Hello Mihail!


This is Peter Avgeris from Athens, Greece.

I am so happy that I have met you here on internet after almost five years.

I hope that you are doing good. I still remember your magnificent loudspeakers with wooden cones that everybody around was fascinated of their extraordinary performance!

Your name came into my mind one month later, when I had sent you the first message. You are the only person around who could help me in order to reach my task. And it is not an easy one... I would be very much thankful if I had your reply any time soon. Actually I would like to have your opinion and - to be honest - I cannot trust anybody around except you, because you were always speaking as things are in reality.

I am about to metarialize a power amplifier with around 2.3 W RMS power output. It is a tube amplifier Single Ended. With such a low available power capability, as you understand you need super sensitive speakers in order to achieve life like SPLs. There is a company here in Greece that manufactures one of the best speakers I have ever auditioned. Their website is www.arcadianaudio.com you can visit it and have a look to their design. I have listened to this speaker extensively and it sounds really different to any other design. And as you understand, there are quite a few reasons for this. This speaker is originally equipped with AER MD3B, not the best loudspeaker around in terms of fine musical textures, decay of harmonics, etc, but indeed I could not expect such a sound caming out of this AER driver. The speaker itself does not have any flaws at all and it does not sound plastic or artificial in any way, like the commercial Avant Garde speakers (terrible sound!).

Searching for an alternative solution, the manufacturer who is a friend, told me that I can use any driver of size comparable to Lowther PM2 or PM5 but not a field coil version like Voxativ. The magnet depth needs to be not that big so as to be accomodated inside the speaker. Besides Lowether PM2 & PM5, there exists one version of AlNiCo full range driver, manufacturer is Voxativ. The version is
http://www.voxativ.com/ru/shirokopolosnye-dinamiki/ac-4a/
which can be accomodated. This speaker does make use of wooden cone!!! Now as you see, they are making clones of your idea! They copy Michail Urakoff !! They claim that the bass performance is extraordinary with wooden cones, very much close to your writings! Of course I have no reason to question on this. This driver seems to be really interesting.

Now, let's come to the conclusion. I know that you have been making wooden drivers for long. If there exists one person whom I trust, this is you. I would like to ask you on the following:
•Do you think that in an enclosure like the one of Pnoe loudspeaker of Arcadian Audio, any driver like Voxativ with wooden cones, would benefit in the whole spectrum of sound or maybe it would be an ideal solution for bass only and in mid freq there will be a compromise? I remember that you had transformerd Lowther speakers to wooden cones but did not remember your opinion on this.
•Voxativ has wooden cone and paper whizzer, obviously for better HF extension. Have you ever had any direct exposure to such a combo? Wooden cone - paper whizzer?
•Permanent magnet loudspeaker is not a favorable option for me because I have played a lot with field coil units. Lowther from UK can give me the baskets plus the paper cones for no more than 400 GBP per pair. If you think that a wooden cone like Voxativ's would be the perfect solution for this Pnoe loudspeaker, then the next question is whether you have made or if you keep making wooden speakers, In case I could have such a solution from you, I can have the original voice coils and suspension foams and baskets, shipped by Lowther to me, that means you can make the wooden cone transformation and thus I can have a dream speaker. The field coil assembly for me is something very easy to elaborate.
•So in the end, the question is if you can help me manufacture a pair of drivers, baskets made by Lowther, original 16 ohms voice coils by Lowther, wooden cone by you, paper whizzer by you or Lowther, field coil motor by me (easy!). Last question has to do with the spider and suspension rim. You have played with soft leather on the rim and carton or phenolic spider. Would you suggest anything on this? Maybe leather rim, carton/phenolic spider?


As you understand, you are the only person who could give me any reply to my hesitations.

I am looking forward to receiving a reply of you, with utmost interest.

My best regards from Athens.

Peter
