mustang guy Posted September 11, 2014 Share Posted September 11, 2014 What is the horn on these Jubes? Quote Link to comment Share on other sites More sharing options...
PrestonTom Posted September 11, 2014 Share Posted September 11, 2014 Good Question. That is a K-403 horn. It has a 1.4 inch throat and had a very limited prduction run. That was used to produce a few fiberglass version and a few wooden versions (same geometry in both). The wooden versions are nice looking but there were quality control problems. There is no mold or jig for fabricating more of them . The expansion was a "modified tractrix" in the horizontal but not the vertical dimensions. The closest offereing you can get from Klipsch is probably the K-510 horn (others may find that statement highly qualified and arguable). I do not think any of the small shops are making clones of the K-403 (and I would be skeptical of what might get produced). Quote Link to comment Share on other sites More sharing options...
Schu Posted September 11, 2014 Share Posted September 11, 2014 if you can even get a 510 by itself... Quote Link to comment Share on other sites More sharing options...
ClaudeJ1 Posted September 11, 2014 Share Posted September 11, 2014 if you can even get a 510 by itself... I have two of the latest ones with modified corners that were purchased without a driver. You can't do that with a K- 402, though. Quote Link to comment Share on other sites More sharing options...
ClaudeJ1 Posted September 11, 2014 Share Posted September 11, 2014 BTW, that photo of PWK with the Jubilee, I believe, was taken at Caesar's Palace at a CES show in Las Vegas, 1999. Quote Link to comment Share on other sites More sharing options...
Max2 Posted September 11, 2014 Share Posted September 11, 2014 Does anyone know how well PWK "liked" the two way setup? Maybe he had some reservations about it or maybe he thought is was a clear winner over a 3 way? Quote Link to comment Share on other sites More sharing options...
Thaddeus Smith Posted September 11, 2014 Share Posted September 11, 2014 I think I've read anecdotes indicating that the 2-way Jub is the Klipschorn he always wanted from the beginning. 1 Quote Link to comment Share on other sites More sharing options...

The Dude Posted September 11, 2014 Share Posted September 11, 2014 modified tractrix Is that why it has what looks to be curved sides. Other then that it reminds me of the EV Hp640, size wise at least. Quote Link to comment Share on other sites More sharing options...
Max2 Posted September 11, 2014 Share Posted September 11, 2014 (edited) A good link on it here http://www.itishifi.com/search/label/Jubilee More 403 pics. At least I think they're all 403's Edited September 11, 2014 by Max2 Quote Link to comment Share on other sites More sharing options...
Fjd Posted September 11, 2014 Share Posted September 11, 2014 (edited) The pair in this picture may be the Martinelli horns. See post 65 in the linked thread. https://community.klipsch.com/index.php?/topic/141794-the-history-of-the-jubilee/page-4 Note that Martinelli was the builder of ALK's original Trachorn too; however, he retired from horn building after doing a few pairs of 2" throat Trachorns.

Max2 Posted September 11, 2014 Share Posted September 11, 2014 I found this tidbit in the article "This wooden one was made in Italy but they mistook the bumps in the horn for a mistake instead of an intentional transition point in the horn. I can only imagine how mad PWK and Roy were when this showed up at Klipsch labs after shelling out thousands of dollars." Quote Link to comment Share on other sites More sharing options...
seti Posted September 11, 2014 Share Posted September 11, 2014 (edited) I lucked into a Pair of 403's. I put B&C DE82TN drivers on them as they are what PWK picked out. They are great. They feature Roy's modified tractrix and PWK's collapsing verticles. Curves aren't bad either.... Dirty not smoothed....

No. I spent a good deal of time learning about the Jubilee and how to set up a Jubilee system Quote Link to comment Share on other sites More sharing options...

My understanding is that multiple vendors were used, but the results were not up to snuff. Quote Link to comment Share on other sites More sharing options...
PrestonTom Posted September 11, 2014 Share Posted September 11, 2014 modified tractrix Is that why it has what looks to be curved sides. Other then that it reminds me of the EV Hp640, size wise at least. The geometry on the EV HP640 horn is different than the "modified tractrix". I have had both. I will say that the EV HP640 is a very nice horn. They are available on eBay at affordable prices and and would be an excellent candidate for many of the projects that I see on the Klipsch forum.
