sounds like a good siren

We have ordered one of these... Heard it works most excellently if traffic since the siren causes a vibration that people feel even with music blaring and kids screaming.

EXCELLENT IDEA, cant wait to see it standard protocal on all apparatus. 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 rearview mirror.

I have heard nothing but praise from people that have heard these, they say that you actually feel it before you hear it.

Sounds like a great thing to have. What if someone has there radio in there car turned up really loud?

a guy on a naighboring department has one on his tahoe it works you can feel it before you hear it but when you hear it it has a real deep and sick tone like a regular siren when it is flooded other than the sick sound its pretty cool im thinking about throwing one on my durango

my department just got one to demo and i got the lucky straw it is being installed in the morning on my rig i am looking forward to moving traffic with it

its nice it move cars out of way
