Interesting Magico news

Yes melbguy thanks. It appears that even a company so focused on aluminum recognizes excellent enclosures can be made from other materials; as Wilson has advocated the benefits of composites and used them for years. Interesting departure for Magico I feel, and sensible. But I wonder it detract from the "permanence" of the all-metal efforts?

Thanks melbguy. I looked at the graph and comments.
They claim " The unique shape and carefully chosen materials, when combined, create the ultimate "sound pressure absorption device.".
I can't help comparing it to B&W's very simple 'tapered tube';which they claim
" Nautilus tubes taper to make the sound from the rear of each driver disappear."
I can't understand a containment device being a sound pressure "absorption" device,except in a very limited fashion - compared to B&W simple system, using the horn principle in reverse.
.

"Big money doesn't equal great sound". Unfortunately.

Without precisely addressing the "damping" properties of their 
polymer sub enclosure-- as the 
"specs" of the polymer are unknown to me-- I feel the shape of the
sub enclosure is of more benefit in breaking up other backwaves in 
the overall cabinet enclosure, rather than benefiting the elimination of the 
mid range backwave. Here is a paragraph from a piece done by Doug Blackburn
which I find appropriate and succint;
" Undamped backwave energy can bounce around inside the speaker several times, eventually hitting the back of the driver’s cone again. When the backwave hits the back of the cone, the cone radiates some of that sound into the room as distortion. The backwave sound is delayed and decorellated. It is no longer related to the sound on the original recording; it has become distortion. The delayed backwave sound did not exist in the original recording, and this makes it distortion."
The laws of physics are what make cones radiate the same amount of 
sound to the rear as well as the front.
Perhaps Magico has a magic stuffing material?
Where does that energy go?

Thanks hc707. Agreed re speaker building 101;precisely why it's brought up.
Absolutely magnificent results.I have never questioned the speakers specs. 
I brought up the design to discuss the the physics of the design.
My final comments were about stuffing material within the mid enclosure; with
the question 'where does the energy go?".
It remain a very reasonable enquiry.
Do you know anything about what's inside the enclosure?
Either materials or internal design?
