Upstart555 Posted November 8, 2004 Share Posted November 8, 2004 I am wanting to buy a pair of Klipsch Heresy speakers between the years 1975 and 1980 but I want to know if the date of manufacture is always printed on the back of these speakers. If not could you tell by the serial number? Also if anyone has a good pair of Heresys for sale let me know. Problem is I live in Hawaii. I have put an add in the paper and got a few replies from responders for La scalas and K-horns which I know nothing about. I just heard a friend's Heresys years ago and was smitten. Any help would be greatly appreciated. Mark in Maui Quote Link to comment Share on other sites More sharing options...
Myhamish Posted November 8, 2004 Share Posted November 8, 2004 Hi Mark, Oh I wish I was in Maui right now. It's snowing like crazy here. Anyway, welcome to the forum. Anyway, if you've got the room and $ and there's Klipschorns and/or LaScalas in your area, you might want to check them out. Lots of information available through the search function in the forum here. Anyway, here's the date code info for Klipsch products. Good luck and let us know how you make out. Hamish KLIPSCH S/N FORMATS DATES DESCRIPTION EXAMPLE 1946-1947 ### 001 (ending #021) 1948-1961 #### 0121 (starting #0121) 1962-1983 ##letter#### 20Y1234 1984-1989(?) YY WW #### 89281234 1990-1997(?)

fini Posted November 8, 2004 Share Posted November 8, 2004 You know, sometimes I wonder why they didn't just have a space on the tag for a manufacturing date, written conventionally. It's like you need a decoder ring from a serial box... Quote Link to comment Share on other sites More sharing options...

My guess is the latter... DM Quote Link to comment Share on other sites More sharing options...
Upstart555 Posted November 9, 2004 Author Share Posted November 9, 2004 Hamish, thanks loads for the info. Preciate it. You know this daily sunshine can be quite monotonous. We all would love if it would snow sometimes here in Maui, just as long as it could happen without the temp goin below 70f. Mark Quote Link to comment Share on other sites More sharing options...
