I'm just curious to see if anyone's built a 3x10, specifically along the lines of the old EA cab where they were stacked on top of eachother. 3x10 tower someone called it. Could you use 2 10s tuned low (not really low, that's what my 18 is for ), and then have the third (different speaker, voiced higher) in a seperate chamber angled, like a 4x12 guitar cab? Maybe even 2x10's in one section of the cab and an 8 in the top... Anyone?
