The DS1390B is a compact and efficient sound masking and paging loudspeaker designed for modern commercial environments where space is limited. With its ability to fit into floor cavities as shallow as 1.75 inches or ceiling plenums, it provides unmatched installation flexibility. The DS1390B uses dual horizontally opposed drivers to deliver uniform 360-degree dispersion, ensuring consistent sound coverage across the space.
The loudspeaker includes an internal 70V transformer with selectable power taps, allowing seamless integration into distributed paging and masking systems. For ceiling installations, the included tile bridge accessory provides secure and convenient mounting.
Certified to meet UL 1480, UL 2043, and CSA standards, and rated for use in air handling spaces, the DS1390B delivers safe, reliable performance. Its discreet, low-profile design ensures it blends into any environment while maintaining excellent audio quality.
Note: Formerly sold under the Dynasound brand, the DS1390B continues to offer the same quality and features.
