DIY my dream come true and ...go!

[jororaitchev]

... And in order for the situation to be more interesting, I decided the speaker would be 2.5 bands

 

[jororaitchev]

Preprocessing of the internal ribbing;
I can now start collecting the cabinet;

 

[jororaitchev]

I have an idea to make a new project to in the base there should be two 10" loudspeakers - just an idea. They look like animals, maybe dinosaurs, but important are 20Hz.

Absolutely masterful cabinet work.

 

[jororaitchev]

Thank you for the good evaluation of my work!

And the original model will look like this;

Why two midrange drivers?

Why two midrange drivers?

I think everything is explained in post # 74, but you may not have come to it.
So, especially for you;
SEAS Excel W26FX001has a sensitivity of 87 dB / 2.83V, m /
2 x W26FX001= 90dB, 1x W18EX001 has -88db, that is, at the one same level of volume amplifier, we will have more bass and we will not have enough environments. For this reason, I even wonder if I cannot change the highs with
T29CF002.

Shouldn't baffle step compensation require that woofer sensitivity be higher vs mid/tweeter?

continue with the collection of the cabinet;
Now I can make the exact measurement of the volume
And that's 31.5l, just as much as I need!

Oh, l forget to show you what I did to get that volume!
I maked a filter compartment (for the MW and TW), the W section will be in the box;

previously make the last layer-10 mm MDF / to get a sandwich construction / on the front panel and the bottom;
Last constructive action ,I will install the last layers of 2 x 4 mm bent MDF.

It's almost a pitty you have to cover the inside, it's a piece of art on itself! Just beautyful.

Thank you!
In "DIY speakers" sometimes beauty is made inside, but it is "heard " outside.

 

[jororaitchev]

A small structural change for the side panels, last layer is 1 x 4 mm plywood and everything is re ady for the measurements.

 

[jororaitchev]

And a risky picture (everything is supported by gravity), how look for compared to the front speakers, are not on one line, but I rely on your imagination.

 

[jororaitchev]

Several steps to the moment with measurements ...

Nice job with the white finish!

No, it's not a finish. Over the this white color will be finished with vener.

 

[Dudeisms]

These are not speakers, they are works of art!

 

[jororaitchev]

Thank you, but they are just in addition to the front speakers.

 

[jororaitchev]

Nice job with the white finish!

Clarification, this is a polyurethane primer, follows the cabinet's veneer with "Birds of Maple".
