The AtlasIED SD72W is an 8-inch dual-cone ceiling speaker designed for commercial paging, background music, and distributed audio systems. It combines a treated paper cone, 10 oz. ceramic magnet, and factory-installed 25V/70.7V line-matching transformer in a complete assembly for recessed ceiling installations.

The included transformer provides selectable 0.25, 0.5, 1, 2, and 5-watt taps, allowing the SD72W to be configured for a variety of distributed commercial sound applications.

A white powder-coated cold-rolled steel (CRS) baffle provides a clean finished appearance, while concealed loudspeaker mounting studs help simplify installation.

8-Inch Dual-Cone Speaker

The SD72W uses 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 provides effective power dissipation and reliable operation for commercial paging and background music systems.

The speaker provides a specified frequency response of 55 Hz–8 kHz (±5 dB) and an average sensitivity of 97 dB.

Factory-Installed 25V/70.7V Transformer

The SD72W includes a factory-installed dual-voltage 25V/70.7V line-matching transformer for use in distributed commercial audio systems.

Available power taps include:

• 0.25 watt
• 0.5 watt
• 1 watt
• 2 watts
• 5 watts

These selectable transformer taps allow installers to balance speaker output and amplifier load requirements across multi-speaker distributed audio systems.

105° Coverage

The SD72W provides 105° dispersion at the 2 kHz octave band (-6 dB points), providing broad coverage for ceiling-mounted paging and background music applications.

This makes it well suited for installations where multiple ceiling speakers are distributed throughout a room or facility.

White CRS Ceiling Baffle

The SD72W includes a cold-rolled steel baffle finished in white powder-coat epoxy for integration into commercial ceilings.

Concealed mounting studs help provide a clean finished appearance once the speaker assembly is installed.
