The AtlasIED AP-15TC is a high-efficiency, 15-watt commercial horn loudspeaker designed for clear voice paging, public address announcements, and audible signaling in indoor and outdoor environments. Featuring a weather-resistant enclosure, integrated multi-tap transformer, and versatile mounting bracket, the AP-15TC provides reliable speech reproduction for warehouses, schools, factories, commercial buildings, and other facilities requiring dependable communication.
Unlike the standard 8-ohm AP-15, the AP-15TC includes a built-in transformer for 25V, 70.7V, and 100V distributed audio systems. This makes it suitable for commercial paging installations where multiple horn speakers are connected to a compatible constant-voltage amplifier.
Its distinctive square-bell design and beige epoxy finish provide a durable, professional appearance for installations where clear announcements and dependable operation are essential.
High-Efficiency Horn Speaker for Clear Voice Paging
The AtlasIED AP-15TC uses a double re-entrant horn design with a high-efficiency compression driver to project speech and signaling tones across large areas.
With 15 watts of continuous power handling and a nominal frequency response of 400 Hz to 14 kHz, the AP-15TC is engineered for intelligible voice reproduction rather than full-range background music.
The speaker delivers an average sensitivity of 106 dB at 1 watt/1 meter and provides a nominal 70° dispersion angle, allowing installers to direct announcements toward the intended listening area.
This makes the AP-15TC particularly useful in noisy commercial and industrial environments where ordinary ceiling speakers may not provide sufficient voice projection.
Built-In Transformer for 25V, 70.7V, and 100V Paging Systems
The AP-15TC features an integrated line-matching transformer for use with commercial distributed audio systems.
Its Vari-Tap® transformer selection system allows installers to adjust speaker power according to the requirements of the installation.
Available 70.7V power taps include:
- 1 watt
- 2 watts
- 3.8 watts
- 7.5 watts
- 15 watts
Lower wattage settings are useful when multiple speakers share an amplifier and less output is required in a particular area.
Higher settings provide additional output for locations with greater ambient noise or more demanding coverage requirements.
The transformer also supports compatible 25V and 100V systems, providing flexibility for different commercial paging installations.
Weather-Resistant Construction for Indoor and Outdoor Use
The AtlasIED AP-15TC is designed for installations where exposure to changing environmental conditions is a concern.
Its enclosure combines metal and ABS plastic components with a durable beige epoxy finish.
The weather-resistant construction makes the speaker suitable for protected outdoor locations as well as demanding indoor commercial environments.
Typical installations include loading docks, industrial facilities, covered walkways, warehouses, and other locations requiring reliable voice announcements.
Omni-Purpose® Mounting Bracket for Flexible Installation
The AP-15TC includes AtlasIED's Omni-Purpose® mounting bracket, which allows installers to adjust the speaker's horizontal and vertical positioning.
The bracket supports conventional surface mounting and provides provisions for strap mounting to structural supports such as I-beams or pillars.
This flexibility allows the horn to be directed toward the desired coverage area while simplifying installation.

What Amplifier Does the AtlasIED AP-15TC Require?
The AP-15TC requires a compatible 25V, 70.7V, or 100V constant-voltage amplifier.
The appropriate amplifier depends on the number of horn speakers, the selected transformer taps, and the installation's total power requirements.
For example, ten AP-15TC speakers configured at 7.5 watts each create a combined speaker load of 75 watts. The amplifier should provide sufficient output capacity for that load, including an appropriate design margin.
The AP-15TC is intended primarily for speech paging and signaling rather than full-range music reproduction.
