Trying to bust the myth that you can destroy a car with sound...

These yahoos mount a crankshaft to the drive shaft of an oldsmobile. This provides the linear motion for a large 4 foot or so subwoofer.

What's problem?

I'm just thinking....20 hz wave = sub has to move up and down 20 times a SECOND. That means the drive shave is 1200 RPM.

Doesn't that seem a litte fast for a drive shaft? maybe I'm off here, but I wouldn't think the differential would reduce the gearing that much.

-edit- crap, wrong forum.
 
They actually got it to 16Hz @ 164db SPL before it ate itself.

It blew the sunroof, so further pressure was vented.

They sent their guy to FL for a "loudest car audio system" rally.

Pretty good episode. I think they should have found a better suspension system for their cone though ...

FWIW
