My DIY speakers "J&N"

[MrBoat]

Let's do that,
you use a word "mold " which makes me think you want to tell me the following - meaningless work ,do you really think so?

Not at all. It just lends itself as a mold by default. It happens with many things that are built like this. Part of why it is great to make these things!

 

[MrBoat]

Ever considered tackling a project like this? You clearly have the skillset.

I make things with these concerns as part of my day job (mostly with metal) which is why this person's cabinet frames interest me perhaps more than the beautiful skins on the exterior.

I have thought about building speakers like this, but they would be a bit too rich for my home, and very few people I know would appreciate it. Then I would have to build an acoustically favorable space in which to get all of the audible benefits from such detail. I would emerge 5 years from now with glassy eyes and a bad need of a shave!

Obviously there is some language barrier, my English is not good, I do not know how to comment on situate, maybe at this address you will find some of the answers:

Your English is fine. I agree with, and understand your explanations with what you have presented here.

Also we have a member here (TLS guy) who gives very detailed explanations of such things periodically.

I don't think you understand. We're complimenting your work and looking at the beautiful design in your bracing. did you not use the bracing as a mold also to shape the speaker?

Wonderful I think that explained the situation to myself!

In spite of the audible contributions of the bracing, if one were to stress foam, veneer, or any other semi-flexible, otherwise flat skin over a frame work without adequately spaced supports, the skins may take on the look of a "starving horse," for lack of a better explanation.

I know you understand what I was saying. Just stating this here again so that the builder may get what I was saying, or that this was not a criticism.

Oh, I appreciate it. Some of my comments kinda double as questions too.

Okay, if you understand my construction in this way, what can I say?
It is my another "Home matrix":
Maybe you it know -bended 8 layers, 4 mm beech plywood?

 

[jororaitchev]

^And a little more on the subject of bending. We all know what is the ideal shape for the speakers. For technological reasons, it is difficult to do, especially with three tape loudspeakers. I strive to make the second most effective form - the egg.

I think I understand your construction. There seems to be some confusion on your end as to what I mean. This is what I meant earlier when I said I think we're having a small issue with a language barrier. Not that your English is bad, just some comprehension issues. I'm not questioning any of your work. I'm admiring it.

What did you use to bend the wood for your speakers?

My obviously it's I cant good at explaining to you , sorry!
Just three steps up if you get back, you will see my" home matrix ", it is a metaphor. I bend the material on it.

I can not answer the questions of several people, sorry!
i am not remember to say that I would not use soundproofing foam.

How did you make the shell of the egg? Lots of layers of very thin wood tortured around the frames?

If you were living in Bulgaria, i would have made a bet train cistern with Bulgarian beer/ could be wine ,but I'm not such a person View attachment 21002 View attachment 21004
I have to remind you, this is the initial stage of the project.
If you allow me, can you tell me how I measure the Internal volume- VAS ?

You did not answer the question.

 

[MrBoat]

You did not answer the question.

I do not know how you measured the internal volume? Fill it with beans? Most engineers can click this out on a computer in a short time these days.

Now I understand! Sorry too for being a little thick and not understanding.

You did not answer the question.

I do not know the answer to that question, but someone here might. Just hang tight.

I am an electric engineer,assuming I use a program (CAD ),entering data into this complex, incorrect form would take me a very long time, effort which for single production makes no sense..
The making every detail is unique, It is normal to have differences between them.
When assembling the structure, i do extra work in the interior of column, which changes volume.
It's clear that the software will not help me,mathematics - as well.
I'm trying to get closer to her alternative - the egg, so I solve the problem /as possible/with Fb ,Fc. My project is at an early stage and do not have , will not matter unless I get the right volume.

Yours assumption about volume measurement is а wrong.
