is the Klipsch Jubilee some offshoot of the

The folding geometry of the Jubilee is a one plane re-entrant type where the horn expands at the throat horizontally instead of vertically like the old style Klipschorn. I saw the same folding geometry in a later version of the Vitavox corner horn. A customer of mine had one. When I first saw the Vitavox, I assumed that it was their version of the Khorn. But he showed me that it expanded horizontally from one Baker 15" woofer. The Jubilee uses two 12" woofers with two horizontal expanding throat manifolds. I do not know if Roy Delgado had ever seen or heard about the Vitavox horn. But the folding options are limited so a horizontal configuration is a viable choice. I'm trying to rack my brain, but the Hartsfield, I think, is a horizontal folding configuration. Roy would be familiar with the Hartsfield layout. The next time I'm in Hope, I'll try to remember to ask Roy. Bruce

The one you are showing is the later version. It had the first expansion vertically, and then the rest was horizontal. The earlier version of the Hartsfield also had the first sections vertical, and the final one horizontal. The early version was made as an expandable system, whaere you could start with a single 8" driver, back loaded into the horn, and then expand on the system as your budget allowed, The early version can be seen here:

I could remember most of the salient points but was somewhat hazy on the details. BTW on the later Hartsfield drawing, the back chamber looks like it can only accommodate a 12" woofer. I thought they used 15" woofers.

The question was: Is the Jubilee like a Frazier, the answer is NO, it is like a JBL.

In general, Frazier used a stepped construction for his horns, not like the Klipsch or JBL.
