps installation and leveling fast.
Product Description
The DS1339W combines a compact enclosure with a convoluted, flame-retardant acoustical insert that eliminates standing waves and metallic resonance. This treatment yields uniform dispersion appropriate for broadband masking noise, voice paging, and background music. Suspended in exposed-structure architecture, the white assembly presents a clean appearance with no controls or wiring visible from below — a practical match for open ceilings painted in lighter finishes. The internal 70.7V transformer with rotary volume control lets installers set zone levels without adding external attenuators. ETL listing to UL 1480A and UL 2043 supports use in air-handling plenum spaces. Browse companion speakers and hardware in the Cambridge Sound collection at Creation Networks.
