Clark Synthesis Tactile Sound U.S.A.

I used the Silver series, which are the 'entry level' on about 200 watts each. They put out over 200 ft. lbs. of force. Its too bad you can't come demo them, though...they are amazing.

These are not the old 'bass shakers' or 'rump shakers' or 'butt kickers' that have been around...these are pro quality, full range, tactile tranducers. They have been using these in themeparks and high end home theater for years.

In a convertible application, like my suburban, they should be really cool, in that since the sound comes through your body, wind noise won't be as big of a problem.
