I am so glad to see the level of dedication and support that each of you are investing to bring this about. I will be happy to support the effort financially when the non-profit status becomes official. Looking forward to updates as they are posted.

Travis you're right on target. The Jubilee should be included in the discussion of this concept with the development of a complete cosmetic package for this outstanding product. I would like to see a new state-of-the-art hf horn developed which is intermediate sized between the K-510 and the K-402. This could facilitate the development of cosmetic treatments which allow for no- compromise performance and appearance for the Jubilee. Hopefully the R&D costs for a new horn can be borne by future product applications on the professional side. If Klipsch does this, I will be first in line with my wallet open

It's a no brainer. Levi's has a custom shop, 350 to 500 a pair, in San Francisco. The Fender Custom Shop is legendary.
What year are we up to on Paul's birthday this year? Create a Signature Model, Be drivers, etc.
Make that Jubilee bass bin in a real exotic wood, with grill covers, and get Roy to make a wood horn to match size of 502. You do that, set it up in a great listening space at CES, I think you could sell a 100 pair right off the floor at 20K a pair retail.
Get Billy Bob Thorton to design a pair, and sell a limited edition of those, etc., etc.
Made to order, money up front, accurate waiting times given, no inventory to carry. Chad can create an app or way customers can check status, on real time, just like shipping a UPS package?
Who ever asked you to check into this is a genius Chad and I like the way they think.
I was talking about this very thing with some photographer dude just the other day.

Mike,
IIRC, Roy said Paul never got to hear the K-402 but he did hear the K-510. He wanted a larger horn than the K-510 for the Jubilee (home version) and liked horns with collapsing polars. Roy was working with constant- coverage horn designs (K-510). The K-403 was already developed and was a hybrid design which collapses the vertical polars but maintains the horizontal polars. I believe the K-403 was to be the template for the pretty wooden horn in the pictures of the home Jubilee. I can't speak to the question of nomenclature, perhaps the numbering system is based on assignment for production not development. Hopefully, Roy will let us know.
-
Mike, I recall the K-403 as being an R&D piece that was older than the K-510. The K-402 was developed after the K-510.

I used stacked Heresys for a budget center channel setup between Khorns during college. Worked pretty well.

Sold the '99 Grand Cherokee with 238k and replaced it with a '02 Grand Cherokee because the first one was reliable for us. Both were used, low mileage. I still drive the '56 Imperial as a daily driver ( 392 Hemi - FUN CAR ! )

I appreciate the passion and commitment that each of these gentlemen bring to their audio pursuits. Doc nailed it when he referred to the complexity of understanding the variables involved and trying to balance them in a system.
Many of us own heritage systems that are getting to an age where network components need replacement, hence the ongoing discussions, spirited, misguided or devisive as they may be.
I often wish we could come up with a means of ranking each of these networks, perhaps as a result of a big crossover shootout with enough attendees that the opinions expressed would represent a significant crossection of forum contributors. If this ever happens it should include the factory networks for reference. The roadshow approach is great but it clearly has its limitations in terms of what can be learned by someone who didn't participate directly.
This is the 21st century after all. Shouldn't we be able to quantify the meaningful differences between competing systems better than we have so far? Maybe I expect too much from 2015 or maybe we are underperforming in our communication somehow.
What do you think?

Hey Dean,
What happens when your son starts removing parts from that passive and gets down to 0? Hmmm - time to start exploring actives ????
SORRY Dean, I just couldn't! resist!!!!

First, I want to say thanks for responding as you have, it is a refreshing departure from today's politically correct corporate world.
As a long-time owner of Klipsch products, I want to share a few thoughts;
The challenge of marketing the Klipsch brand of products is completely different today than in decades past. The array of products is broad (out of necessity) compared with the Heritage lineup of the 60's and 70's and the independent retail dealer business model is all but non-existent today. The product and marketing segmentation which results from this makes it hard to maintain a coherent brand identity that consumers can relate to as they could in the past. I feel that Klipsch's recent efforts to introduce PWK, company history and product philosophy to a new generation of consumers is a positive step. Now the company must respond by backing that up with ALL of the products and services that reflect that philosophy.
When I was first introduced to Klipsch products more than 40 years ago, there were THREE VERY SPECIFIC THINGS that attracted my attention to the brand;
1. "If you cannot hear the difference, you are not ready for Klipsch speakers yet" ( This achieves what the best marketing messages achieve- it is a call to action because it personalizes the message. You must hear for yourself to see if it is really true!)
2. Superior design and craftmanship over most competitors
3. Dedication to continual product improvement /low obsolescence /ability to update for a lifetime (This is a big deal as it is so rare!)
I have presented these points because I believe that they remain relevant and therefore valuable to the company's success going forward.
Thanks again for your post.

I would like to convert my 3 channel Klipschorn / Belle Klipsch system to a two-way system with the K-510's and build a center channel speaker with the other K-510 for my Jubilee system.
-
The original K-700 horn was sand-cast aluminum, fairly thick walled, used for many years for the Heresy. The replacement was die-cast aluminum, thinner walled than the original but with better dimensional uniformity. It has smoother frequency response than the original.

I would buy 4 510's if available.

Hope that's marine grade plywood-- the sky looks threatening!

Well Marty, they say timing is everything, right? Interesting to ponder!

The type D and type C crossovers maintain the same polarity to all drivers. Only the type E crossover reverses polarity to the midrange and tweeter relative to the woofer.
-
C2 is the only cap change needed, from 2.0uf to 1.0uf. You are correct on the autoformer taps, midrange changes from tap 2 to tap 1, tweeter changes from tap 3 to tap 2. If you look at the schematic of the E network, you will notice the polarity reversal for the midrange and tweeter is done on the 'back' side of the terminal block. it is easier to simply reverse the black and red leads for the midrange and tweeter on the 'front' side of the terminal block to achieve the same result.
-
They are different enough to detect. I wouldn't mix them side-to-side but front-to-back would be acceptable for most listeners here.
(there now... is that better?)
-
There are two threads on type C and type D networks going on in the technical/modifications section right now. If you look at the schematics posted there, you will see how to convert a type E or D network to a type C. Very simple with one change in cap value and changing the midrange and tweeter taps one step lower.
-
Hey JFT,
If you compare the schematic for the type E network posted above with your type D, you will see the only difference is the reversal of polarity on the midrange and tweeter relative to the woofer. The type E provides some cancellation in output centered around 700 hz where the woofer and midrange output overlap. This makes the lower midrange sound less full, less prominant. To hear what that is like, simply reverse the leads on the midrange and tweeter where they attach to the terminal strip.
-
Please remember if you have type E crossovers (factory or aftermarket) both the midrange and tweeter are set to +3db on the autotransformer as compared with the original type C crossover. It will definately sound more forward than it did from the factory. If you want to hear what the H-700's were like when new, you can try the type C setup.

Beautiful Klipschorns, congratulations!
The signature looks authentic to me, almost the same as on my Belle and another personally autographed item from when I met the man.

I would love to hear Roy's description of the development and evaluation process for crossover networks and speaker voicing. When the decision was made to develop the AK-4 to replace the AK-3 it seems to have represented a significant change in how the crossover network is used to balance more attributes of the speaker system performance. In the case of the AK-4 and AL-4 being developed for existing systems, how many people were involved in the evaluation process, what are the discussions like, how closely does everyone agree before crossover voicing specs get locked in?
