Another sideways version, evidently they fire backwards

which looks like a cobraflex horn

Would love to hear that. Looks like a hard way to build a speaker.

That first pic looks like a slice from the top of a Tannoy Prestige series horn, something like the Westminster, Canterbury, Autograph, etc.

Ok folks, what you are seeing here is taking catscan technology and bringing it to folded horn design; making "slices", then programming the "slice" dimensions into a CNC machine, which in turn cuts out each slice, then the slices are stacked, and you have your Horn, pretty simple, and was bound to happen sooner or later!

IOW, why hire skilled craftsmen, or train employees to BE skilled craftsmen, when you can simply hire folks to spread glue on MDF slices and stack them up, in order to have your big old horns?? Extreme labor cost savings, savings in overhead for the wood shops, while maximizing profits!

Look at the process of using this technique for the Research and Development end of things! The engineers design the horn using CAD technology, turn it into slices, have the woodshop use CNC to make slices, then stack it all up, test it, make changes, do it again. Another advantage is that by using slices, you can make the outside shape of the overall cabinet pretty much anything you want as long as it retains the horn lens design parameters. This could also relate to making horn lens mouth changes rapidly to eliminate standing wave problems.

Anybody want a K-horn that appears to be a cylinder standing in the corner??

I dunno, but it might behoove Klipsch to rapidly do up a catscan deal on the K-horn, Lascala, etc., figure out the assembly techniques, and try to get a patent on it, if possible, before somebody else steals their wind, unless that wind has already been stolen!

As the ebay ad says, another advantage is that a kit of these horns can be "flat-shipped" for the DIY types, which would likely eliminate the need for a table saw, etc for the home builder. Just LOTS OF CLAMPS!!

Manufacturing by stacking laminates is a VERY powerful technologuy... it's the real reason we won the war (WWII, that is: )

http://www.raytheon.com/technology_today/archive/2002_Issue3.pdf

A good read, if you are into technology, and a good man (Norm Krim, who I know well, featured in the article that describes the Laminated Anode Magnetron.)

From page 12:

"Spencer incorporates several design changes including transitioning from the labor intensive, difficult to rework machining process to a stacked laminate batch process. Piece parts are stamped, called laminations, then silver plated. The laminations are then stacked on top one another in a jig fixure. The stack is then run through a hydrogen furnace which creates a solid core and makes application to magnetrons workable."

“Everybody in the government and at MIT thought that the magnetron would be the bottleneck in microwave radar production. But after Raytheon got going, there was never a shortage of tubes again. We started by turning out one tube every other day and by the end of the war we were turning out 2600 a day,” says Krim.

Just thinking of some other possibilities, this comes to mind:

When using flat panels to assemble up a standard build for something like the LaScala, K-horn, Jubilee, etc...there are certain design characteristics for production versions which must be adopted in order to keep down costs, such as the lack of smooth curvature transitions from one section of the horn lens to another section, which often dictates sharp bends be utilized. Using stacked laminate technology would allow for "smoothing out" those sharp bends somewhat, which MAY actualy make crossover designs and drivers used a much simpler process. IOW it MAY actually be able to cut costs in other areas while improving the final product performance! How about a tractrix K-horn bass bin, for example?? Would that be possible?? I kinda think: maybe so!

I wonder what Roy's take on this is??

It will take a lot more sheets of material to build, with a tremendous amount of waste material. It's still a cool idea, though.
