dougdrake Posted February 11, 2003 Share Posted February 11, 2003 mobile homeless graciously posted this to a web site, as well. I've lost the link. Anyone have it?

Klipsch Employees Trey Cannon Posted February 11, 2003 Klipsch Employees Share Posted February 11, 2003 Doug, That looks like something I did a few years back... FYI: from about 83' to 89'-92 that format may not hold true. 1 Quote Link to comment Share on other sites More sharing options...
dougdrake Posted February 11, 2003 Share Posted February 11, 2003 Trey - I should have given complete credit where due. mobile homeless put up a web page using the data as copied from a document that you created some time ago, and posted to the forum! Sorry 'bout that, Trey. Doug Quote Link to comment Share on other sites More sharing options...

Klipsch Employees Trey Cannon Posted February 15, 2003 Klipsch Employees Share Posted February 15, 2003 Well its a bit vague, but from what I know the format and SN data was placed on computer around that time. Dont laugh, but they were using the old trash 80 and 8inch floppy disk. Remembering that we are a speaker co and how a floppy stores data you can put 2 and 2 togetherthe result is that we dont have that info any longer. Every company makes mistakes from time to time, that was one of ours. 1 Quote Link to comment Share on other sites More sharing options...
markw Posted February 15, 2003 Share Posted February 15, 2003 Trey, Does this hold true for the "Cornwall II's" (first version) I could swear they were '69 (the QC labels were ruined in a fire) but your info puts the date at '72. Thanks. Quote Link to comment Share on other sites More sharing options...
Klipsch Employees Trey Cannon Posted February 16, 2003 Klipsch Employees Share Posted February 16, 2003 The II in the name of your speaker that has the letter K in the SN tells me that they may be of another style than the standard Cornwall. My 1967 models have the II in the name, and they have vertical mounted horns If you will send me an email at work I will try and look your speakers up in the old logbooks. That may give us a bit more info. My best guess is that they are 1969. 1 Quote Link to comment Share on other sites More sharing options...

HDBRbuilder Posted February 20, 2003 Share Posted February 20, 2003 Serial numbers using the letter codes to denote the year of manufacture as given by Trey are correct. For obvious reasons the letter "Z" was not used (looks too much like a "2" when hand-written on the labels), and for the same reason the letter "V" was deleted, (since when hand-written it could easily be interpreted as EITHER a "U" or a "V"), this reasoning also underlies the deletion of the letters "O" and "Q"(since they could be easily misread as a zero...OR each other, when hand-written on labels). I was working there when the decision to delete the letter "V" was made...but that decision came a bit late...since a number of speakers had already left the plant with a "V" on the label! So...if you ever see or read about one of the speakers having a "V" in its serial number...just believe it...because there are a few hundred of them (mostly Heresys, of course)produced in January of 1981 out there! LOL! And speaking of 1981...around late February of that year...all the final assembly people were called together to get a good "reaming" over the fact that SOME of the speakers had "W" letters on them that looked more like a "U"...and they were told to slow down when writing out the serial numbers on the labels and make sure their "W" LOOKED LIKE A "W"...LOL! Needless to say...we all heard about this at break time from the final assembly folks...most of whom said "How the hell can we slow down to do this 'W' the way they want it, and still get out what they expect us to get out the door each day?" Go figure! Another interesting side-note: SOME of the speakers produced and shipped at the very end of November, 1977 ended up being labelled with an "S" in their serial number (again, Heresys...primarily decorator models), because there were only three digits allowable following the letter at the time, and so many were shipped that month, that it required those newbie employees in final assembly who wrote out the labels to go to the next letter to compensate for this. This oversite was corrected AFTER these had been shipped...and it was determined that it was "no big deal" as long as it didn't happen again...since it didn't involve many speakers to begin with. Basically...what I am saying here is that there are instances of these codes not holding entirely true in determining the actual year of manufacture...but they are GENERALLY and FOR THE MOST PART true!

Sounds like a episode of Law & Order where some speakers got placed on a evidence box with tapes of a murder testimony. Be glad payroll wasn't on the disc Quote Link to comment Share on other sites More sharing options...
