I wiped up a testing board for my 1-12" speaker cab. It will allow me to swap speakers in and out quickly by just dropping in a speaker and setting the board over it. I used 2 big hand screws and made some pressed in nuts for the cab so it's easy. I'll put alligator clips on the wires too. This should make it easy to go from speaker to speaker before I forget what one sounds like when testing or comparing them.
