I covered this area in an earlier post, which you can find here. There is an inferred set of plans online, which has been traced and reconstructed from the original patent. This is a fairly rough cabinet though and not livingroom friendly. They will deliver the PA edition to private buyers. The Jubilee is mostly found in DIY versions, since Klipsch is not selling a consumer edition. Suffice to say it has equal or lower bass response and a significantly higher cutoff. Under Related Material below, you can find the patent of the Jubilee, explaining the design considerations and strategy, I won't go into great detail here. PWK was apparently unsatisfied with this and as his final act of speakerdevelopment designed the Jubilee, together with Roy Delgado.

PWK started the Khorn as a 2-way, but with increasing bandwidth of source material, stretching the midrange driver more into treble territory was unfeasible and the Khorn evolved into a 3-way loudspeaker. The Jubilee is either an update, or a replacement to the old familiar Klipschorn, it depends a bit on your perspective. In any case, the plans I found are recently inferred from an actual specimen, by a Klisch forums member. I think it was in the Dope from Hope series. I don't know where that filter schematic is, it would be nice to add it here. There was a filternetwork to go with it, which summed/detracted the left and right channels and filtered out the center channel information out of it. At the time it was intended to fill a sonic gap, if the two Klipschorns were placed too far apart. The Belle was designed as a third, center speaker, to go between two Klipsch horns. There are some differences to be found, but these are fairly minimal and uncritical. Horn/expansionwise, it should be more or less the same. It is the same height, less deep but wider.
I think they measured dimensions that they could reach, and deduced the others.īasically, the Belle is a LaScala in different aspect ratios. This has been reconstructed from measurements on real life LaScala's. The other is a later reconstruction by a member of the Klipsch forum.
Folded horn speaker design update#
It was originally in metric and published in Germany, there is also an update in inches available here. It turned out to work well inside the home as well and was taken into production by Klipsch.
Interestingly enough, the LaScala started out as a PA-speaker, supposedly used to fire speeches off a campaign-truck in an election.

Due to the massive amount of plans and the apparently limited amount of differences, I list two: a full version and only the bass section. The plans available online are often tied to a 1949 version of the Khorn. They are all basically the same, although there seems to be a preference for older versions. Obviously, with its long lifespan and many occasions of publication, there are bound to be many versions out there. It is one of the most copied and home-built horns around. Other all-horn systems by PWK were conceived to offer Klipschorn technology in smaller or less placement-dependend packages (LaScala/Belle) or technological refinements (Jubilee). The Klipschorn is the big one, the design that PWK first released and that formed the Klipsch reputation. There are differences (panel thickness for instance) and they might matter in your situation. If you are serious about making an elaborate Klipsch design, you should really take some time to research the various available versions.
Note that various versions of each model are in circulation, as are various derived designs. I see there are a lot of people looking for construction drawings of all the vintage Klipsch horn systems.
