Yes the render images are nice but you sadly cannot gather useful measurements from them. Karellen have you had time to listen to the mbl speakers? I am sure that they are simply attached to each other and the motor is on the bottom of both.

I bet you can; 3ds was fully compatible with autocad, so if you dowload the model, almost certainly you can open it on acad, and judging for the quality of the model the dimensions should be real.

but I just guessing

Default damping, compliance and density

Damping, compliance, density...
The neoprene is quite good on the three.

If the neoprene and the leather doesn't work well as inter lamelas sealant and damper, I will like to try something more advanced (and expensive), the sorbothane Sorbothane Sheets - 12" square, 1/8" thick | Edmund Scientific that looks like the neoprene, but with much better damping and compliance.
the problem is that maybe is very slow on recovering the shape...

I suspect that it is the material used by Mbl.

by the way... I've never had the oportunity to listen to the mbl speakers

Yes I know very well the Sorbonne product. I know factually that mbl does not use this in the current 101mkii. You are welcome to try it and show me. Sorbonne is also extremely heavy compared to other materials. The density is 1.28 g/cm cubed.

Default semi

took a couple of days to attach the lamellas and such. The process is pretty slow and stressful. I am pretty happy with how it turned out so far.

At first i thought you were building a spaceship, until i realised it was a speaker. Very ambitious and great work. So the question is, when is the group buy?!
