FedSig Rumbler Low Frequency Siren

Shatter the acoustic barrier of heavily insulated civilian vehicles with the Federal Signal Rumbler Low Frequency Siren. Modern cars are virtually soundproof, rendering traditional high-pitched sirens dangerously ineffective at busy intersections. The Rumbler system solves this by sensing the primary siren tone, dropping the frequency by 75%, and amplifying it through specialized woofers. The result is a deep, 182 Hz to 400 Hz tone that penetrates solid glass and steel, forcing distracted drivers and pedestrians to physically feel the sound waves vibrating through their seats and steering wheels.

Key Features & Upfitter Specs

Performance: Generates a highly penetrative, low-frequency (182-400 Hz) sound wave that supplements the vehicle's primary 100/200W siren.
Compatibility: Universally designed to interact seamlessly with most major 100/200-watt emergency vehicle siren amplifiers on the market.
Activation: Engages rapidly via the vehicle's steering wheel horn ring or a dedicated momentary switch for instant intersection clearing.
Safety Timer: Includes an adjustable automatic shut-off timer (typically 8 seconds) to prevent prolonged exposure and system overheating.
Output: The amplifier drives 80 watts of raw power to the specialized Rumbler woofers (speakers and vehicle-specific brackets sold separately).
