Recommended Posts

Good morning. I was able to pick up some very nice Klipsch Cornwalls. Can you tell me what year they were manufactured and any additional information about the speakers please. 
 

The serial numbers are:

 

8446545 and 8446546

 

Thanks Anthony

There is a decoder ring in another forum (2 channel?), but I'm pretty sure those were made in 1984.

CORNWALL:

  • Oct 1959: The Cornwall is introduced as the world's second commercially produced center speaker. A speaker with higher output capability than the Heresy was needed when used in three speaker arrays between Klipschorn’s. Component designations: Woofer EV 15WK, Midrange K-1000 Horn and University SAHF Driver, Tweeter K-77
  • Late 1959: Transition to the K-33-J Woofer (Jensen)
  • 1959 - 1961: Sporadic transition to the K-55-V mid-range driver (Atlas)
  • Jan 1963: The K-1000 diffraction type midrange horn was replaced with the exponential K-600 horn with a lower (600 Hz) cutoff.
  • Sept 1967: Transition to the K-33-M. The records are not clear as to the origin of this driver but it is believed to be an Eminence driver with an Alnico magnet.
  • Jan 1968: Transition to The K-33-P Woofer (CTS Paducah KY)
  • 1974: The horizontal version of the Cornwall is discontinued
  • 1974: K-56 mid-range driver (Electrovoice 1828) is used for a short period as a temporary replacement as the supply of K-55-V drivers was interrupted.
  • 1975: Transition to The K-33-B Woofer (CTS Brownsville TX)
  • 1975-1979: K-33-E and the K-33-B were used interchangeably.
  • 1979: The Eminence K-33-E woofer is used exclusively
  • June 1981: The updated B2 network, with steeper crossover slopes is phased in with no changes to the K-33-E, K-55-V and K-77-M drivers.
  • Oct 1981 - March 1983: The transition between four different iterations of the midrange driver from revolving sources occurs during this period. The original K-55-V was changed to a K-51-V (10/19/81) This marked the first time in the Cornwall's history that it used a driver set that differed from that of the Klipschorn. The K-51-V was then changed to the K-55-G (essentially a ceramic magnet version of the Atlas Alnico K-55-V). The K-55-G was then changed to the Hepner built K-52-H and finally the Klipsch built K-52-K.
  • Mar 1983: The B-3 network and the K-52 midrange driver starts to be used in this model.  Component designations were: Woofer Eminence K-33-E, Midrange K-57-K (K-600 Aluminum horn and K-52-K driver with the threaded snout), Tweeter K-77-M and B-3 network.

Correct --the klipsch serial numbers codification charged , starting in 1984 -----for the serial numbers 8446545 and 8446546 -84  is the year -------44 could be the  44th week of the year 1984 ---------so these would be  production speakers made on the  last week of  October 1984 --

Thanks for the information. By the way I’ve owned almost every type of high end (Martin Logan, Quad, Magnepan, Meridian and vintage JBLs) speakers these are great sounding.  The Cornwalls, RP8000F and RP600M are my first Klipsch speakers and they are much better than I expected.
