Hi Sumotan,

Can you discuss the damping compound trick you did. I would be interested in trying it out myself.

I damped the surround as per Troels way. Off course the secret is the compound.
Not sure if you can get it. Im into ship interior design & construction. It is a water base latex
compound that we use for flooring work. If you've got friends in shipbuilding I'll be glad to tell you what to ask for. It's white & milky when applied it's blueish but dry transparent.
Surprisingly effective.

Cool - that sounds like some of the speaker "glues" sold

Hi Freddi
FYi more important is the damping compound.

Don't know any but who knows in these days you can buy anything of the internet.

I read Troels article before. And there is a Thread here in DIY audio discussing it.

Visaton LTS 50 is pretty good and can be easily purchased. It improves the highs a lot. cuts down a lot of noise.

The reason is be cause this compound comes in gallon packaging only Oon
All that's needed in so so little to paint the surrounds.
Btw how can I post music clip here. I can record some & you guys be the judge.

 

[diyiggy]

Remember guys Audax and the aerogel ?

 

[diyiggy]

Not clear to me if such coumpunds full the nasty notch or if it works like a pass band notch itself ???

 

[sumotan]

Yes I have a pair of Audax 130zo aerogel drivers Diyiggy.
Will find how to attach some musics clips. For sure the shout/peak
is gone with no listening fatigue. Will continue to test some damping on the cone & dust cap but have to find a way to be reversible.

 

[diyiggy]

In the Audax it's made of an acrylic coumpund too !


Your 13 Audax is an excellent driver, why nt try something with it ? No efficienty enough for your tastes ? That's true their 10 cm is even better though !

 

[sumotan]

Audax is aerogel something that's lighter then air.
Have collected some drivers over the years Diyiggy.
Anyway for what the 3fe22 does, its quite mind boggling.
It plays loud too it should sound pretty good once loaded.
Im listening to it in free space. Let's see how far I can go with this damping to try & improve the sound further.

Makes me think about what Planet10 is using himelf but can be found in tools stores or internet, it's in the thread.

 

[sumotan]

For me it's just a flash idea as I got a huge bottle at home & knowing its properties I thought that I should give it a try & surprise surprise Lol

 

[diyiggy]

I don't think it's lighter than air of course and btw it's too much tacky to be light. I think they sprayed it... perhaps that's the aero word into it !


Too bad you don't measure your drivers before and after...


In the SS 10F/84 : its a wooven poly material with a very thin very aero coatings , I ask myself if someone even tried to tame what's above 1.5 k hz with such coatings ?

 

[sumotan]

Well if you do a search on aerogel it does say its lighter then air, think i saw something about it in youtube once

 

[diyiggy]

marketing. Or it had called that hydrogengel !

 

[sumotan]

Who knows but it quite a unique driver though.
There's no dust cap & has a rubber phase plug instead.

 

[diyiggy]

not sure one made a better material than Audax, but who knows !I can remember it was good for the mids and low trebles but their areogel paper kevlar was not superior to their paper in the bass with some 21cm ! Well maybe due to others parameters (T&S, motors)!

 

[oon_the_kid]

Hi,

Aerogel is not exactly lighter than air but about the same. It is actually similar to styrofoam which is sctually plastic filled with air bubbles. But instead of polystyrene they are using silica otherwise know as glass... So it is just glass full of air bubbles...

Oon

 

[diyiggy]

didn't know that glass was as light as air !


Yep that's the receip. I'm wonder how they do and apply it on their cones ?


Any news about the ScanSpeak 10F 8 ohms ? I have one, but dispear to use it due to its low max spl and the difficulty to horn it ! An D'Apolitto could do it a la Kef 104/2 or Proac D 3.5... but not sure I want to buy 2 more !
