Federal Signal Rumbler for emergency vehicles introduces a revolutionary new concept to audible warning through its ability to interact with most 100/200-watt 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.
