Stamped steel, painted in black hammertone, actually. The cone code (5276?) doesn't ring a bell. From the date code, I'd guess '80 but Fane did some strange things during that era. Could be '83 production, I guessjrsdws wrote:They appear to be cast iron speakers by the pictures.

125155's were introduced for the front-loaded cabs. My front-loader (serial number in the very early 9000's, IIRC) has 122142's. Not sure if the 125155's are closer to a 122231 or a 122142, though. Might be able to tell by relative weight (142's have heavier magnets).
