My DIY speakers -"J&N"

[Dj7675]

Great looking speakers. After just seeing the picture, my first thought was hmm that looks like a JBL TI6k... then I read your description. A great job.

 

[jororaitchev]

Cool!
I know a guy here in Sweden that built the larger Ti10k , and also TiK-sub replica.

My project has nothing to do with JBL except the idea of a form / created by a Danish dizajner /. "TI6 K" cannot be compared in sound to "J & N", the quality of the "my "speakers is much higher.

 

[jororaitchev]

What do you have now? Seems a shame you don’t have them anymore, but hopefully you’re about to show us your current speakers which are equally impressive!

Thanks!
I'll show you only projects, I don't have a ready audio system and I'm suffering!

Thank you for appreciating my DIYer work!
Expect other projects of mine, you might find interesting.

 

[jororaitchev]

Beautiful work!

Thank you!

 

[jororaitchev]

Wow, fantastic work!
Plus by having rolled your own, you're perfectly set up should one day you wish to try active amping them with some SOTA DSP correction and crossover! Years of fun and enjoyment ahead!

Thanks!
I do not intend to make active loudspeakers.. This project already belongs to the happy new owner, now I work on the rear speakers.

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.
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:

This is still an initial stage......more pictures;

That is some proper woodworking craftmanship!

Wow!

Gorgeous...
Take pride in those, they are beautifully done.

That is amazing woodwork.

I will show you one of my projects, which I had to change basically right at the very beginning - the back speakers ;
We all know, what is the ideal shape for the speakers- sphere. For technological reasons, it is difficult to do, especially with three tape loudspeakers. I strive to make the second most effective form - the egg. To begin with, I schematically design this way.I calculate the approximate volume, how do I find the right volume, will show you later in my project .
The loudspeakers are "SEAS"- Excel T25CF002 ", W18EX001- 6,5" . Everything is handmade, no "CNC" machine is used.
First option;

Тhe internal structure of the cabinets;

A few elements from the front panel processing;

 

[jororaitchev]

For the next stage / the shells of the cabinets / I made this "home matrix", with its help I bent 8 layers with 4 mm beech plywood;
PS
In fact, there is not much interest in my project, if you want a sequel, please visit this address -"Jorors DIY-Audio "in "Facebook"- the group is closed,please for your apologies! .
