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

Good luck

Thats the price they sell it here. It costs allmost the same to buy it from US.

Promitheus:

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.

I really need some info on them.
Thanks

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.

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

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.

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.
