Hey All My next project is to build a 4x10 cab to be used with various amps, fenders and a few others. The impedances I need are 2 ohm, 4 ohm, 8 ohm and 16 ohm all mono. I figure this way, I should be able to connect any of my amps to it as I would have the matching impedance available on the cab. But I am hearing that this is not an easy one to achieve. Has this not been done prior? How can it be accomplished?
