You should to see if there is a Europe supplier, there must be. Have a look on the internet.
Good luck

Just checked in to say that Parts Express, which frequently sells discount, is now selling the Raven tweeters. The R1, R2, and R3 are about $200, $300, and $1,600 respectively.
I have not the slightest idea of the costs involved in shipping to Germany. I just thought that I would inform you of your options.

Just for the record, I did not design ESS electronics.
Initially these were Peter Werback's (later of Linear
Power) and after that they were Bob Byrd (later of
AB Systems).
I just did speakers... 🙂

That's right now I remember from the Harmon Kardon Citation 12 mod in TAA 2/81. Mr.Pass mentioned in that article he worked at ESS. But he didn't design electronics. Could Mr.Pass originally start out as a speaker designer first?

An alternative to Ravens is ESg tweeters. They are not only more sensitive but are the only metal ribbons that are shielded and can be used next to a CRT. I plan on using one in a 100dB/W DIY center channel speaker. According to the importer they are comparable to Ravens, perhaps even better.

Here is a cross-forum thread on the subject.
I heard (and took the pictures) of the AMT-1 conversion that Chris B did. The tweeters are nice.

amt-1
i talked to essspeakers.com and found the price of amt-1d to be 180.00 ea. including the ribbon.
im thinking of building a surround system with these things.
what i need to know is what mid spkr would work best and what type fo x-over would be needed.
thanx all

Re: amt-1
Very reasonable
After Chris finished with his AMT project, he figured he would have been further ahead if he had used the Audax PR17 (paper version).
As to other possibilities, you should be probably looking at the 6" pro mids that are available -- i know eSpeakers has a nice PHL. An alternative might be a pair of the fairly high effeciency Focals.

Re: amt-1
I'll ask Chris for a map of the XO he used for his AMT project. That would give you some good ideas and at least the HP on the AMT would be useful.
And do have a read thru the Decware thread i posted earlier, lots of good info there.

air motin transformers
A little of topic, but I noticed elac (www.elac.com ?) has a heil air motion transformer too called their JET tweeters. Much smaller and circular--don't knowhow deep it goes or if they sell it standalone or what. It seems like the Germans as a whole are doing alot of "high-tech" stuff, even more so than the american scene. I don't know everything out there so it may be a biased view: but they've got the bending wave transducers, the only speaker company I know if with a plasma tweeter in production, heil air motion transformers, etc. None of which necessarily means higher-fidelity, but...

amt-1
thanx for the info.
ive been thinking of building an amt-1 surround system for some time and now i guess im about ready to do it. I'll use my hsu sub with it.
should be cheap enough to build , and sound pretty good.

After a long time I am back to these posts here.
I got a pair of AMT´s to make some speakers.
I was supposed to use them in a 2 way system with 2 focal 8V4411 woofers per box. I can´t find these anymore, so I was thinking about a new design idea.
If you have any ideas for a 2 way system with amts please share here.
I am looking for a bassbox that goes up to 1800Hz at 95 dB.

Hi Promitheus
In the current issue of the German magazine "Hobby HiFi" you will find a project using the AMT.
It is using 3 Seas 17 cm drivers (OEM versions) in a step-response and frequency-response optimized 2.5 way setup.

Hi Promitheus
I forgot to mentio that this speaker's effieciency is only 90dB and it's impedance is only 2.7.Ohms.

Yeah I have this magazine. It is a very interesting design but too complicated for me. I want something with two woofers if possible in a 2 way speaker. I have seen some good woofers from seas or peerless but I can´t really say that something is fitting.
Hallo again,
I decided after some time to continue with one driver from SEAS an 8inch with 93 dB ef. thats goes up to 2000 Hz so I can make a high impedance speaker of 8 ohm. It has a Fs of 29 so I think it can go low enough in a transmission line.
I can continue from there at 1800 Hz with the Air motion transformer, but I have to cut it since it has high efficiency.

promitheus,
which AMTs did you buy?
In the current issue of Klang+Ton, there is a project for an active speaker with the Eton ER4 AMT. There were passive versions also this year (Duetta and Duetta top).

I have been working on a 2 way TL design with the Heil AMT. I am going with a very wide range woofer from Eminence that goes up to 10K. I am planning on letting the woofer run free and using only a 6db high pass on the AMT.
I had a question about the phasing and was told to align the AMTs diaphragm over the woofers voice coil.
