Will do karellan. The amount of variables for the lamella are high so testing and perfecting is going to take some serious effort. Other parts of the speaker of also part of the plan further down the line. There are some good ideas for sealing and such.

The testing stage is officially here all problems that hindered me in making a very accurate, reliable, and fast speaker have been solved. This New build will be a test of all of this after that changes in materials and construction will be tested and results will be shown here along with a recording.

Thank you Karellan. The process is working great although I did find a few kinks that werent anticipated in real life assembly. This will no doubt be the best most accurate assembly. The first few test will show a difference within the same mid-range unit. changes in "additions" that will will show a before and after effect. The ones after will be a whole other mid-range with a design that should increase sensitivity.

The seal between lamelas looks very good
Very good craftmanship.
How it is done? Some kind of EVA?

Thank you karellan the amount of craftsmanship needed is insane. The amount of research and development needed to make a system to allow for the perfect alignment of all elements far exceeds it. No it is not EVA. It is in fact Neoprene foam. There are several tricks in building this thing that one only will truly know if they build it and research the heck out of it. The actual alignment system I use is in my opinion a little more "correct" than mbl. All from what I seen tells me they may be a little out of plumb so to speak.

Very nice build quality.
Did you test each petal for equal tension under compression?
I would think any deviation would cause the coil to rock if they were not equal.

Regards
