Thanks guys. I have in my possession a pair of heresy speakers. From reading before asking I think I figured out thst they are circa 1974 or 5. They are HDB - 12's (Heresy Decorator 12" woofer, right?). Both inspected by Lester Boyd and tested by WM Bradford. Serial #'s are 10M723 & 10M724. They are flat black with heavy duty grills only over the woofers. They have metal "L brackets" on the corners which do not appear to be stock to my eye. The cabinets are beat up a bit but holy smokes do they ROCK.
Questions are - what did I get right or wrong, what else is there to be learned from the labels, and how much are they worth to a Klipsch?
Also, I love to tell noobs about stuff I'm "expert" on (mountain bikes) so if you want to blast me with cool Klipsch anecdotes, trivia, and history, please have at it. Tell me why these things spoke to me when I saw them all alone and dejected...
