Interesting situation!
 My completed project"J&N" is much more interesting for you ,  than that with the real speakers, but is this a "DIY - audio" forum?
I use personal methods with to build my speakers and  i share it with you  and  expect  a lot more questions, but reality is different. Perhaps there is a language barier, with common effort, it can never be a problem!

No, Joro, it´s not a specifically DIY - audio forum, it´s only one of the threads in this forum here.
For one or the other here, there may exist a language barrier.

Well, you´re expecting some question, here are one ...
Do you have any measurements for us, like this one from our colleague tiarez ...

Your comments made an impression on me!


All my measurements, for  all my speakers (so far), I did at DIY labs in BG. I've always had problems documenting my measurements. It's happened was so that documenting the measurements, costing me extra costs, I did not accept it and that's one of the reasons i haven't a graphics.
A week ago, I ordered from the Netherlands "OmniMic V2"-Dayton audio Precision Measurement System, and then- maybe a month, I will give you detailed charts, but you say I'm not in the right forum.
I very much hope not to sound rude- as an advertisement, but I tried to publish my projects at the" https://www.loudspeakerbuilding.com", the most kind thing that was published for my projects was- " he does not speak foreign languages, it does not make sense of discussion, with hime..''- of course in German".
I would be grateful if you would give me a true DIY- Ge. forum address, please personally!

I think, Joro, youre not in the wrong forum, be assured that a lot of us have an eye on your projects, we look , and we appreciate!
No need to change the place, and there won t come too many questions because of a lack of interest, but because of your exactly describing pictures and explanations, so you leave not many questions "open". Anyway, im interested in the "birds eye" material that you have used, what material is it and how did you fix it on the mdf surface? Regards to Sofia, Bulgaria..

[HaiEnd Verweigerer]

I hope, Joro, even when you´ll find a special DIY Loudspeaker Forum that you stay here too.
Your project is very interesting for a lot of people here.

Thank you for the good evaluation of my work and my DIY projects!

I do not want to leave this forum / here for the first time I have had normal contact with lovers of DIY -audio in Germany/ .

Here, this is a really right question! Unfortunately, I cannot answer of this question  in one sentence!
The natural veneer can bend tangentially or radially, I bend it and diagonally.I can describe in detail how I work with veneer, but really, my technique is very complex and requires a lot of experience, sorry!

If you wish, I will describe my technique in detail, but I do not know whether it will be an interest  for others?

Your theme, your project has already 2.594 Visits, from 14.01.2018 till today.
So you see, that a lot of people here are interested in your project.
-even when not so many questions about it reaches to you.

[jororaitchev]

Tatsächlich ich habe nicht die ganze wahrheit gesagt,  Ich versuche es  auf kommunikativer ebene Deutsch zu lernen, das ist extrem schwierig für mich. 
 Ich habe das forum auf Englisch benutzt, aber wenn du es mir erlaubst,   mit Ihrer hilfe, Ihrem wunsch und vor allem geduld möchte ich meine kenntnisse auf Deutsch verbessern.
Ich werde Ihnen ein komplexes projekt zeigen, dass zu beginn viele veränderungen erfahren hat, hier ist es;







P.P. Kein Kopierer wird verwendet, alles wird manuell erledigt.

[jororaitchev]

Warum und wie sollte ein schönes Projekt von Anfang an verändert werden?
Das problem liegt in der frequenz von etwa 5000 Hz; Es gibt einen peak, der die durchschnittlichen frequenzen stark beeinflusst. Es gibt zwei wege, dieses problem zu lösen:
- Hinzufügen einer weiteren MW,
-Mehr komplizierte Konstruktion des Filters Ich kenne den genauen namen nicht, vielleicht (reager).
Dieses Projekt mag schön aussehen, wird aber geändert.
Wie ich zu Beginn meines posts geschrieben habe, wird alles von mir erledigt, ich benutze keine fertigen Filter / und empfehle es niemandem, es sei denn, es handelt sich um ein vorgefertigtes kit mit schränken /. Versuchen sie, dieses projekt zu erklären die lautsprecher sind aus einer bestimmten Legierung und haben ihre eigenen eigenschaften.
 
Eigenschaften des Lautsprechers in 55 Liter/für zwei lautsprecher -110l./ geschlossenem volumen:

Was soll ich in dieser Situation wählen?
-1 Option, fügen Sie einen weiteren 18 FX001 hinzu,
-2 Option, entfernen Sie eine 26 FX001,
Ich habe ein neues Projekt mit 4 identischen Lautsprechern gewählt: 1? 26 FX001, 1? 22 FX001, 1? 18 FX001, T25 CF002

Und noch ein paar grafiken;

The skeleton reminds me of that:

Really a lot of work you invest in your speakers! How many Kilograms has one at the end?

Yes, "High-End" dinosaur!

Thanks for your good evaluation!
In fact, this inner matrix is designed for a volume of 240 liters and weighs 25 kilograms.
The exact weight of the loudspeaker, I can not say how much it will be, finaly.

Ein paar mehr Fotopositionen;

Ich sehe meine Projekte immer noch überwacht, vielen Dank für Ihre Aufmerksamkeit!
In diesen Tagen fiel mir ein, dass ich meine Verblendungstechnik mit Naturfurnier für Schränke mit Polyurethanlackbasis baze nicht diskutiert habe. Wie diese pozicion-1, wie habe ich in pozicion- 2 gemacht und beendet?

Looks gorgeous

[Svennibenni]

it really is fascinating what you accomplish with those crude tools you showed on the other picture.
How much time do you spend building the wooden frames ?
In germany this kind of work is hard to find these days

... In germany this kind of work is hard to find these days

I would say, this kind of work is almost not to find ..., and yes it´s really fascinating!

Thank you for the good words!
Unlike Germany, such "idiots" as my personality are not uncommon in Bulgaria. Our generation grew in very difficult conditions, we were forced to do everything in our live with owns skils,  there was nothing in the market, I know that  it is difficult to comprehend, that was the truth .In oure contry no furniture, building materials, even 
the simple alkyd matt paint,  we  maked  with his own hands. In DIY, time doesn't matter!

Vielen Dank für Ihre Aufmerksamkeit für meine Projekte! Vielleicht ist das Forum nicht "DIY", aber ich sehe, dass Interesse besteht, werde ich weiter veröffentlichen.
