Okay so heres the skinny. I just recently broke down and purchased a new Avatar B2x12 Delta and a Ashdown MAg600. Okay so my guitr players are using a Marshall 100wt head and 4x12 cab and the other is a 5152 head 100wt and a Genz-Benz cab 4x12. Now i figured even at the 8ohm level I was going to be able to blow them out of the water. I still can't keep up volume wise even at full output level without clipping the amp! I even put another 4x10 cab with it and still couldn't keep up with the levels. Whats wrong with this picture. I mean is 575wts still not enough. I am going crazy trying to figure this one out. I need help.
