THE LEGENDARY KLEINN LOCOMOTIVE BLAST—REIMAGINED FOR SMALLER RIGS
Don’t let the compact footprint or the price tag fool you; the Model 220 "Mini Beast" truly lives up to its name. This system delivers a deep, authentic Kleinn-style locomotive blast by pairing dual composite ABS wide-bell horns with high-performance zinc alloy drivers. Engineered for drivers who need maximum volume in limited space, these horns provide a thunderous presence with super-versatile mounting capabilities.
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 via 1/4" airline to each horn, this setup allows for unrestricted airflow and a startlingly loud output that rivals much larger systems. Most compact horns share a single valve; the Mini Beast gives each trumpet its own direct line of power for instantaneous, ear-splitting response.
THE COMPACT POWERHOUSE
The Model 220 is the definitive solution for drivers who refuse to compromise on authority, even when mounting space is a luxury. Engineered for smaller trucks, SUVs, and Jeeps, this system bridges the gap between a compact footprint and raw sonic power, proving that a massive train-style rack isn't required to achieve professional-grade volume. It’s called the Mini Beast for a reason—it delivers the perfect fusion of a stealthy, low-profile installation and a "big boy" voice that commands instant respect on the road.
THE VERDICT: The Model 220 Mini Beast is the definitive choice for a professional-grade train horn sound without the mounting headaches of a full-sized rack.
Model 220 "Mini Beast" Train Horns require compressed air and a minimum 1.5-Gallon air tank. Optimal pressure: 140 PSI to 160 PSI.

Find Your Signature Blast
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 in heavy traffic.
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 40,000-lb classic locomotive.
Professional-grade engineering. Legendary Kleinn Performance.
