My DIY speakers -"J&N"

Well, a legend, I'm not a JBL, thank you, very much!

 

There may be a language barrier here, sorry!
Thank you!

 

Thanks! You don't have my age in mind, do you?
I'm kidding, this is my "Copy Center";

 

While you have some incredible skills as a craftsman, you are indeed, a true gifted artist.

Exquisite work by anyone’s standards, Georgi!

 

Most excellent! You are a true craftsman.

 

Thanks for your rating, thank you very much!

 

Thanks!

 

So, I promised to continue the presentation on building my speakers.
I understand that this is not a DIY- speakers forum, but with this post I am trying to provoke in you a desire to build your own loudspeakers, if I succeed with at least one member in this forum, I will fulfill my mission. Thanks for your attention mission!

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;

Тhe result - shells;

 

@Georgi Tsvetkov just one word- amazing work there Sir!

 

Thanks, Andy!

 

Wow! Mad respect to your wood working skills. They came out amazing.

 

Congrats and nice looking speakers. That the same woofer I use on my Rauna and they sound really silky with a punch!

 

Thank you!

 

Stunning

 

Thanks!

 

Thank you, I'm glad to you have SEAS speakers!

 

A few more photos;

 

I am approaching to the measurement of the internal volume of cabinet;

 

- My method of finding an internal volume of a complex construction was discovered about 2500/ from the Archimedes genius/.
The volume per liter of water is equal to the volume of 1 kg. and 1l. Water = 1 kg,
-their specific resistances are the same, with very little error.
I will say it in a more understandable way:
- if we have 20 liters of water in a bucket, this bucket will weigh approximately -20 kg.
- if we have another liquid in this bucket, we may have 20 liters, but we will not have 20 pounds.
In my method of measurement, i do not immerse the inner construction in the water, just I measure the weight and deduct it from the total volume.
There is no simpler and more accurate method for finding the volume of a complex body, the method of Archimedes is flawless!
P.S.
Sorry, that that I burden you with such information, but measurement is very important for building a column!

 

I am approaching to the measurement of the internal volume. From waste material I made this gadget ,that takes part in the measurements and when assembling the cabinet;

 

In this photo the red line is the waterline, the vas of cabinet must be fill with water next to it / everything must be perfectly leveled/;

 

Let's assume that the density of MDF is 0.75 kg. of cubic decimeter/ average value by tables /. This is 75% of the actual reduced volume. The reduced volume error is: 3.5 / 0.75 = 4.6 liters actual reduced volume, and the whole volume is 43-4.6 = 38.4 liters. The total error of 39.6 liters is 1.2 liters or -3.1%. The ways to reduce the insaid of volume, are incomparably easier than the increase, the point is that this is the desired vision and the compensation must be done inside the volume. At this volume, I can safely mount another W18EX001, i. we are talking about a 2, 1/2 tape loudspeaker and that sends the project into an initial phase.
The old project stayed in the past ...
