My dream exactly!
anyone familiar with Concept Design?
Out.
Did you wake up when she pulled out the schematics book too!

WHATS THE STORY ON THIS?
40+ years of sacrifice...and for what???
He'll need 2 for stereo!
Ron
this is the mtx-1,000,000
an effort for max sound pressure levels
tested in a masonary structure,
then mounted in a truck,
the trucksides* bending,reduced
the spls
*a new word?
I'm serious - Leif, tell me (at least) details about this thing and what it's for? So far all I see is a picture with no details.
I don't understand why no one else here is asking???
Sorry but I have no information about it. Just found the picture on a norwegian audio discussion forum. And wanted to share the picture of this mega woofer to you all.
But if someone have some info, please come on and put it down for us to read.
... and two 18" super tweeters.

copy+paste -
A single 60-inch (1,500 mm) diameter subwoofer driver was designed by Richard Clark and David Navone with the help of Dr. Eugene Patronis of Georgia Institute of Technology. The driver was intended to break sound pressure level records when mounted in a road vehicle, calculated to be able to achieve more than 180 dBSPL. It was built in 1997, driven by DC motors connected to a rotary crankshaft somewhat like in a piston engine. The cone diameter was 54 inches (1,400 mm) and was held in place with a 3-inch (76 mm) surround. With a 6-inch (150 mm) peak-to-peak stroke, it created a one-way air displacement of 6,871 cubic inches (112,600 cm3).[79] It was capable of generating 5–20 Hz sine waves at various DC motor speeds—not as a response to audio signal—it could not play music. The driver was mounted in a stepvan owned by Tim Maynor but was too powerful for the amount of applied reinforcement and damaged the vehicle.[79] MTX's Loyd Ivey helped underwrite the project and the driver was then called the MTX "Thunder 1000000" (one million).[80] Still unfinished, the vehicle was entered in an SPL competition in 1997 at which a complaint was lodged against the computer control of the DC motor. Instead of using the controller, two leads were touched together in the hope that the motor speed was set correctly. The drive shaft broke after one positive stroke which created an interior pressure wave of 162 dB. The Concept Design 60-inch was not shown in public after 1998.[81]
