I just went to see Papa Roach and they had 3 svt cabs laid down and stacked sideways on top of each other on BOTH sides of their drummer. That's a total of 48 10 inch speakers. It really made the 2 Marshall stacks each guitar player had seem small. Visually it was cool and it makes you wonder what it might sound like..........in my garage.......or down the street! I had seen old ACDC footage where Cliff williams did this as well with 3 810 stacked sideways, but I havent seen it since. I have seen bands lately using 2 810 laid sideways which would be the same physical size as 2 standing up. is that just for transport ease with roadcases?
