Which kind of clay do I use on my MDF rings?

Decoupling the speaker from the door is an EXTREMELY common practice, and your acting job here doesn't mean alot to me. Must I find a list of resources that discuss the advantages of decoupling speakers? Or a list of top SQ competitors that 'decouple' their speakers?

Get real, dude. Using peal n seal for "deadening" is and EXTREMELY common practice, too. Should we all do this because everyone else does? Your argument is about as effective as using WAX as a decoupler for a driver! [why doesn't NHMC harden? //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif]

You know very well the reason to decouple a speaker, minimize interaction between the speaker and the door. I guess my follow up question to you would be, knowing that decoupling speakers is a common tactic, why are you here suggesting it is not necessary?

Your assertion that the interaction between the speaker and the door is "bad" is frivolous at best. Define the conditions. Localize the problem. Come up with an effective solution and implement it.
Maybe we should we be using water to put out a grease fire because it works in a lot of other conditions, too? //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

I like you, but sometimes you seem like you are here more to try and look smart than to actually extend any realistic information that people can use.

I sometimes wear a pair of bogus, metrosexual-looking black-framed glasses to make me look smart. Shall I post a picture and see if your theory is correct?

So if you think you have data or a theory that says otherwise, how about explaining yourself out instead of telling me to look up the modulus of elasticity of the materials being discussed?

Look up the data Linkwitz posted on his site.

Mass loading and elasticity have virtually no correlation.

They sure as hell do when constant vibration is present.
You're really not on a roll today, man. Everything ok? //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

I already suggested to use Alumilite clay which heat doesn't have much effect on. Where are your suggestions? Hold on, I'll go back and look.....

Ok, didn't find any from you. So, feel free to recommend at any time.

Yea, whenever you're ready.

Come on now, we're burning daylight here......

Just did a search for "non hardener modeling clay" as you suggested.

Your search - non-hardener modeling clay - did not match any documents.

Suggestions:

• Make sure all words are spelled correctly.
  
• Try different keywords.
  
• Try more general keywords.
  
• Try fewer keywords.

Good one.

*yawn* All that typing, and not one fact that disputes the widely accepted reasoning to decouple speakers. The best info I got from you is a vague reference to a link, that you didn't even provide.
Yes you are right, using peel n seal is common, so clearly ALL common decisions are wrong. Right? //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

You are a smart guy, that's how I know you are intentionally diverting the topic, rather than actually being this obtuse. The point was decoupling speakers is a WIDELY accepted practice, yet here you are laughing at the very notion of it, with no reasoning other than 'why would you ever do such a thing'.

Look up the data Linkwitz posted on his site.

Ah yes, the vague reference to data that you imply supports whatever it is you are trying to argue here. You know what, I took your advice.
http://www.linkwitzlab.com/links.htm

And on this page I found the link to the article on decoupling speakers. Here's a snippet:

"Earlier studies have shown that the dominant excitation is mechanical and that clear benefits can arise in reduction of cabinet colouration if this excitation mechanism is reduced or eliminated." - Andrew Jones of TAD/Pioneer per the article titled "Decoupling a midrange driver from the cabinet".

So maybe you'd like to stop being so vague now? The info you yourself brought up seems to support the idea that you DO want to decouple your speaker from its cabinet (or in this case, the door).

I already suggested to use Alumilite clay which heat doesn't have much effect on. Where are your suggestions? Hold on, I'll go back and look.....

I see I got on someone's nerves. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif I forgot, you dont like to be questioned, only told that you are right. You know the sad part? If you were to give a theory as to why you think practically everyone else in the industry is wrong about decoupling speakers, coming from you... Id listen. But instead you came here and acted like a know-it-all with all the answers but that is unwilling to share them with the rest of the class. Get over yourself. Tell us what YOUR theory is, or go stand in the corner of the class and think about what you've done.
By the way, my 'suggestion' came in the form of the information I posted on page 1, response number 1. I fail to see how you missed it.

Furthermore, my comment on 'realistic information' was based on the comment I quoted, and subsequently replied to. Not a comment on Alumilite which I did NOT quote. I thought that was pretty obvious.

You could have explained why you think the 'modulus of elasticity' is an important factor, but you didn't. You just threw out a technical term and demand I look up your reasoning.

Just did a search for "non hardener modeling clay" as you suggested.

Good one.

Where did I suggest you, or anyone, do a search for non hardening modeling clay? //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif BTW, its non hardening modeling clay, which would yield you plenty of results, were anyone to suggest looking up such a thing. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
Did you wake up on the wrong side of the bed today?

non-hardening...

sounds like something related to eD.

decouple the speaker or the baffle?

I wouldn't want clay all over my precious speakers, but on the ugly wooden baffle, then that's a whole different story //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Oh and, are you telling me that concrete is a poor mass loader since its elasticity is poor?

Decoupling the mounting ring from the door has the same effect as decoupling the speaker itself. The point is to try and isolate as much of the mechanical vibration of the speaker from the door as possible. That is why the elastic properties of a decoupling material is critical, but means little to simple mass loading situations.
