I'm comparing two of the insanely powerful 10 inch speakers that Stevie Ray Vaughan used: Electrovoice EVM10L and JBL E110. These speakers are both rated at 200W so the entire 4x10 is 800W, still they are extremely dynamic also at lower volumes. I'm putting two of each in Blues DeVille 4x10 cab. I'm using a 1971 Marshall JMP Super Lead, a Fender Stratocaster with 1960s Lipstick pickups and a Fryette power station to bring down the volume.
