AtlasIED GA-15T 15W Weather-Resistant Horn Speaker with 25V/70.7V Transformer

The AtlasIED GA-15T is a high-efficiency 15-watt utility horn speaker designed for clear voice announcements, commercial paging, and intercom systems in demanding indoor and outdoor environments. Featuring a double re-entrant horn design, compression driver, and weather-resistant construction, the GA-15T delivers intelligible speech in areas with elevated background noise.

With 103dB sensitivity and controlled 80° sound dispersion, the GA-15T is well suited for warehouses, manufacturing facilities, schools, gymnasiums, loading areas, and other commercial or industrial locations where announcements must be clearly heard.

The speaker features a built-in 25V/70.7V transformer with selectable power taps, allowing installers to adjust speaker output for distributed paging systems. An 8Ω bypass connection provides an additional option for compatible low-impedance amplifier installations.

Its high-impact plastic horn, adjustable mounting bracket, and color-coded connection leads make the GA-15T a practical solution for commercial paging applications requiring durability, installation flexibility, and dependable performance.

Double Re-Entrant Horn Design for Clear Paging

The AtlasIED GA-15T features a double re-entrant horn design engineered for efficient voice reproduction.

This design helps project speech into the intended listening area, making it particularly useful in environments where machinery, equipment, or other background noise can interfere with announcements.

The GA-15T incorporates a high-efficiency compression driver to provide strong voice output for commercial paging and intercom applications.

With a manufacturer-listed frequency response of 500Hz–3kHz, the speaker focuses on the frequencies important for speech communication.

This makes the GA-15T particularly appropriate for:

• Warehouse paging announcements
• Industrial communication systems
• School and institutional paging
• Loading dock announcements
• Commercial intercom systems
• General-purpose public address applications

While the GA-15T can reproduce audio signals within its operating range, it is primarily intended for speech rather than full-range background music.

High-Efficiency 103dB Sensitivity

The GA-15T provides a manufacturer-listed sensitivity of 103dB.

This high-efficiency design allows the speaker to produce substantial sound output with relatively modest amplifier power.

For commercial paging installations, efficient speaker performance is particularly useful when distributing announcements across multiple locations.

Actual sound levels will depend on the selected transformer tap, amplifier output, mounting location, and surrounding noise conditions.

Controlled 80° Sound Dispersion

The AtlasIED GA-15T features an 80-degree dispersion pattern designed to direct sound toward the intended coverage area.

Compared with wider-dispersion loudspeakers, this controlled pattern can help installers concentrate announcements within specific listening zones.

This is particularly useful in:

• Industrial aisles
• Warehouse work areas
• Loading and receiving areas
• Outdoor gathering locations
• School facilities
• Commercial service areas

Proper speaker positioning is important for achieving consistent coverage and speech intelligibility.

Built-In 25V/70.7V Transformer

The GA-15T includes a built-in transformer designed for compatible 25V and 70.7V distributed audio systems.

For 70.7V operation, the manufacturer specifies the following selectable power taps:

• 0.5 watts
• 1 watt
• 2 watts
• 4 watts
• 8 watts
• 15 watts

These settings allow installers to adjust individual speaker output levels according to the requirements of each listening area.

Lower wattage taps may be suitable for quieter locations, while higher settings provide additional output where greater sound levels are needed.

This flexibility makes the GA-15T useful for commercial paging systems with multiple speakers operating from a common distributed audio amplifier.

The selected power taps must be appropriate for the system voltage, and the combined speaker load must remain within the amplifier's rated capacity.

Convenient Multi-Position Tap Selector

The GA-15T features a multi-position knob switch for selecting the appropriate transformer power tap.

This arrangement simplifies speaker setup and allows installers to configure output levels for the intended application.

The selectable transformer settings are particularly useful in commercial paging systems where different areas may require different announcement levels.

8Ω Bypass for Low-Impedance Applications

In addition to its transformer-based operation, the GA-15T provides an 8-ohm bypass connection.

This allows the speaker to be connected directly to a compatible low-impedance amplifier when the installation does not use a 25V or 70.7V distributed audio system.

The bypass connection provides additional flexibility when integrating the GA-15T into different paging and communication systems.

Important: The 8Ω bypass connection must not be connected directly to a 25V or 70.7V amplifier output.

Weather-Resistant High-Impact Plastic Construction

The AtlasIED GA-15T features a weather-resistant horn constructed from high-impact plastic.

This durable construction makes the speaker suitable for supported outdoor installations and indoor environments where humidity or changing conditions may be present.

The horn's protective design helps support dependable operation in demanding commercial and industrial settings.

Typical installation locations include covered loading areas, warehouses, industrial facilities, and outdoor paging locations.

Installation Note: Weather-resistant does not mean waterproof or submersible. Install the speaker according to AtlasIED's environmental and mounting requirements.

Adjustable Multi-Position Mounting Bracket

The GA-15T includes a multi-position mounting bracket that provides flexibility when positioning the horn speaker.

The bracket allows installers to adjust the speaker's orientation to direct announcements toward the intended listening area.

This makes the GA-15T useful for installations requiring either horizontal or vertical mounting arrangements.

Proper positioning can help improve speech coverage while minimizing unnecessary sound projection into adjacent areas.

Color-Coded Wiring Leads

The AtlasIED GA-15T includes 18-inch, 21-gauge color-coded connection leads.

These leads help simplify wiring and connection identification during installation.

The color-coded design provides a convenient method for identifying the appropriate speaker connections when following the manufacturer's wiring instructions.

This feature is particularly useful for commercial projects involving multiple horn speakers.

Ideal Applications for the AtlasIED GA-15T

The GA-15T is designed for commercial and industrial communication systems requiring efficient voice reproduction.

Common applications include:

• Warehouse paging systems
• Industrial facilities
• Manufacturing plants
• Loading docks
• School paging systems
• Gymnasiums
• Commercial intercom systems
• Outdoor paging installations
• Institutional facilities
• Public address systems
• Commercial communication systems

Its combination of high sensitivity, controlled dispersion, and weather-resistant construction makes it a practical solution for demanding paging applications.
