Model 220: "Mini Beast" Dual Black ABS Train Horns - Dual Vortex™ 4 Model 307 Solenoids

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.

WHY CHOOSE THE "MINI BEAST" 220?

  • 151.8 dB of Pure Authority: Don't let the "Mini" tag fool you. This system produces a bone-rattling, high-decibel blast designed to be felt as well as heard.
  • "Fit Anywhere" Modular Versatility: Because the two horns are independent units, you have total mounting freedom to tuck them into tight corners or separate sides of a bumper.
  • Unrestricted Airflow Design: Includes two dedicated Vortex™ 4 solenoids. Each horn gets its own direct air path fed by separate 1/4" airlines, resulting in zero lag.
  • Legendary Locomotive Tone: Wide-bell ABS trumpets paired with heavy-duty zinc drivers deliver the deep, authentic Kleinn harmonic chord that mimics a real freight train.
  • Built for the Long Haul: High-impact, weather-resistant ABS is engineered to withstand road debris, mud, and extreme weather without losing quality.

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.
