thanks that's what i was thinking but the first character just threw me off. i appreciate the response. do the early ones have any more value? i'm gonna list these for sale. more speakers than i need and i just got them because of the deal i got. you'd all hate me if you knew what i paid

i recently bought the system and the serial number doesn't match up with the charts i've seen. there;s an extra letter/number in front of the k. the serial number is ok225 and ok224. not sure if the first letter/number is an "o" or a "0". any help would be appreciated. my best guess is 1972 because of the k but i haven't seen any other examples of the first character being there.
