Need help with dating Dunlavy SC4's

Greetings fellow enthusiasts!

I need help in finding the manufacturing date of a pair of Dunlavy SC4's.

Serial numbers are 1231A and 1231B.

I'm not too tech savvy and have not had success in Google searching for dates by serial number.

Any help would be most appreciated.

Thank you!

Do you think if I mated my sc4's with a pair of sc4a's that they would produce a little Athena? @viridian this isn't a debate about sealed or ported enclosures. It's about finding out about a manufacturing date of the above mentioned speakers. If you have any advice on their age, please share. Would welcome your input.Thanks.

He tweaked every speaker in his sound lab in Colorado prior to shipping them. I have the sc 5,sc6 and 2002. They are big heavy and sound great to this day. There are some forums that have heavily modified his speakers. He did first order crossovers and had patterns on the felt around the speakers long live the legacy of that engineer.enjoy the music.
