Model HK5: Universal "Mini Beast" Dual Train Horns System | ABS Trumpets

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.

WHY CHOOSE MODEL HK5?

  • The Mini Beast™ (220) Dual Train Horns: High-impact ABS plastic trumpets and Heavy-duty Zinc Alloy Driver, these horns are designed for a loud, authentic locomotive sound with maximum durability and a lightweight design.
  • Industry-Leading Submersible Waterproof Compressor: Drive with total confidence through river crossings or monsoons by drawing air from inside the vehicle using the snorkel kit provided with the compressor.
  • Maximum Output: Consistent 150 PSI pressure and 1.76 CFM flow rate make this kit perfect for high-impact, loud, and authoritative horn performance (50% duty-cycle).
