FEATURES
The Rumbler introduces a revolutionary new concept to audible warning through its ability to interact with most 100/200 W siren amplifiers and provide secondary, low-frequency duplicate tones. Low-frequency tones have the distinct advantage of penetrating solid materials allowing vehicle operators and nearby pedestrians to FEEL the sound waves.
The Rumbler system senses the primary siren tone signal and reduces the signals’ frequency by 75%. It then amplifies the sound through a pair of high output woofers. The system’s timer allows the tone to sound for eight seconds, provides a highly effective warning, and automatically shuts off. The Rumbler is particularly effective when used in dense urban environments with heavy vehicle and pedestrian traffic. A complete Rumbler traffic clearing system consists of an amplifier, with built-in timer and two subwoofers. Vehicle specific mounting hardware is ordered separately. This system can be paired with most 100/200 W emergency siren amplifiers.

Pathfinder Integrated Rumbler Capability ( USE RBKIT1 or RBKIT2)
- Pathfinder + (1) 100 W siren speaker = single-tone, standard PA
- Pathfinder + (2) 100 W siren speaker = dual-tone, standard PA
- Pathfinder + (1) 100 W speaker + (1) or (2) Rumbler woofers = single tone, Rumbler, Enhanced PA
- Pathfinder + (2) 100 W siren speakers + RUMBLER-3 (includes two woofers) = Rumbler, dual-tone siren, standard PA (one channel will Rumble)
- Pathfinder + (1) or (2) Rumbler woofers + (2) 100 W siren speakers + MS4000 = dual-tone, Rumbler, Enhanced PA
