THE LEGENDARY KLEINN LOCOMOTIVE BLAST—REIMAGINED FOR SMALLER RIGS
Don’t let the compact footprint or the price tag fool you; the Model HK5 "Mini Beast" truly lives up to its name. This system delivers a deep, locomotive, Kleinn-style blast by pairing dual composite ABS wide-bell horns with high-performance zinc alloy drivers. These horns provide the train horn blast with super versatile mounting capabilities; each horn mounts individually for a fit in virtually any application.
UNRESTRICTED AIRFLOW FOR MAXIMUM VOLUME
To ensure every decibel is accounted for, each horn is equipped with its own Vortex™ 4 (307) solenoid. By providing a dedicated air path of 1/4" airline to each horn, this setup allows for unrestricted airflow and a startlingly loud output that hangs with much larger systems.
THE COMPACT POWERHOUSE
The HK5 is the ultimate solution for vehicles where mounting space is at a premium—such as smaller trucks, SUVs, or Jeeps—but a commanding "get out of the way" presence is non-negotiable. This system bridges the gap between size and strength by pairing our industry-exclusive waterproof compressor with a larger capacity 1.5-Gallon tank. The Result? A consistent 150 PSI of pressurized air that fuels the deep, locomotive-style rumble only a true train horn can produce. Now you can command the road with the authentic Kleinn blast without the need for a massive, space-hungry footprint and with the durability that our clients expect.
THE VERDICT:The Model HK5 "Mini Beast™" is the definitive choice for drivers who demand a professional-grade blast and rock-solid reliability in a package footprint sized to fit almost any compact truck or utility vehicle.
The Screamer
Engineered for "Emergency Vehicle" authority. This series delivers a sharp, high-frequency blast designed to cut through ambient noise instantly. With 3.5" bells, these horns produce a piercing scream that commands attention.
The Deep Rumble
Don’t just make noise—make an impact. Engineered with massive 6-7" bells, our Train Horns move huge volumes of air to create a deep, earth-shaking rumble. This is the authentic tone of a classic 40,000-lb locomotive.
Professional-grade engineering. Legendary Kleinn Performance.
