I have a question. How do you wire a 3-speaker cab to acheive a 4ohm resistance? (Like the epifani ul-310) You can do it by alternating the speaker ohm, but what if you want keep the same speaker ohm? Say, if i want to wire a cab using 3 - 8ohm speakers, how would you go about doing this? I already ordered the cab construction book, but im gonna jump the gun and ask you guys first.
