ID These JBL Cornerhorns ?

I was emailed these pics by Johm who just purchased them and wants to know exactly what they are..

Here is the email I received..

I just bought these and have no idea what they truly are. I know of 1 other pair that surfaced on the web in 2009. There is a rumor that they were made by Bill Hartsfield as a bet between him and William Thomas of jbl. He  said he could build a speaker that uses a 8" driver that would rival the Hartsfield. Only 12 was made according to the rumor. The drivers are d216,075 and N2400. They both have JBL registry cards with consecutive serial numbers for the drivers. The inside horn path looks just like the hartsfield patent drawing. Any info would be greatly appreciated.


Ok JBL experts what exactly does John have here??

Measurements are 32"h x 19" x 19"

A Corner Labrinth Transducer

This is an interesting critter. It meets my first criteria in a speaker which is that it isn't small but it could be bigger still. I have severe distaste for small speakers. If you want it to sound real make it big. If you want it to sound like a speaker make it small. Ok sorry for the rant there. This looks like a missing link or like a bunch of speakers went to an orgy and this came out as a backloaded cornerhorn karson looking thingy.




Fulmer's patent is here http://www.google.com/patents?id=yh9qAAAAEBAJ&dq=2787332

Early Voigt Horns

Paul Voigt is one of the early audio pioneers and unfortunately often overlooked. He designed corner horns, drivers, tonearms and cartridges. The man was a genius. Until recently it was very difficult to find any historical information about him. I hadn't even heard of him until I saw four of his corner horns and one of his tractrix horns in the Klipsch Factory Museum. He was the second person on record to build corner horns before PWK.

Here are some pics of his early designs.








There are extremely rare. Voigt 30's tractrix horn.




Voigt horns were powered by Lowther drivers. Voigt and Lowther were business partners but if you are interested in the history of these speakers please visit the Lowther Voigt Museum website. This website was long overdue and I was so happy to see it come online.
