This was written by Mark Eldridge. Richard Clark and David Navone created the thing just for the heck of it. Said to produce an estimated 180db, it did one pulse at the 97 IASCA Finals and hit 162+db. Amazing.

Check it out for yourself.

I've seen pics of that before. It's pretty big. I wonder if they still fire it up every now and then.

Obviously you guys have never watched Back to the Future

When I saw that movie, then I saw the woofer, It did look vaguely familiar.

i wonder what they wrapped the VC with 8ga wire or something. if i knew how to build speakers and everything id build something like that and make an enclosure out of cement and use it as a house sub.

that thing with that much excursion can probaly play 10hz at 150dbs or more. i bet its loudest freq is under 35hz.

so MTX threw money in on this so they could get there name on it? Kinda like the Jackhammer?

The 34" Audiobahn sub has a resonant frequency of 18hz...

There's no way that 60" sub had a resonant frequency higher than 10hz, I guarantee it.

It was installed in that cube van they are standing inside of... and as I understand it, actually blew the cube van apart, ruptured the walls of the van.

I always wondered what happened to that...

Geo, it is still sitting around RC's home, still in near working order. For what I remember, Mark Eldridge is wanting to revamp that truck, and possibly get it working again...but who knows, it would take a huge chunk of change to get it back into working order, but Mark swears he will. We will see.

Might be old but
