Arenith, my mission is to help to the duers who want to make their own loudspeakers, I have no idea what the shape of your speakers is, if it’s an annoying prism, I can’t help you - fact! If it’s a complicated form - yes, you have a deal with me!
These are true pieces of art.
The results of handcrafting like that can not be compared to EUR 300.000,- pair of speakers.
These are unique, undoubtedly must sound really good.
You are blessed, with unique skills, a wife to support such endeavor and the discipline to carry such project through.

Thank you, my speakers cost about 3700- 3900 EUR for per, unit count and with the highest quality elements in the filter and loudspeakers of “SEAS”.

I will start the presentation with one project, which is in the initial phase, but has undergone several conceptual changes-“J&N”-2.
In order to save your time, I will allow myself a clarification:
-Everything in this project- idea, design the filters and the overall workmanship of the cabinets to the last detail was done by my hands.Not used “CNC” machine and 3D program, the lowdspeakers are- “SEAS-EXCEL”.
First option:
I started with measurement simulations;
N-1 graph characteristics of the speaker without filter,we have a peak of 106 dB.
N-2 graph shows the transfer characteristic of the filter in the frequency band 50-100 Hz is above the 0 dB level. It is useful to understand why in the passive filter the transmission ratio is greater than one? The answer to this question is given by a comparison of the input resistances . The minimum value of the input resistance of the speakers with filters (red curve) at a frequency of 90 Hz is 3.2 ohms. This is an acceptable value. If I select the cutoff frequency of the filter below, for example 200Hz, the input resistance will decrease to about 2 ohms. This will be too much load on the amplifier. The costs of creating or acquiring such an amplifier will be unacceptably high. A decrease in volume will also lead to a decrease in the input resistance, but to a lesser extent.
N-3 graph shows the sound pressure of 90dB of two W26FX001 speakers with a filter at an input voltage of 2.83V. It’s not hard to guess that if we simulate the filter for the W18EX001 speaker, we will get a sound pressure of no more than 86 dB at an input voltage of 2.83 V. If we remain in the concept of building an AS with filters on passive elements, we will have to reconsider the choice of the mid-frequency dynamics, or to refuse 1 woofer speakers- W26FX001.
My final choice is:
The template for the internal ribbing;
Side carriers;
And;

Your fit looks fantastic. Not an easy task with so many parts. Congrats.

very impressive!!!
Thanks, yes, apart from being a lot of details to make, they are also difficult to invent and construct!

Thanks, brian.fitterman!
Beautiful workmanship!
Very impressive! My grandson would love to assemble the skeleton!
Wow! Absolutely stunning work. Thank you for sharing.
You sir are a true craftsman!
Thanks, Baldy!
My grandchildren are involved in the assembly.
Thanks for your rating, I appreciate it!
Thank you very, very much!
Things is happen, albeit are slowly ;
Meet with my logo, please, it took me a long time!
…
Actually, I repeated the logo theme because I wanted to bring you back to the initial project, I have an upgrade as options, an upgrade of my hi-fi system, and I will introduce you some pictures of the room where I listen to music, everything in it is made by me, follows ;
I have some breakdown in communication, I beg your pardon!
