Well maybe it was the student model then.well one has to pay attention because ST is a Student model, the EX ( extra?) was better than that and the SX was the top
Haven't seen the EX series in a while, but I think the EX II series used to be made from German components, but assembled in another country (Czech Republic ? maybe, can't remember). The EX III series may be made in Asia now. They are not the same horn as the SX.So what are the differences in the EX and the SX?
I believe the only difference is that the SX and the EX is that the SX has adjustable palm keys and rolled tone holes. Maybe a tech can chime in with any other info.Well maybe it was the student model then.
So what are the differences in the EX and the SX?
As I recall there were physical differences in the two horns I played.
The lesser horn had different (bouncier) action and did not have the special G# key
Alright. I tracked down photos of all the Keilwerth SX EX and ST different series and compared everything about them such as the body tubes, the keys etc etc.
The conclusion I came to was that something was not quite right about the Amati and Keilwerth connection from what I have read.
The ST-90 Series II and Series III has the same basic tube shape and key shapes and other things as the EX-90 Series II and Series III and the SX-90.
But the ST-90 Series II and Series III and the EX90 series III are supposed to have been made by Amati from what I have read.
Something doesn't add up here but I think I know what happened.
The ST-90 Series II and Series III and the EX90 series III are made from Keilwerth parts manufactured in Germany and then transported to Amati for assembly and finishing.
So Keilwerth gets the assembly and finishing done at a lower price and can then sell them at a lower price.
So over time Keilwerth moved the assembly and finishing for the ST-90 and then the EX-90 to Amati and then finally subcontracted KHS/Jupiter to make the ST-90 Series IV.
The ST-90 Series IV is made by KHS Jupiter in Taiwan ROC.
Saxmaniax.com has this to say:
Model Made in
EX90 Germany
EX90 II Germany
EX90 III Czech Republic
ST 90 I Germany
ST 90 II and III Czech Republic
ST 90 IV Taiwan (Jupiter)
So the list above from Saxmaniax.com is what I also came up with by using photos of the different models and it seems to be pretty accurate except it seems to be this
Model Made in
EX90 Germany
EX90 II Germany
EX90 III Parts made in Germany. Assembly and finishing by Amati in Czech Republic
ST 90 I Germany
ST 90 II and III Parts made in Germany. Assembly and finishing by Amati in Czech Republic
ST 90 IV Taiwan (Jupiter)
All modern Keilwerth sax parts are currently made in Markneukirchen Germany http://en.wikipedia.org/wiki/Markneukirchen except for the ST90 series IV which is made by KHS/Jupiter.
All Amati saxes are done at Kraslice http://en.wikipedia.org/wiki/Kraslice in the Czech Republic.
Kraslice and Markneukirchen are just up the road from each other so to speak.
Originally, the ST90 series I and EX90 series I and II and the SX90 were totally made in Keilwerths Nauheim factory http://en.wikipedia.org/wiki/Nauheim
For the ST90 series II and III (before the opening of Keilwerths Markneukirchen Germany factory in 2001), Keilwerth shipped the parts from Keilwerths Nauheim factory to Amati at Kraslice for assembly and finishing.
Keilwerths Markneukirchen Germany factory opened in 2001 and for a time it appears that there were some parts coming from both the Keilwerths Nauheim factory and the Keilwerths Markneukirchen factory for the SX-90 and EX-90 series III and the EX-90 series III parts were then shipped to Amati at Kraslice for assembly and finishing.
From 2006, Keilwerths Nauheim factory is mainly just used for administration and Keilwerths Markneukirchen factory produces the SX-90 and the EX-90 series III parts which are shipped to Amati at Kraslice for assembly and finishing.
The ST-90 series II appears around 1992 and the ST-90 series III appears around 1995 and the ST-90 series IV then goes to KHS/Jupiter sometime around the late 90s/early 2000s.
The EX-90 series II appears around 1996? and the EX-90 series III appears around early 2000s.
The ST-90 series II and III and the EX-90 series III are made from Keilwerth parts and assembled and finished by Amati and have Amati serial numbers.
I had my Keilwerth ST90 series III serial number verified for the year of manufacture from Amati and the Amati chart below is pretty accurate.
Here are Amati serial numbers that often start with a 3

Keilwerth Factory Tour showing a EX-90 series II being made at approx movie time 12:07 at the now defunct Nauheim factory in Germany.
It also shows a saxophone low B key with a distinctive curved lever attachment at the Nauheim factory in Germany at approx movie time 11.06 - 11:16. The low B key with a distinctive curved lever attachment is a feature of the ST-90 series III which comes from around the same years as the EX-90 series II, thereby basically proving that the ST-90 series II and III and EX-90 series III parts were/are made by Keilwerth.

You are confusing the SX90 and SX90R and EX series.I believe the only difference is that the SX and the EX is that the SX has adjustable palm keys and rolled tone holes. Maybe a tech can chime in with any other info.
Never played any ST except the bari, and it was a terrible horn. At least that example was.This doesn't mean that the ST was a bad horn but it means that the EX and the SX were better made horns but different, exactly like a Yamaha 21 was not like a 61 although they looked pretty similar.
Neck is from keilwerth sx 90r. Sax is equivalent keilwerth ex 90 but i still dont know in which factory was producet.really following my instructions to make the pictures visible here is not difficult.
If you would have done that one would avoid visiting an external site and see it directly. like this...

I am not familiar with this model.
The neck appears to be silver color but is it solid silver?
Strange.

This one looks very much like "Edition" model which is pretty rare Taiwan-made student model (a bit above ST90 S3/4). If that's the case it should have "Edition" on the horn and the case, otherwise you can identify it by the serial number starting with "KE00xxx"really following my instructions to make the pictures visible here is not difficult.

Tipos,
Envié el siguiente correo electrónico a JK:
Tengo un saxo alto Julius keilwerth ST90 Serial # 050511 ROC pero desconozco su serie (I, II, III o IV). Por favor, ¿podría decirme cuál es su serie y dónde se hizo (Alemania, etc...)?
Y obtuve esta respuesta:
Gracias por su correo electrónico y su interés en nuestros instrumentos. Revisé nuestros registros por ti. Los instrumentos St90 con este tipo de números de serie se fabricaron entre 1973 y 1981. Si tu instrumento es un saxofón ST90 data de esta época y fue de la primera serie (I o II). Me preguntaba sobre el ROC escrito en su trompeta porque en ese momento todos los saxofones ST90 provenían de la República Checa y no de China. Por eso no estoy seguro de si se trata de un instrumento de Keilwerth.
Entonces, envié otro correo electrónico con dos fotos, una del grabado JK y otra del número de serie. Estoy esperando la segunda respuesta y la publicaré aquí para quienes quieran saber.
Nos vemos
[/CITA]
Hola,
Y obtuviste alguna respuesta.?
Tengo un tenor ST-90, ROC, serials no concuerda
Reposting my comments of over 10 years ago.I'll just chime in that back in 1998, I went into my local horn dealer about every week. I played most of the top horns of the day and the Kielwerth had the biggest sound by far. Not at all warm like a Selmer but really big without being too bright like the Yanigasawa. I remember thinking "Why isn't the EX the same"? It looked very similar but it just didn't have the big sound. I don't know why? I was using a metal v16 #9 mouthpiece that could really push a horn. Perhaps somebody with a different setup wouldn't notice.?
INMO The horn is not for everybody. If you want a warm Selmer sound I wouldn't get a Kielwerth.
