Serial number puzzler

[Cason]

Hello all.  I’m a new member here.

I have a pair or Heresy II speakers; oiled walnut, slanted factory risers, brown woven fabric grills, consecutive serial numbers, paper labels on the rear.  I have attempted to establish a manufacture date using several of the online instructions for deciphering Klipsch serial numbers and come up with nothing that makes sense to me.  So, I’m looking for some help here.  The serial numbers are 12644 and 12645.  P/N 09000341122.

 

Inspected by Katy McC, tested by Kevin Morehead.

on one, woofer is k-24 s/n 9046; mid-horn is k-53 s/n 9044; tweeter is k-76 s/n ?004.  I have not pulled the drivers on the other speaker.

Any help establishing the manufacturing date would be most appreciated.  

Thank you

Bob

Have you tried using this:

Yes, I have used that.  Driver codes give a 1990 manufacturing date, but it doesn’t give anything that makes sense for the serial numbers on the label.

I think that's all you are gonna get.  There might be week or day codes, or maybe lot numbers or the like, but Klipsch hasn't given us more.

When Klipsch started using computers, everything serial number-wise went to "something" in a handbasket.
