"D K" Stamp on rear of HWL

[tdonovanj]

Just wondering what the significance of these letters are? In addition to the D and K there is also USA stamped twice and at the top of each back are the serial numbers 144X552 and 144X553.  These are (I think) late 1982 H1s as they do have the E2 XO. Although the number "2" is stamped next to the red E rather than being printed. 

Any insight on the D and K would be appreciated! 

Thanks

@HDBRbuilder can elaborate, but my understanding is they are initials of the cabinet makers. See my discussion in thread 1980 Heresy under Ask the Historian, @JRH

Thanks jcn3 but I already know the code. My question had to do with the stamped D and K in the edge of the back of my speakers.

Those are the initials of either the sander or woodworker that built the pair.  @HDBRbuilder might know to whom those belong.
