no it doesnt harden or retain moisture. as for heat resistance i havent been able to find an exact number regarding whether or not itll stand up to a ny summer.
im just not sure if using it against the back of the speaker is a good idea in case it oxidizes??
Heres some stuff I did today. Did about 2/2.5 layers. Still have plenty more eDv1. I'm applying it with a blowdryer and really sticking the edges on so hopefully I won't have to deal with it coming off.
****Also has anyone ever tried using Great Stuf foam in the doors? I used some in my left door... I'm thinking of being real careful and filling up the very innermost part closest to the engine that I can't really reach with deadener. Have to watch out for the window track and also not to block the drains for water. Anyone think it's a good/bad idea? Should I not bother?
I'm using the stuff for windows that WILL NOT expand to the point of bending the door frame.
What type of non-hardening modeling clay are you guys using? Went to the crafts store today and they had Roma Plastina, but only #1 and #2...are these okay to use?
This may have been asked in the previous 21 pages, but is there anything that you can do to the egg carton foam to make it water resistant. cover it with a plastic bag and melt it on (with a lighter) might be an idea? What do yall think?
Would extra pads of ensolite behind the speaker be comparable to the egg carton foam for breaking up the waves?
Ensolite is a brand of closed cell foam which is often used for its waterproof qualities (sports equipment, industrial apps where there is water, etc). There are many types of Ensolite and many more types of CC foam.
Typically egg carton foam is open cell, but you have to check and see for sure which one you have. Technically, it should be more absorptive of sound because of its material properties. The draw back is that it can also absorb water, too.
If you want to defract or "break up" sound waves you need a blocker or a barrier. This is where products like Deflex pads come in handy. They are resonably good (depends on frequency band) at "scattering" sound waves, but not so good at absorbing them. They are almost always made out of low durometer rubber or silicone and have a convoluted surface to "soften" the blow of a rear wave from a close distance.
Does this happend to work for just basic installs or is this for speakers that will be used for midbass... etc.. etc...
I would look to install bunch of infinity 6012i to replace the stockys nothing big... but by doing thsi will this improve anything?
well i look to change the speakers anyways i guess ill throw the remaning i have left around the speaker and work outwards... by dynamating the door (i have that elemental design one forget the name) but yea will it also help keep some of the road noise out aswell??
i got the .75mm thick one its a pretty thick pieice and i ahve enough for maybe about 65% of the entire door n alot of it i mite not need because of the holes in the door what wil i fill thoes with not messing with the window from going up and down?
Nice Article. I went for Dynamat.. bit costly..but, I never regret.

why do you guys put 2 or 3 layers of deaden? i never did any, but soon when it stops snowing here in PA
