My DIY speakers -"J&N"

Thanks!

This is the technical characteristic / I will publish the diagram later /; SEAS" - Excel / Tw-1 ", Mw-5" for center 2x 5.5 ", Bass-8.5" / and cross-over parts- "Intertechnik". Nominal impedance- 8 Ohm Frequency Range 30Hz-20kHzCharacterstic Sensitivity (2.83V / 1m) - 87db Long Term-110W. 
I think you've already answered for yourself what the sound is.

impressive, I would like to know more.

Thanks, you will learn!

They look amazing, whats the finish on them?

Thanks!

You will surely understand, a little patience, please!

That is some beautiful and skillful workmanship! I can imagine why most woodworkers would balk at trying to craft such a 'box'!

Truly stunning speakers, and that's the first pair you have made, unbelievable.

My apologies, missed the centre speaker.

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;

No, carry on.


I designed a couple of speakers years back now but I had a mate who was a cabinet maker by trade to build them for me. I did the soldering, that was it.

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.

Due to the complexity of the process, i will pay close attention to it. My technique is complex, risky on a large scale and I definitely do not recommend it to enthusiasts with little experience! A natural veneer can bend tangentially or radially, usually masters prefer to work in just one direction - for less headaches.In my method of processing, I use both bending directions simultaneously, but add a third diagonal bending.

The other main problem is the adhesive with which it sticks the veneer, it is polychloroprene, this glue does not allow you to move the veneer, once touched to the base there is no other chance-stays there. If you try to move it, you will break the veneer at the moment, and when we talk about "Birds of Maple" with a price over 40 EUR, the feeling it's not pleasant!

I will explain my technique for cutting veneer before gluing it.

On the finished cabinet of the loudspeaker, from " India paper" / she is the closest with the veneer / I make the templates that should lie perfectly on the base. The problem is in the wrong shape, the veneer after gluing in one part, changes his shape, although everything has previously been matched perfectly. It requires a lot of attention, patience, and proper judgment, which part should squeeze, otherwise balloon spaces are created, which are very difficult to correct without being visible later. Sometimes, depending on the type of veneer, moistening helps, but this action also requires judgment with experience.

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

I will say it again, well done and a great job, of course I do not know what they sound like, I am sure looking at the build, it will also be impressive. It reminds me of another self build, a copy of a Focal La Scala which greatly impressed me also, this is the speaker he copied www.secondhand.hk/c/electronics/consumer-electronics/other-consumer-electronics/focal-scala-utopia-iii-reference-full-range-speakers/
