These are walnut oiled. The pie-shaped logo was used from the early 60's until the early 70's. I don't have a solid confirmation of the latter date.

Cool!!

Not sure of the entire answer, but jpg for me.

If the woofers are visibly OK and functioning, and the caps are not leaking oil, I would leave them alone.

The 15 does stand for a 15" woofer. Early on a few were built with 12" woofers. Without reviewing 100's of pages of records in detail, it appear at first glance that none were done after about 1963. I've never seen one.

To see previous and current transactions, I would recommend monitoring https://community.klipsch.com/index.php?/forum/63-garage-sale/, as well as eBay. We have mid-50's stock Khorns playing in our visitors Center. They always impress, so 1969 should be, at the least, "respectable". Considering that new ones are $18,000, I wouldn't think they should go for less than $2000 each, assuming they are in good condition. But current value is not my forte (pun intended).

4/9/81 shipped to Harvey Group.

I am not aware of any production quantity records of these, nor PWK being heavily involved in the run. Sorry.

Not aware of such. Could possibly be a counterfeit.

397 and 398 shipped 23 Aug 1962. The logbook does not indicate destination. It appears that the drivers are original, or at least "as shipped". The logbook reflects a change in nomenclature from SP12B to K-22 in October of 1960. Likely the same driver with the addition of a Klipsch label. The component price lists also begin to refer to "K-22" in 1960. When the Heresy came out in late 1957, the K-ortho-12 compliment of drivers was in place for some Shorthorns. These were likely brought into Heresy service initially.

35R847 shipped 2/17/77 to Audio International in Germany. The woofer is an "unauthorized" replacement, and the tweeter is a newer "authorized" replacement.

Sorry, but that logbook has been AWOL for years. I have never seen one with two HF's. The HF cabinets may not be stock. Do they both contain the same components?

MEL stands for Macassar Ebony Lacquer.

Serial numbers are too new. Record keeping went south with the advent of computers!

These are 2 of 4 shipped to Spain on 5/20/80. They must have never seen "professional" use, as they look to be pristine!
