The AtlasIED HD72W is a preassembled 8-inch commercial speaker and transformer assembly designed for professional paging and background music systems. Featuring a factory-mounted dual-voltage 25V/70.7V transformer, an 8-inch treated-paper cone speaker, and a screw-mounted grille, the HD72W provides a convenient solution for distributed audio installations requiring compatibility with either constant-voltage system.
Ideal for schools, offices, retail stores, warehouses, and commercial facilities, the HD72W combines essential speaker components into a ready-to-install assembly, helping reduce installation time and simplify system integration.
Its 8-inch conventional cone speaker features a 1-inch voice coil and delivers a specified 100 Hz–10 kHz frequency response, making it suitable for speech announcements, general paging, and background music reproduction.
The integrated transformer provides selectable 0.25, 0.5, 1, 2, and 4-watt power taps, allowing installers to adjust speaker output for different areas within a distributed sound system.
With a 24-gauge cold-rolled steel enclosure and textured white epoxy finish, the HD72W offers a professional appearance for commercial audio installations.
Dual-Voltage 25V/70.7V Transformer for Flexible System Integration
One of the most important features of the AtlasIED HD72W is its factory-mounted dual-voltage transformer, which supports compatible 25V and 70.7V distributed audio systems.
This flexibility makes the HD72W a practical choice for facilities using different constant-voltage speaker configurations.
The transformer allows installers to select an appropriate power setting based on the system's design and coverage requirements.
Available power taps include:
-
0.25 watts
-
0.5 watts
-
1 watt
-
2 watts
-
4 watts
With an insertion loss of less than 1.5 dB, the transformer is designed to transfer audio efficiently from the amplifier to the loudspeaker.
Always verify the correct voltage connection and power tap configuration during installation.
Preassembled Design Helps Reduce Installation Time
The HD72W combines the speaker, transformer, and screw-mounted grille into one factory-assembled unit.
This configuration reduces the need to assemble individual speaker components during installation and helps simplify larger commercial paging projects.
For contractors installing multiple speakers throughout a facility, a preassembled speaker assembly can help streamline installation and maintain consistency across the system.
The HD72W uses a 62-8-style baffle and a durable enclosure designed for professional commercial audio applications.
8-Inch Treated-Paper Cone Speaker for Clear Paging
The AtlasIED HD72W incorporates an 8-inch treated-paper cone speaker with a 1-inch voice coil.
Designed for distributed commercial audio applications, the speaker provides a frequency response of 100 Hz–10 kHz, supporting intelligible speech reproduction and general background music.
Its sensitivity ratings of 97 dB peak and 94 dB average make it suitable for paging systems where efficient speaker output is important.
The specified 105-degree dispersion supports sound distribution across appropriate commercial listening areas.
Durable Steel Construction with White Epoxy Finish
The HD72W features a 24-gauge cold-rolled steel enclosure finished in textured white epoxy.
This construction provides a durable housing for commercial speaker installations while maintaining a clean appearance.
The white finish helps the assembly integrate into many commercial interiors, including offices, classrooms, retail spaces, and institutional facilities.
