Need help with dating Dunlavy SC4's

Dating a speaker sounds rather extreme to me but to each their own. No judgement.

@viridian  Thanks for your much appreciated response.  I'm guessing these are mid to late 90's.  I figured that I would put out the question and perhaps come across an ex-employee or someone that would have had some info to help me nail down the date.

@judsauce, I bought a pair of Duntech Princess in 1990, built in Australia.  It was after that when John Dunlavy returned to the US to open a new facility to build in Utah.  I think that was called the Black Knight.  My assumption he set up production in the US to avoid such long shipping for very heavy speakers.  Mine weighed 180 pounds each.  It was not the success Duntech hoped for and John left the company to open Dunlavy Audio Labs in Co.  I'm not sure of that date but at least a couple of years passed since 1990.

From that I would say the pair reviewed by Stereophile were early so built in 1993 or 4.  What gets interesting is how much higher your serial numbers are, plus the are A/B with the same number rather than sequential numbers. ?

Also after John became ill and sold DAL it did not survive more than a year.  With the different serial sequence could yours have been from that last company?
