Very interesting story from the OP. Goes to show us how easy it is to make a mistake and live with it thinking all is fine until up close examination.
These were great sounding speakers for the price. I bought mine in the very early seventies. Found one in a stereo shop marked down. It had white grill cloth and the salesguy offered me a good price for another but with a black grill cloth. Took ‘em. Bought another pair for a quad setup and enjoyed lots of music.
Still have them somewhere in my basement. The veneer is a bit warped from a water leak but otherwise they are untouched since new.
