The Rumbler introduces a revolutionary new concept to audible warning. This system has the ability to interact with 100/200-watt siren amplifiers and provide secondary, low frequency duplicate tones. Low frequency tones have the distinct advantage of penetrating and shaking solid materials allowing vehicle operators and nearby pedestrians to FEEL the sound waves, and perhaps even see their effects through a shaking rear view mirror.
