Hi all,
This is crossover for Klipsch horn speakers.
In order to improve the speakers I am thinking about this crossover.
Who knows about this guy WERNER JAGUSCH that built it.
Any information is well respected.
Best regards,
Williams

do your K-horns have stock drivers and crossover? if so, then I'd imagine its a subjective judgement as to the improvement wrought by an improved quality autoformer.
There's not a whole lot wrong with the stock autoformer or ones built for Bob Crites within the range they are used. That autoformer in the Heritage series was used from Heresy to Cornwall to La Scala to Klipschorn.
IMO K-horn bass is quite muddy and don't think the woofer inductor matters a whole lot. My K-horns sound pretty bad whether stock inductor, or a custom inductor by Electra-Print. Part of my problem is resonance from room walls.
Use of vintage oil caps seems good and they can sometimes be sourced cheap (MBGO) enough to try charge coupling by doubling the size of each capacitor and using twice as many caps.
there's a shunt (I think) potentiometer in his setup to vary level and cutoff frequency
Bob Crites has an autoformer which offers 1dB steps.
you can ask the Klipsch community, Audioasylum High Efficiency forum and probably Diyaudio's multi-way forum as this thread may get moved to that section.

here's my right K-horn with microphone in a standing listening position plus mic on the floor and in the basshorn's mouth
I think my problem stems largely from bad room walls and its an energy storage problem more than one of response
that green trace with mic in the center of the midhorn plane is really good - but doesn't sound very good imo.
I have a tiny Karlson Twelve with Kappa12a topped with a K-tube which has more "grab" than my K-horn - but the K-horn
has more midrange "presence" with its tiny but classic K400 horn and K55V phenolic diaphragm driver.
I think I took these traces with a Klipsch network setup to be "Type A" but I have MBGO caps and battery bias. Those old caps
measure acceptably for ESR and may be better in that regard than KBG caps

Hi, I know this guy. I once drove to Oldenburg to pick up those large Jabo horns.
The Jabo's I sold but the autotransformers I kept.
Much better than stock Klipsch.
I just performed a comparison with an L-pad on this wonderful CD: Cipriano de Rore, Ancor Che Col Partire. Outhere music RIC355
In short it sounds way more pleasant with the transformer.
Those brown capacitors are Russian paper in oils. The K40-y are even better but not available in the large values needed.
Edit: the potmeter is used By Werner to controll the roll-off. I do not use that.

losses are probably lower for the deluxe autoformer. Did you use a "swamping resistor" on the Klipsch autoformer when comparing? What is your speaker setup? (Onken?)
In my first apartment I had proper (concrete) corners (walls, ceiling and floor) in the second one the backwall was plaster probably 1/2 " thick. I lost something like 8 dB below 100 Hz or so.
Questions
Yes, I use 10-Ohm resistor on the transformer. Does not make much difference though.
I now am using Heyder horns with Electrovoice 1823M drivers. Tweeters are JBL2404.
So only thing Klipsch left are the bass horns. 😉
