The AtlasIED APF-15T is a professional 15-watt flanged horn speaker designed for commercial paging, voice announcements, and emergency notification applications where speech intelligibility and reliable performance are essential. Part of the AtlasIED Omni-Purpose® speaker series, the APF-15T combines a high-efficiency compression driver with durable metal construction and flexible mounting options.
Featuring a built-in 25V, 70.7V, and 100V transformer, the APF-15T integrates into distributed audio systems commonly used in schools, warehouses, industrial facilities, commercial buildings, and public address installations.
Its double re-entrant horn design provides efficient voice and tone reproduction, while the flanged mounting configuration allows installation in compatible walls, ceilings, panels, and speaker enclosures.
With a 15-watt power rating, 104 dB sensitivity, and 95-degree dispersion, the AtlasIED APF-15T delivers dependable performance for commercial sound systems requiring clear, intelligible announcements.
High-Efficiency Horn Design for Clear Voice Announcements
The AtlasIED APF-15T incorporates a double re-entrant horn design engineered for efficient reproduction of speech and signaling tones.
This design makes the speaker particularly useful in environments where announcements must remain understandable despite background noise.
Typical applications include:
- Commercial paging systems
- Industrial voice announcements
- School notification systems
- Warehouse paging
- Public address installations
- Voice and tone signaling
With a frequency response of 600 Hz to 14 kHz, the APF-15T is optimized for speech-oriented audio applications rather than full-range background music reproduction.
Built-In 25V, 70.7V and 100V Transformer
The APF-15T includes an integrated transformer for use with compatible constant-voltage distributed audio amplifiers.
Its transformer configuration supports:
- 25V distributed audio systems
- 70.7V distributed audio systems
- 100V distributed audio systems
For 70.7V installations, the manufacturer lists the following power taps:
1W, 2W, 3.8W, 7.5W, and 15W
These selectable settings allow installers to balance speaker output levels and amplifier loading according to system requirements.
The integrated Vari-Tap® control provides convenient wattage and impedance selection.
When designing a distributed audio system, the combined speaker tap settings should remain within the amplifier's available output capacity.
Flange or Recessed Mounting Options
The AtlasIED APF-15T is designed for flexible installation in commercial audio environments.
Its flanged construction allows mounting to compatible:
- Wall panels
- Ceiling panels
- Interior walls
- Exterior walls
- Speaker baffles
- Equipment enclosures
The speaker can also be recessed into a suitable opening.
For the APF-15T, AtlasIED specifies a 5½-inch-deep opening for recessed installation.
Compatible AtlasIED L20 Series enclosures and appropriate mounting accessories may be used where required by the installation.
The manufacturer also identifies the FAMT-6 mounting kit for certain 8-inch baffle and enclosure configurations.
Mounting accessories are sold separately unless otherwise specified.
Durable Metal Construction
The APF-15T features metal construction designed to withstand demanding commercial environments.
Its vandal-resistant design helps protect the speaker against physical abuse, while its grey baked-epoxy finish provides a durable exterior.
The weather-resistant construction and enclosed wiring terminals can eliminate the need for a separate backbox in suitable installations.
However, installation requirements should always be evaluated based on the environment, applicable electrical codes, and the manufacturer's instructions.
