Klipschorn Jubilee by Roy Delgado and PWK

 The weekend in Hope was a blast. PWK and Roy Delgado's Jubilee two way loudspeaker is truly state of the art. It is simply the best loudspeaker I have ever heard. Roy has it so dialed in it is just amazing. If you can make the pilgrimage in Hope next year please do.  That experience is so fresh in my mind I thought I'd do a Jubilee post.

Roy and PWK started this project in the 90's while PWK was in his 90's. Back then the Jubilee had a K403 which I happen to own as the HF horn. Sadly with Paul's passing the project did not move forward. 


Roy made a great move and had the Jubilee bass bin placed in the pro cinema line. This was a great move as it was in production in some form. Roy saw lot of rapid Klipsch fans on the forums(including me) wanting to know why it wasn't released. Roy Delgado hoping to deter fans pointed them at the cinema line thinking it was way too ugly to put in a home but in a surprising move many fans bought them and put thesed giant cinema speakers in their homes. It is like Henry Ford said you can have it in any color as long as it is black. Personally I love the Klipsch pro line and there are some real gems there. The pro horns and horn loaded subs are top notch.


The hardcore Klipsch fans with these cinema speakers worked very hard to make them fit into their homes. This reminds me of the Klipsch designer speakers where it was up to the decorator or owner to make them look nice. Here are the many early Jubilee's.. This is only available via cinema line so you need a cinema dealer to sell you the setup. 

Here are a few examples of what people of done with their Jubilee's. They start as just black and eventually Klipsch was nice enough to offer a veneered front. So some veneer is factory but most was done by the owner. Check it out.

Klipschorn Jubilee

I edited this from the photo Klipsch released years ago for the CES show. PWK with his last speaker design the Klipschorn Jubilee. It took about 50 years but PWK and Roy Delgado finally bested the Khorn. 

The criteria for his new speaker was:
Smoother response in the passband.
Distortion lower than the Khorn. 
Decrease in second and third harmonic distortion
 Extended LF response past 600hz and it hits about 1500hz.
Bass response lower than the Khorn.
All design goals met.

The 403 Horn by PWK and Roy Delgado

I don't often post on my own equipment. This is mostly because my system is modest by comparison to most of my friends systems. I'll start with one item that is worth sharing which is the 403. This horn was to be the consumer horn for PWK's Jubilee system designed with Roy Delgado. Roy and PWK both had their preferences for horn design. This horn is a combination of their design criteria. From what I have been able to put together Roy uses his trademark modified Tractrix curve and PWK insist on a 1.4 inch throat and collapsing verticals. This creates a great sounding horn with little or no need for eq.. I don't eq this one from 600hz to 18khz.
 28 inches wide
10 inches high
11 inches deep
The 403 horn is a prototype that never went into full production. 
Would I love to have it made out of wood? YES!
Wood was to be the material it was made of but hey it is a miracle I have these horns anyway.

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.

There may be better drivers than the BC DE82 but that is the driver PWK picked out for this horn and for that reason it stays. The only thing I would change would be to roll off the high end a little just before it breaks up on the high end.. I haven't bothered because that is where my hearing drops as well.

This curve is not smoothed just a ballpark one I made of the 403.
 The Jubilee LF and 403 HF were the last horns PWK was involved with at Klipsch and what a way to go out. Horn building and designing to the end.
Thank you Roy and PWK.
