I see that I have 330 visits to my post, so I will present to you the story of the design and production of these speakers.
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.I didn't use a "CNC" machine and
3D program.
“J&N”- front speakers and center -step by step;
At first, I had to figure out how to bend MDF plates. In the internet now has a very detailed material on how this process is being carried out with complicated multi-operative press mashine, but 2009 this information was scarce and irrelevant to me because, its clear I can not make a similar device at home.
For this purpose, I made this "Home Matrix" for the center and front speakers;

On these matrices I bended 8 layers of 4mm MDF. The adhesives I've used will be discussed at a later stage;

My initial idea was, for a bass speaker 6.5 ", but once I assembled the pilot model and measured the internal volume of the cabinet, found that I had enough reserve even for a
10" speaker. I decided at this stage to use 8.5 ". This is the first option;

The veneer I use in Bulgaria is known as "Birds of Maple", in the world is also known as "Bird's eye" . We reach the moment of very specific activity - veneering with natural veneer. When veneering panels, details is in one plane, there are no problems. There is only a requirement - the person who collects the individual pieces has good skills, the rest is completed by the pneumatic press.
When we talk about a complex shape, our immediate association is for "Vacuum press", but there is a limit to the thickness / height / of the workpiece. If we are talking about veneering of a flat surface with motifs on the surface - it does work, but if it is another massive form dont.
