However, the genius of the design was the . Sony bragged about this in their 1991 catalog. The front baffle was actually two sheets of particle board laminated together with a damping sheet in between. This dramatically reduced the "knuckle test"—knock on an SS-U902AV, and you hear a dull thud rather than a hollow box sound. This rigidity allowed the 15-inch woofer to stop and start on a dime.
