Billy joe Posted November 7, 2008 Share Posted November 7, 2008 Just trying to figure out what year my lsi's were made. The serial numbers on the back are 1296 and 1297, my friend bought them new in 1978, but was that the year they were made? Quote Link to comment Share on other sites More sharing options...

colterphoto1 Posted November 7, 2008 Share Posted November 7, 2008 There is no way of knowing on the pro gear. That data does not exist and the date codes do not follow the same format as for Heritage gear. Further complicating things, for some years in the 80's another company in Hope actually did the manufacturing. Then Pro went back to Klipsch. They started in the 70's and some pro gear was still being made around 2000. Let me dig some price lists for the LSI. That will at least give a range. A- The LSI is still listed in a 1999 price brochure so was still made until then. I think they started manufacturing around 1976. I worked for a PA company in 1978 and they had the LSI splits and MCM stacks that were fairly new on the market at that time. I have located an engineering letter in my archives that gives the dimensions to add handles to standard LaScala so as to make it 'industrial', this is dated 1977. Sadly, Klipsch is letting go of some of the employees that have personal knowledge of this equipment from this era. History may soon be lost forever.

I don't know of any company who is not either laying folks of or doing hiring/wage freeze. Quote Link to comment Share on other sites More sharing options...
