The AtlasIED C5AT72 is an economical 8-inch commercial loudspeaker with a factory-installed 4-watt transformer, designed for paging, background music, and distributed audio systems. Combining the AtlasIED C5A dual-cone speaker with an LT-72 line-matching transformer, this assembly provides a cost-effective solution for commercial, industrial, and institutional sound installations.
Featuring a treated-paper cone, 1-inch copper voice coil, and black-anodized aluminum voice coil former, the C5AT72 is designed to deliver reliable speech reproduction and background music performance.
With a 100Hz–10kHz frequency response, 93dB average sensitivity, and 105° dispersion, this speaker is suitable for offices, retail stores, schools, warehouses, and other commercial environments.
The factory-mounted transformer supports 25V and 70.7V distributed audio systems, while compatibility with a variety of AtlasIED baffles and enclosures provides flexibility for different installation requirements.
Economical 8-Inch Speaker for Commercial Audio
The AtlasIED C5AT72 incorporates the C5A loudspeaker, an industry-standard design intended for general-purpose commercial sound applications.
Its 8-inch treated-paper cone features a curvilinear design that helps reduce harmonic distortion and provide smooth sound reproduction.
The speaker also includes a full 1-inch copper voice coil with a black-anodized aluminum former designed to improve heat dissipation.
These features make the C5AT72 a practical choice for distributed audio installations where dependable performance and economical equipment selection are important.
The C5A loudspeaker has a 15-watt power rating, while the included transformer provides selectable taps up to 4 watts.
Factory-Installed LT-72 Transformer
The AtlasIED C5AT72 includes a factory-mounted LT-72 line-matching transformer for use with compatible 25V and 70.7V constant-voltage audio systems.
The transformer provides four selectable power taps:
- 0.5 watts
- 1 watt
- 2 watts
- 4 watts
These settings allow installers to adjust individual speaker levels based on the requirements of each listening area.
Lower tap settings may be appropriate for quieter background music applications, while higher settings provide additional output where needed.
The factory-installed transformer also eliminates the need to purchase and mount a separate transformer during installation.
Important: Although the loudspeaker itself is rated for 15 watts, the installed LT-72 transformer has a maximum selectable tap of 4 watts.
Clear Paging and Background Music Reproduction
The AtlasIED C5AT72 provides a 100Hz–10kHz frequency response with sensitivity ratings of 96dB peak and 93dB average.
These performance characteristics make the speaker suitable for speech-focused distributed audio systems and general background music applications.
Its 105° dispersion angle helps distribute sound throughout the listening area.
For installations using multiple loudspeakers, proper speaker spacing and transformer tap selection can help achieve balanced audio coverage across the facility.
Actual coverage will depend on ceiling height, room acoustics, and system design.
Compatible with AtlasIED Baffles and Enclosures
The C5AT72 is designed to mount with a wide selection of compatible AtlasIED round and square speaker baffles and enclosures.
This allows installers to select mounting components based on the appearance, ceiling construction, and functional requirements of the project.
Unlike a complete ceiling speaker package, the C5AT72 is supplied as a loudspeaker and transformer assembly.
The appropriate baffle, enclosure, and mounting hardware should be selected separately unless specifically included in the product offering.
This flexibility makes the C5AT72 useful for new commercial installations and replacement applications.
