Driver identity?

[MMBRacing]

Purchased about 18 years ago for a diy project but have lost all the paper work and age has addled the mind. The only markings are two numbers on each driver, "801179" which is common to both and "75144282" and "75142582" which are unique to each. I realize that the chances of identifying are probably slim to nil but I can hope.

Thanks in advance

Well someone else asked a question about this number before, thinking it was a peerless subwoofer:

But based on the response it seems unlikely.
