Interesting Magico news

I think it’s just a plastic dish of a specific size, which is likely filled with some damping material (of celestial origins no doubt). Here is a video of the S3; discussion (and picture) of the polymer housing for the midrange is at about 9:45 mark.

As stated above, many manufacturers isolate the midrange in a closed/damped housing or chamber.

@Melbguy1,

Yes, I know I was super-oversimplifying, in saying that the chamber looked like a plastic dish shape. 

I realize that their design goals and manufacturing tolerances are all done toward state-of-the art results. At this level and with this company, I'm sure that nothing is done/included in the final product that is not for an engineering, quality, [and resulting sound] reason.
