Original 1960s Klipschorn Corner Horn Speaker

If the network is any indication, this speaker is a University/DIY product/kit.

 

 

At first a quick scan of the pictures I was thinking an EV "kit" build (many brands sold the speakers as kits in the 1950s and 1960s) of the Aristocrat or Baronet.  However, the crossover sure looks like the University and I agree with you that it is most likely a University kit speaker build or a DIY build from just a set of plans.  You never know what drivers will be in a cabinet so it pays to inspect.  It seems that University drivers were used as OEM drivers by other speaker builders too. Not that it is worth much to me, if it is a three-way speaker, even if not a kit and built from a set o plans, that cabinet may have University drivers too and if not, I've seen a couple of these DIY-looking speakers with a 15" Alnico magnet Jensen woofer, an Alnico 8" mid-driver, and the old Calrad tweeter.

 

For those that may not be familiar, here are a few close ups of the University N-3 crossover; along with pictures of the speaker pulled from the advertisement link.

That Jensen woofer has P15P stamped in ink on the basket perimeter. Interesting to note that the first Cornwalls used P15LL Jensen woofers and they are somewhat prized. That tweeter horn looks pretty interesting also. 

 

For a mere $850, and a friend with a dolly, you can buy this gem and bring it home.

The Jensen P15LL (P = Alnico magnet) is really nice and more of a bass woofer and, in addition to those early Cornwalls, can also be found in the Jensen Imperial, the bass woofer in various Leslie organ speaker cabinets, in addition to the “legendary and mythical” Western Electric 753C broadcast/monitor loudspeaker. 

 

Although, many of the Western Electric 753A through the 753C series speakers had a “rebranded” Jensen called the Western Electric KS 12004.  I believe that in early versions the 753 model was a rebranded Jensen A15PM (predecessor to the P15LL).

 

The Jensen P15LL is one of the really desirable woofers for the Leslie speaker cabinet and has a double roll suspension, while models such as the P15Q and some P15N's are single roll suspension and both are more in the full range driver classification.  The P15N and the P12N both tend to be really desirable to guitar players.

 

Given there were so many made, the Jensen P15LL seems to be rather common and I see them selling on eBay for about $75 - $150 each; however, in many instances the cones look pretty worn out and tend to need re-coned.

 

Even the old field coil Jensen F15LL and F12N are fairly common.  I have two of the F12N field coil drivers that I plan to install in a pair of Heresy cabinets that I saved from destruction (someone sold the guts and tossed the cabinets).

 

However,  the Western Electric parts just keep rising in price as just this past September 2015, one of the eBay tube sellers sold a single new in box Western Electric 713C compression driver for $12,966.
