Model HK9-Slimline: Universal Onboard Air & Triple Train Horn System
THE UNDISPUTED KING OF THE ROAD
When the situation demands more than just a loud horn, the Demon 730 stainless steel horns dominate the road! Delivering a sonic roar that cuts through sirens, heavy machinery, and chaotic traffic, these precision tuned steel horns are the ultimate train horn solution. Engineered to move massive volumes of air, the 730 provides the deep, earth-shaking rumble of an authentic 40,000-lb locomotive.
XCR 2.0™ EXTREME DURABILITY
Featuring our signature XCR 2.0™ salt-spray resistant coating, the Demon 730 thrives in the harshest environments. Whether faced with coastal salt air or off-road mud, these horns are built to maintain their professional-grade finish and startling output for the long haul. The stainless steel construction ensures that the internal components won't succumb to the corrosion that destroys lesser horns.
MODULAR MOUNTING FLEXIBILITY
While the Demon 730 comes mounted on a heavy-duty flat rack, it offers maximum installation flexibility. Each individual trumpet can be removed from the rack and mounted separately to accommodate even the tightest installation requirements on trucks, SUVs, or Jeeps. This modular architecture allows you to tuck the massive 6" to 7" bells into locations where a fixed-rack system simply won't fit.
BOOST YOUR BLAST: 30% MORE OUTPUT
Unleash the full fury of your Demon™ 730 Train Horns!
Experience the Demon™ 730 Horns in all their glory! The Ultra BlastMaster™ (6890) re-engineers your system’s architecture, maximizing airflow to deliver a devastating, high-decibel blast. It’s simple physics: more air equals more output. We ditched the standard 3/8” lines in favor of massive, dedicated 1/2” airlines leading to three High-Flow VX6003 brass solenoids—one for every individual horn.
This isn't just an upgrade; it’s a shocking twist on a classic, delivering soul-shaking locomotive blasts that command immediate attention. Overwhelm the senses and dominate the streets with the absolute peak of train horn intensity at your fingertip.
TOO LOUD? TOO BAD!
