This was the first year they came out. Our Halloween Party was a debut for them. Delivery was 3 days before; Install was 2 days before, that night blew out the W Bins; 4 Gauss drivers were put in two seats on a plane for "immediate" delivery, I had to go to the airport and haul them off the plane; Installed the Gauss' the second I got back and fired them up using the same Crown amp. WOW!!! They sounded incredible. With 1 day to spare. I had used Gauss before and had always liked them.
