Has anyone ever used a E-140 in a sealed cab? I've got one coming along with a Mesa Diesel 1X15(has an EV in it). I was planning on making a cab the same size as the Diesel(to make stacking easy), but sealed for the JBL. How well would that size work? I'm assuming the Diesel would handle the lows while the JBL handles the punch since it'd be higher in the air. I'd be using 4 and 5 string basses although I mainly only go as low as the D note on the B string, but sometimes use the B.
