Before I start the comments in this forum I want to apologize for my poor English, do what I can!
Excuse me!

Thank you all for the good evaluation of my work, thank you very much!

In order to save time, I will allow myself a clarification:
-Everything in this project-idea, design filters the overall workmanship of the cabinets to the last detail was done by my hands.

 

Little later i'll show you how was made the speakers are made, step by step.

Thank you for your attention!

Excuse me for using a cliché; They sound as they look.

 They're already sold! The rear speakers (you have not seen them yet) ,are in the initial stage of construction - too.

Thanks for the good words!

I promised to  show you how was made the speakers are made;

First did this "home-matrix".

 

and for the center:

 

After, i bended 8 layers / 4mm / MDF;

After assembly, veneering with " Bird's Eye View", /  "Bird's eye " veneer/

The finish is 35-40 layers of acrylic auto varnish and after each layer- polishing in order to obtain this:

And now some pictures of the "dark side of the moon";    

That was all about this project. In a few days I will show you the rear- speakers project I am currently working on.
Thanks for your attention!

The name of this construction from "B & W" is:
 "Matrix? Internal bracing-system for cabinet stability" ,

 

  I will use my  term- "Ventilation".
Accept this term as a metaphor of a vented inner structure of cabinet , / I will say in a different way /,  has the task of preventing the column's own sound and participating in the design process.

Pay attention to the most important tool/ it's a metaphor/- the panel behind of the tools, it's my job too - I must finish her,after for some time .

Why and how should a beautiful project be changed at the outset?
The problem is in the frequency of around 5000Hz; There is a peak ,which strongly influences the average frequencies.There are two ways to solve this problem:
- Adding one more MW,
-More complicated construction of the filter I don't know the exact name , maybe (reager).
This project may be look beautiful, but will be changed.
As I wrote at the beginning of my post, everything is done by me, I do not use ready filters / and I do not recommend it to anyone unless it is a ready-made kit with cabinets /.Will try to explain why this project is  had changed at the very beginning.These speakers are made of a specific alloy and have their own characteristics.

 

Characteristics of the speaker in 55 liters closed volume:

Characteristics of speakers with and without filters:

Transmission characteristics of speakers:

 

What should I choose in this situation?
-1 option, add one more 18 FX001,
-2 option,remove one 26 FX001,
I chose a new progect with 4 identical speakers:1 ? 26 FX001, 1? 22 FX001, 1? 18 FX001 , T 25 CF002
 
 

 

 

[jororaitchev]

Rear- speakers project - early stage;

The loudspeakers are "SEAS"- Excel T25CF002-1", W18EX001- 6,5".Oll is made by hand, not used "CNC" machine.
