If I bought the epfani 310T how would I reach 5.3 ohms? What I am saying is that if I had an amp that is rated for 4 and 8 ohm operation, would it be safe to hook this cabinet up to it? That is my confustion. I don't know if it is safe to run inbetween marked resistance, I know you can only go so low in ohms before you kill your amp but what about inbetween the marked settings? Also How do you know how many watts it would produce at 5.3 ohms? ohms law?
