Atlas Sound PD-5VT – 40W 70V Compression Driver for Large Format Horns

Product Overview

The Atlas Sound PD-5VT is a 40-watt compression driver for large format horn speakers, equipped with a built-in multi-tap 70.7V line-matching transformer for distributed audio paging and sound reinforcement applications. As a 40-watt 70V compression driver for large format paging horns, the PD-5VT is designed for outdoor and indoor high-SPL installations requiring a durable, weather-resistant driver that mounts to standard 1-3/8"-18 threaded horn couplings. Common deployment contexts include outdoor paging systems, parking facilities, sports complexes, industrial facilities, and government campus PA systems where a compression driver for 70V horn speaker systems is required.

Product Description

The PD-5VT features a 2-inch voice coil wound on a ceramic magnet assembly, optimized for driver efficiency and power handling in high-SPL horn applications. The built-in transformer is varnish-impregnated and tropic-sealed for moisture and temperature resistance, supporting outdoor and high-humidity indoor environments. The transformer provides primary taps at 2.5, 5, 10, 20, and 40 watts on the 70.7V line, making it compatible with standard commercial 70V amplifiers across a wide range of power configurations. The unit is also adaptable to 25-volt audio system operation by selecting the appropriate impedance terminal. Plane wave frequency response spans 190Hz to 4.2kHz, covering the speech intelligibility range critical for paging and announcement systems. Average sensitivity is 111.2dB from 190Hz to 4.2kHz, one of the highest sensitivity ratings in the Atlas Sound driver lineup, enabling high SPL output from relatively modest amplifier power. The driver mounts to any large format horn terminating in a standard 1-3/8"-18 male coupling thread, providing broad compatibility with Atlas Sound and third-party horn assemblies. Wiring terminals are corrosion-resistant screw-type connections, protected by a transparent impact-resistant plastic cover that also provides strain relief for interconnecting cable. The unit’s grey baked epoxy finish and environment-resistant construction are suitable for both indoor and outdoor deployment. The PD-5VT meets BAA and TAA compliance requirements and holds an IP56 environmental rating for dusty and wet environments. It carries a 60-month warranty.

Frequently Asked Questions

Q: Which horn speakers is the PD-5VT compatible with?

A: The PD-5VT mounts to any large format horn that terminates in the standard 1-3/8"-18 male coupling thread, including AtlasIED AH-series, FS-series, and many third-party horn assemblies. The horn is sold separately.

Q: Can the PD-5VT be used outdoors?

A: Yes. The IP56 environmental rating, tropic-sealed transformer, and grey baked epoxy finish make the PD-5VT suitable for outdoor and high-humidity indoor installations including covered walkways, stadiums, and industrial yards.

Q: Does the PD-5VT support 25-volt audio systems?

A: Yes. The transformer is adaptable to 25V system operation by selecting the appropriate impedance terminal, broadening compatibility beyond standard 70.7V systems.

Q: What is the maximum SPL output?

A: With an average sensitivity of 111.2dB (1W/1m, 190Hz-4.2kHz), the PD-5VT at full 40W power produces approximately 127dB SPL at 1 meter, making it well-suited for large outdoor paging areas requiring broad coverage at high levels.

Q: Is the PD-5VT BAA/TAA compliant for government projects?

A: Yes. The PD-5VT carries Buy American Act (BAA) and Trade Agreements Act (TAA) compliance markings, qualifying it for government and federally-funded commercial facility projects.

Q: Is there a low-frequency protection filter available for horn drivers?

A: AtlasIED offers the TSD-HF11 high-pass filter designed to protect paging horn drivers from low-frequency damage. This is recommended for systems where low-frequency content may reach the horn driver from the amplifier or signal chain.
