no longer for sale

Large white servo subwoofer from the famous, but now defunct, a/d/s company.
"It is servo controlled, which means that there is an accelerometer attached to the cone of the woofer measuring its actual movement and comparing it with the original input signal and making necessary corrections. The result is ultra low distortion. Further, this sub is rated to play down to 17 Hz! below the threshold of human hearing, where most subwoofers fall short."
