Thanks!

Maybe you missed the stage of my posts, please see page 8!

Speakers is a 2  1/2- way, crossover is combination of a series for upper bass and treble added a parallel filter for lower bass.

P.S.

W18E001.                        W18EX001

QTS- 0,42.                          QTS- 0,26

Thank you for good evaluation of my work! Ihave long been thinking about chainging the Tw with " crescendo" -SEAS. I have always wondered why SEAS do not offer this one Tw in a similar color of "Excel"- obviously a not well thought- out commercial concept.Agree with me, that these columns will look more lnapproprite with the color of the "crescendo"

Clarification, this is a polyurethane primer, I will be make veneer on the on cabinet's with "Birds of Maple".
The first home tests are good.
My current surround speakers of " Technics" CA-10 with a good sound from 1997, they are sadly retreated himself ...

After the measurements, this is are Technical data:
Frequence Range; 33-25000 Hz
Long term Max Power; 200 W
Crossover Frequency; 2800 Hz
Impedance; 4 Ohms
Sensitivity; 90 db SPL
Cabinet Volume; 31 L
Gross weight / without stand /; 27kg.

Several steps to the moment with measurements ...

Nebih se bas slozio sa ovim. Dokazano je mnogo puta da se do kvalitetnog zvuka ne dolazi samo metodom upotrebe mrtvog materijala za izradu zvucnih kutija. Nekada to zna biti kontraproduktivno pogotovo sa upotrebom medijapana. On zna nekada unistiti svu zivost glazbe.

Масивно дрво; буква, храст или егзотични, нису врло погодни за колоне. Има сопствени звук, који је минус, а због његове недоследности се не препоручује, посебно за предњи бик са великим отворима.

It is filled with deep knowledge - from mathematics to marketing.
Thank you very much, I even realized that myself I is made in the wrong way!

Such a design- never!They look like cut trees in the park.

Massive wood for speakers - a very bad idea!

Nhf , stalak je kvalitetan , al  meni estetski nije nešto  lijepo .

Relax , there is a lot of work still on the stand!
Similar was the situation with the bases of the central pillars;

And a risky picture (everything is supported by gravity), how look for compared to the front speakers, are not on one line, but I rely on your imagination.

A small structural change for the side panels, last layer is 1 x 4 mm plywood and everything is re ady for the measurements.

I continue with the collection of the cabinet;

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 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;

I have an idea to make a new project to in the base there should be two 10" loudspeakers - just an idea. They look like animals, maybe dinosaurs, but important are 20Hz.

And the original model will look like this;

Preprocessing of the internal ribbing;

I can now start collecting the cabinet;

Finish the speakers until September the 30th and bring 'em over here to diyaudio fest.

There'll be some nice brandy - for sure - and fried trout, barbeque, and a lot of good sound

I will certainly do so on this date, but I have not specified which year will be .

I'm sorry, some total trickery with my the server and the internet!

My brandy is 50 degrees, but it's not the problem.

sqrt(Bravo)  for You Sichko - extremly inteligent.

But still I can not understand why are You registered on more than 40 audio forums?

I'm 57 years old and I have the answer is simple, I have a problem with my ego, but also with alcohol, my "beloved" state and the fact that I was not born in other latitudes.

I have registered in more than 40 forums, I have asked this question and do you know how many answers are correct? - 1, and this guy offered to fill the volume with beer!
There were variations with sand, rice, cat food ......

I will try to explain why exactly water?
1 kg is аpproximately equal to to 1l, ie. Their specific resistance is the same.
It is marked with the Greek letter "ro".
When you use dry sand (at least you have to wet it), you have to calculate this "ro", otherwise you will get a volume that has nothing to do with the correct answer.

P.S.

In your Croatian "DIY" forum, I have not asked this question yet, if you promise not to interfere, I will do it, and you will see the answers - the silent answers.
There was a some some movement when only when I published the filter on the my columns "J&N'.
If you are not registered there, please accept my apologies!

I was trying something like that but with dry sand. It was very efective and simple.

The moment has come  when i must find a volume of complex shape, before that I have to do some preparation. From waste material I made this gadget ,that takes part in the measurements and when assembling the cabinet:

I have to do some preparation of the details;

 On the sixth 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; 42-3,5= 38,5l, 4.5 l more than what's needed - what's next?
I know the total volume, now everything is very simple there are several options for correction;
- purely mathematical / small planarity, simple algebra and axonometry /
- methodically- it can be done in several ways.There are more options ..later.
