This may be a silly question but do two 4x10 cabs give you the same SPL, tone or the Mojo of an 8x10? I have looked up the specs of say an Ashdown 4x10 = 103db and their 8x10 = 109db. Also people say that as a quad box has the 2 of its drivers stacked vertically it has bad dispersal yet an 8x10 can fill a room/stadium. I would love to hear the maths and since of the two options and from anybody who has had personal experience with the two set ups. I am also considering two 6x10 cabs and a ladder.
