Interesting Magico news

MelBguy,

Can you say more about the damping mats you mention in your previous post? Do you know either their composition or their source?

(So Magico use 5-layer damping mats to prevent any audible ’excitement’ from the cabinet.)

Thanks in advance,

@cdk84, Magico were using Black Hole 5 or a similar product for the S5 Mk1. Here is a pic of the damping mats applied to an S5 - http://audioshark.org/attachment.php?attachmentid=10892&stc=1

I don’t know specifically which product they’re using for the S5 Mk2 as there hasn’t been any internal photos of an S5 Mk2 in the factory posted yet to my knowledge.

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.

Keith, the shape of the enclosure is first designed using SOTA Finite Element analysis modelling tools, then then ultimately formed using a proprietary polymer material.

You're right, most high end manufacturers isolate the midrange driver using either an isolated module (like Wilson) or midrange enclosure. Magico were using a midrange enclosure for the S5 Mk1 for example, though it was made of aluminium and had a no parallel surfaces. The S5 mk2's custom polymer enclosure takes it a step further and has much lower harmonic distortion.

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.
