Few DIY projects

[Folsom]

Cool idea for the crossover.

I previously make the last layer-10 mm MDF / to get a sandwich construction / on the front panel and the bottom and of the top.
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 ...

 

[jororaitchev]

Clarification, this is a polyurethane primer, I will be make veneer on the on cabinet's with "Birds of Maple".
The first home tests are good.
My current surround speakers of " Technics" CA-10 with a good sound from 1997, they are sadly retreated himself ...

 

[jororaitchev]

After the measurements, this is are Technical data:
Frequence Range; 33-25000 Hz
Long term Max Power; 200 W
Crossover Frequency; 2800 Hz
Impedance; 4 Ohms
Sensitivity; 90 db SPL
Cabinet Volume; 31 L
Gross weight / without stand /; 27kg.


This is the project of the rear speakers, will finish it with "Bird's eye view". There will be a sequel ...sometime..

A very underestimated moment - work with multilayer MDF!

There's still a lot of work on the stands.
I show you a few pictures of the front speaker bases, the rear speaker stands will look like the same;Always been a problem with the MDF, especially when we have a multilayer construction. Over time, individual parts are beginning to show up - all of this is the result of improper processing. Soon I will show you how to deal with this problem.

These days I remembered that I did not discuss my veneering technique with natural veneer for cabinets with a polyurethane varnish base. Like this pozicion-1
how i maked and finish in pozicion- 2?

Your woodworking is awesome! Thanks for posting!

I've only done simple 2-D veneering, that looks like a challenge...

Thank you !
I don't know to exist 3D veneer - I'm kidding!
Showcase your work, if you wish, I can give you useful information.

I show you a German site, that offers such "DIY loudspeakers -cabinet " and please, for your attention, they want money for such a product;

A look at the room where I listen to music/everything you see is created by my hands- fact!/;

The front of the stand is treated with 3 mm MDF;




Next part - painting with acrylic spray, I need to get an idea of the lines of detail (they are many) and how they will look with the acrylic
auto varnish;

I like (admire) your wood-skills & perseverance & multidisciplinaire tech. in the (home) field (even your audio scène) .....
Congrats for your project.

(one note: be careful with issues difference dilatation coefficients & home temp/Hr...)

Not everything is as easy as it seems, the problem with the seasonal movement of MDF material is not to be underestimated! Typically, problems with the multi-layered construction of MDF details occur after several seasons, I'll show you how I handle this task:
On the first photo, we can see the hidden problem that will appear in a few years is very well.
I show my way of dealing with this task;
