er, absorption that is...

Aerogel

Amazing stuff! You could use it to cocoon your entire passenger cabin 1" thick and it probably wouldn't weigh 5 lbs. You could possibly even use it on windows. Forget about hot summer days, it's one of the best heat insulators known to man. It also has amazing acoustic absorption properties.

This stuff is absolutely amazing! The downside is price and the fact that it isn't flexible.

I figure you could do an entire car for about $200k.

55x55cm for 32 British pounds = 52.0736 U.S. dollars!

i wonder how it holds up to high frequency vibrations and can you wrap it in foil
and butyl.

I actually found a gel-like product many moons ago and posted it on this site. I'll see if I can find what it was. Oh yes, this site:

Come to think of it, Aerogel might make a great cone material. It's virtually inert and would not color sound in anyway. It doesn't resonate, it doesn't deform, and it doesn't heat up. It's also one of the stiffest materials on Earth for its weight.

Someone out there make an Aerogel cone for a Scanspeak motor!!!!

Seriously, would this not be the perfect cone material?

Assuming it has all the properties you say, it might be worth trying. Those would probably be expense drivers. Someone contact Critical Mass quick!

Aero"gel" is a bit of a misnomer. It's stiff and can shatter like glass. It's not spongy like a true gel in any way. They pull the liquid out of a gel and replace it with gas to make Aerogel.

Here ya go :

Audax HM170Z18 6.5" Aerogel Cone from Madisound

Not the same "aerogel" tho sorry

Awww Schnapazoids!

:biggrinflip::faint::bowdown:

Wait, that's an aerogel 'treated' paper cone. :cwm13:

Yeah, I would like to see a true Aerogel cone.

Sounds a lot like Focal's W cone...

But what do I know, I still prefer paper to everything else

I'd expect that a cone material that does not conduct heat well would be a negative not a plus. It wouldn't take away as much heat from the coil and from the inside of an enclosure.
