Stupid question

[Oldgoat912]

I am the proud owner of a set of Cornwalls which I purchased in the early 1980.  They are still functioning perfectly and in excellent condition.  Type CWO and the serial numbers are 145944 and 145945,

All components remain the same that came out of the box.  LOVE them.  Unfortunately, I don't remember where the paperwork is and after 40 years I don't remember many of the specs.  I would like to know the efficiency rating of my babies.  Can anyone enlighten me?  Thanks.

Welcome, I moved this to 2 ch because the curator of the museum which is the Historian is on a part time schedule because of covid. It will probably be seen faster and get an answer faster here.

You can also check the archives section at Klipsch.com.

Just fyi the 5 is actually an S in the serial numbers, so they're 14S944 and 14S955.

Thank you gentlemen.  Apparently my 50/50 vision did not catch the "S" that I mistook for a 5.  So, my Cornwall II speakers were manufactured in 1978.  They still sound great and were one hell of a lot more affordable then than they are now.

Actually, just Cornwall... then came the Cornwall II, III, and now IV.

 

But they are all good, even with the ever increasing prices.

From that spec sheet posted above: Refers to a Cornwall II. Jim has explained this a couple of times, a lot of confusion about this. There were two "II"? There is spot about it in ask the Historian
