"Yep, Roy used a tool in the demo! It was kinda crowded and complex, but all the subs did well with the sounds - separating kicks, plucks, and whacks. When those La Scalas joined with their horn-loaded bass, they stood out big time. They don't sound like regular subwoofers, not one bit. You can usually spot a DR subwoofer in a system by 'that sound' it makes. These guys really got guts! Seems pretty analog, if Ray's on the money."
