Hey all. While trying to sell my crate blue voodoo 4x12 cab, which I thought had Celestion vintage 30s, I opened up the back and found 4 unmarked black speakers. All they had were a couple of serial numbers, which I've listed below. Could anyone help shed some light as to what these mystery speakers are? Thanks a lot for the help.
