The AtlasIED SD72WV is an 8-inch dual-cone ceiling speaker with a built-in volume control, designed for commercial paging, background music, and distributed audio systems. It combines a treated paper cone, 10 oz. ceramic magnet, factory-installed 25V/70.7V line-matching transformer, and a baffle-mounted 5-watt volume control in a complete ceiling speaker assembly.
The transformer provides selectable 0.25, 0.5, 1, 2, and 5-watt taps, while the center-mounted volume control allows convenient local adjustment of speaker level at the ceiling.
A white powder-coated cold-rolled steel (CRS) baffle with concealed mounting studs provides a clean finished appearance for commercial ceiling installations.
Built-In 5-Watt Volume Control
A key difference between the SD72WV and standard SD72W is the center-mounted 5-watt volume control.
The control provides convenient local level adjustment directly at the speaker location and can be incorporated into the installation or removed when it is not required.
This makes the SD72WV particularly useful for commercial applications where individual rooms or areas need local control over ceiling speaker volume.
8-Inch Dual-Cone Speaker
The SD72WV features an 8-inch treated-paper dual-cone loudspeaker with a 10 oz. ceramic magnet.
A 1-inch copper voice coil with a black-anodized aluminum former is designed for effective power dissipation and reliable operation in commercial sound systems.
The speaker provides a specified frequency response of 100 Hz–10 kHz, with an average sensitivity of 97 dB.
Factory-Installed 25V/70.7V Transformer
The SD72WV includes a factory-installed 25V/70.7V line-matching transformer for distributed commercial audio systems.
Available power taps include:
-
0.25 watt
-
0.5 watt
-
1 watt
-
2 watts
-
5 watts
These selectable taps allow installers to configure individual speaker output while managing the total amplifier load in multi-speaker distributed systems.
105° Coverage
The SD72WV provides 105° dispersion at the 2 kHz octave band (-6 dB points), providing broad coverage for ceiling-mounted paging and background music applications.
This coverage pattern makes the speaker suitable for distributed installations where multiple ceiling loudspeakers are positioned throughout a room or facility.
White CRS Ceiling Baffle
The speaker is factory mounted to a cold-rolled steel baffle with a white powder-coat finish.
Concealed speaker mounting studs help provide a clean appearance, while standard mounting provisions allow the assembly to be used with compatible AtlasIED 8-inch ceiling installation accessories.
