The AtlasIED HLE/MLE-32 Spun Aluminum Projector Horn is a professional industrial loudspeaker accessory designed for use with compatible AtlasIED HLE and MLE Series explosion-proof compression drivers. Featuring rugged spun aluminum construction and a 95° circular sound dispersion pattern, the HLE/MLE-32 provides efficient sound distribution for industrial paging, voice announcements, and electronic signaling systems in appropriately classified hazardous locations.
Designed for demanding industrial communication applications, the AtlasIED HLE/MLE-32 explosion-proof projector horn combines the efficiency of a reflex-style projector with a circular coverage pattern. When paired with an approved compression driver, it helps deliver clear, intelligible voice communication in industrial processing facilities, manufacturing plants, and other environments requiring specialized hazardous-location audio equipment.
The HLE/MLE-32 is compatible with several AtlasIED HLE and MLE Series compression drivers, including the AtlasIED MLE-3T 30W Explosion-Proof Compression Driver, which features a factory-installed 70.7V transformer.
Important: The HLE/MLE-32 is a projector horn only. The explosion-proof compression driver is sold separately and must be ordered to complete the loudspeaker assembly.
95° Circular Sound Dispersion for Industrial Paging
The AtlasIED HLE/MLE-32 features a 95° circular dispersion pattern, designed to provide sound coverage across a defined industrial listening area.
Unlike wide-angle horns that distribute sound differently across horizontal and vertical planes, the HLE/MLE-32 provides a circular coverage pattern for applications where a more uniform directional sound field is desired.
This makes it suitable for industrial communication systems requiring controlled sound distribution in processing areas, equipment locations, production facilities, and other industrial environments.
The horn's reflex-style projector design supports efficient acoustic output when paired with an approved AtlasIED explosion-proof compression driver.
Durable Spun Aluminum Construction
The HLE/MLE-32 is manufactured from spun aluminum, providing a durable horn structure for professional industrial audio installations.
Its construction is intended for use with compatible explosion-proof compression driver assemblies in environments where equipment must meet specific hazardous-location requirements.
The aluminum bell design combines mechanical durability with a circular sound coverage pattern, making the HLE/MLE-32 a practical option for industrial voice paging and audible signaling systems.
For installations requiring wider horizontal coverage, AtlasIED also offers the HLE/MLE-30 polycarbonate projector horn, featuring a 120° × 60° dispersion pattern.
Designed for Approved Hazardous-Location Communication Systems
The AtlasIED HLE/MLE-32 is designed for use with compatible HLE and MLE Series explosion-proof compression drivers in approved hazardous-location loudspeaker assemblies.
These systems may be specified for industrial facilities where flammable gases or vapors create special electrical equipment requirements.
AtlasIED identifies the HLE/MLE-30 and HLE/MLE-32 as the approved projector horn models UL Listed for use with the HLE and MLE Series explosion-proof drivers.
The final hazardous-location suitability depends on the selected driver, the complete approved assembly, the area's classification, and compliance with applicable installation requirements.
Safety Notice: The HLE/MLE-32 horn should not be considered an independently operating explosion-proof loudspeaker. It must be installed with a manufacturer-approved driver and in accordance with the applicable certification and installation instructions.

Compatible AtlasIED Explosion-Proof Compression Drivers
The AtlasIED HLE/MLE-32 projector horn is designed for use with approved HLE and MLE Series explosion-proof compression drivers. Selecting a compatible driver allows the horn to become part of a complete industrial paging or audible signaling loudspeaker assembly.
Need a 30W Explosion-Proof Compression Driver?
The AtlasIED MLE-3T 30W Explosion-Proof Compression Driver features a factory-installed 70.7V transformer with selectable power taps of 1.8W, 3.7W, 7.5W, 15W, and 30W.
When paired with the HLE/MLE-32 projector horn, the MLE-3T provides 110 dB sensitivity and 95° circular sound coverage for industrial paging and communication applications.
The MLE-3T is an excellent companion product for customers designing compatible 70.7V industrial paging systems.
The MLE-3T driver is sold separately.
Other Compatible AtlasIED Drivers
The HLE/MLE-32 also mounts to the following AtlasIED explosion-proof compression drivers:
-
HLE-1 and HLE-1T
-
HLE-3 and HLE-3T
-
MLE-1 and MLE-1T
-
MLE-3
All driver-and-horn combinations must comply with the manufacturer's applicable hazardous-location certification and installation requirements.
Need Wider Sound Coverage?
AtlasIED HLE/MLE-30 Wide-Angle Explosion-Proof Projector Horn
The AtlasIED HLE/MLE-30 Polycarbonate Projector Horn offers a 120° × 60° dispersion pattern, making it an alternative for applications requiring broader horizontal coverage.
Both the HLE/MLE-30 and HLE/MLE-32 are designed for use with compatible AtlasIED explosion-proof compression drivers, including the MLE-3T.
Choose the HLE/MLE-30 for its wide-angle coverage pattern or the HLE/MLE-32 for its 95° circular dispersion, based on the sound system's coverage requirements.
Both projector horns are sold separately from the compression drivers.
