You always have to start with a simulation somehow, I start with cardboard boxes , I'm currently working on a project with a sphere - again with cardboard.
The acoustic center is always neglected...

When constructing the cabinet of a loudspeaker, must be found determine speaker acoustic center.
First of all, determining the speaker acoustic center is useful when designing loudspeaker...

Actually, I was trying to answer you at the moment, but the distance certainly speaks for itself. This is my legal system for measuring my speakers;

It was hard for me to take it in too, but my source is very, very into things, I can send you his personal blog if you want.

You are welcome, during this time there is a change in the design of the labels that stick on the magnet on of drivers, always such changes made for me suspicious!

I know in detail the production of SEAS, these are very good drivers that allow the construction of projects with loudspeakers above the HI-FI mid-range. I have measured over 40 from the same ...

After the measurements, this is are Technical data:
2½- way surround loudspeakers,
Frequence Range; 33-25000 Hz
Long term Max Power; 200 W
Crossover Frequency; 2800 Hz
Impedance; 4 Ohms
...

Oh, i forgot to show you what I make for the filter compartment!

Housing assembly;

After preprocessing of the internal ribbing I can now start collecting the cabinets;
Now I can make the exact measurement of the volume.
And that's 31.5l, just as much as I need! Further processing...

I am writing to you as a person with over 40 years of experience in interior design, the construction of sound systems is not an activity in itself, especially when significant amounts of financial...

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...

- 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....

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;

Thank you for your evaluation of my work, Mikado463!

Thanks a lot, BobInWI !

Thanks, JayT !

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;

A few elements from the front panel processing;

Тhe internal structure of the cabinets;

I will show you one of my projects I had to change it , basically right at the very beginning - Rear speakers -”J&N”sr.
We all know, what is the ideal shape for the speakers- sphere. For...

Thanks, Porsche!
It is possible with this graphic to get an idea of the sound;

After veneering the next steps are, to make the desired color , and the following finish manipulation , spraying with high quality automobile acrylic lacquer. To obtain the desired gloss, after about...
