• High-Efficiency Voice Projection: The Kentech HN158 is a rugged, heavy-duty rectangular reflex horn speaker flare engineered for long-range voice paging, public address announcements, and outdoor siren alert dispatch systems.
• All-Aluminium Weatherproof Build: Fabricated with a premium spun aluminium cone housing that stands up to severe environmental conditions, including direct sunlight heat, heavy rain, and coastal corrosion, making it far more durable than standard plastic alternatives.
• Optimal Directivity Profile: The distinct 15" x 8" rectangular (square type) flare shape is geometrically optimized to throw mid-range vocal frequencies across a wide horizontal plane while narrowing vertical spill, focusing the audio directly at the target crowd area.
• Sturdy Universal Mounting Bracket: Outfitted with a heavy-duty, adjustable U-shaped metal mounting yoke bracket that allows installers to securely bolt the unit to walls, support columns, or structural pipe grids and tilt it to the exact angle required.
• Driver Compression Versatility: Built to accept standard screw-on horn driver units (typically 1-3/8" threaded connections), allowing engineers to pair the horn flare with their choice of 100V line transformers or low-impedance high-power drivers.

Features

• All-Metal Environmental Deflector: The core internal sound-distribution reflex center is built completely out of treated metal alloys to maintain maximum projection efficiency and clarity under thermal stress.
• Enhanced Acoustic Gain: The precision exponential expander shape maximizes sound pressure levels (SPL), allowing low-wattage system feeds to translate into exceptionally loud, clear outdoor announcements.
• Anti-Vibration Edge Gasket: Features a reinforced edge profile along the main flare rim that suppresses body resonance, ensuring the speaker doesn't buzz or distort when driven at maximum capacity.
• Corrosion-Resistant Grey Powder Coat: Finished in an industrial light grey protective powder coating that reflects thermal radiation and blends seamlessly into factory ceilings, building facades, and sports grounds.
• Flexible Orientation Setup: Can be mounted horizontally for wide coverage across sports fields, or vertically to push sound down narrow corridors, factory aisles, and warehouse paths.
