You made a real good job!  Thank´s a lot for sharing!

Thank you for evaluating my work in this way!

[/url][url=https://i.imgur.com/g9NkviX.jpg] I will show you one of my projects, which I had to change basically right at the very beginning - the back speakers , let's go;
The loudspeakers are "SEAS"- Excel T25CF002 ", W18EX001- 6,5" 
Everything is handmade, no "CNC" machine is used.

I'm impressed. Great work, Joro!

I'm impressed. Great work, Joro!

Thanks, there will be more!

[Mosbach]

No way

[HaiEnd Verweigerer]

I´m very impressed too!  
Seems like we will see soon the finished work of another great and well done job from you!

-and I´m very curious already to see the rest from your work.

[jororaitchev]

I apologize to all of you, but at the moment I have a very hard project and I have to do it by the end of this week! I'll get back to you soon.

No problem Joro, you have to set priorities.
I wish you success for your project!
We´ll stay tuned.

Es tut mir leid für den zweiten Beitrag, aber ich verehre Uriah Heep!

Finally another Uriah Heep fan (referring to the band in their Byron and Hensley days) 

Very nice work those speaker cabinets!

Unfortunately I am almost all fingers and thumbs when it comes to woodwork...

[jororaitchev]

So, I'll try to show you how I'm doing my projects. It is normal,  at the beginning of the project to be the idea. For me, the vision of the speakers was always the most important thing, my model loud speakers must have distinctive features and be easily recognizable. For this reason, I first paint and then calculate. This idea naturally creates many problems.The complicated form of the cabinet is difficult to calculate. When talking about industrial production of speakers, everything is clear, appropriate software and no problems with the calculations. But here it is about single pieces (for now) and I have chosen a different way of finding the right volume. I will show you step by step how I do my things;Naturally, I start with the matrix, with her help will bend 8 layers  х 4mm plywood.

Joro, what kind of tools/machines do you use to get the parts in shape?

I do not need many tools, this is my "copy center";

[High Fidelity]

Achieving good results with that, I like it!

There is another option;

Naturally, i  have  there are many more tools, but these are the main ones.

Joro, great respect for your work! Very nice results, the shown speakers are nicer than the original JBL models, which i saw in the net...
But by no means you should use a grinder as shown in the picture without any dust absorption for "forming" mdf or "Spanplatte" or even natural wood. This is not "recommendable" for use in closed rooms, you will inhale far too much dust, and it should be asked if its worth the danger...

Thanks!

Actually, MDF processing is the most harmless. The particles of beech and oak are far more dangerous. I have already gained experience and I am trying to protect myself.

I know the approximate volume of the cabinet, but not the exact one. I'm  starting to prepare for  to measure .

[jororaitchev]

At the first photo, the red line is the waterline,must be fill with water next to it / everything must be perfectly horizontally!/.
I measure the weight of the my vented inner construction - 3.5 kg.
-The amount of water is 42 l. in the box; the average value relative to the density of MDF is 0.75 kg. of a cubic decimeter,3,5/0,75=4,7l, 42-4,7l= 37.3l more than what's needed - what's next?
The problem is that my investor likes the vision of the column.The decrease in volume must occur inside the construction of the cabinet.This sends the project in a more initial phase,we have a new requirement for the project, another W18 EX001.The old project stayed in the past ...
And this is the new interior design;
  

[jororaitchev]

After preprocessing of the internal ribbing I can now start collecting the cabinets.


Now I can make the exact measurement of the volume.
And that's 31.5l, just as much as I need!
Oh, l forget to show you what I did to get that volume!
I maked a filter compartment (for the MW and TW), the W section will be in the box;

I am distracted, excuse me!

I previously make the last layer-10 mm MDF / to get a sandwich construction / on the front panel and the bottom;


Last constructive action ;  

After 10 hours I will install the last layers of 2 x 4 mm bent MDF.
