Fatmat good?

[Bassin Buick]

I'm looking to deaden my doors sometime soon. My buddy used fatmat but i didn't hear his doors before and after. Right now i have literally no response under 200hz in my doors even though my HPF is set at 80. LOL. So is fatmat a good value or is it kinda "you get what you pay for"??

its good for the price.. its not good compared to damplifier but i got 100^ for 180 and it went a long ways.. i got the xxx rattle trap though

Check out audio technix! Its thick as hell and the price is right. The guy owns it is running a sale to get his company kicked off. Twisted Child did a youtube vid I think today of an install he did with this stuff. I think its legit.

cool. i will look into it. I need to seal off my doors badly and prolly put some on the inside of the outer door skin too. Also i'm gonna cut and mount baffles for my selenium 6w4p's and get these jbl 5.25's outta there.

To answer your question simply, no.

In detail...it's just deadening that you get from lowes meant for roofing insulation, with a fatmat decal on it. Super thin, and does not stay stuck to the surface its on for very long. Any deadener, even duct tape will make things rattle a lot less, because all it does is provide mass to the metal surace and reduce vibrations.

SoundDeadenerShowdown isn't cheap, but they have the best customer service of ANY company I have ever dealt with for, well, anything in general! I emailed like 5 companies, eDead, Dynamat, Raam, etc. and the only one who sent me a sample of their product was SDS. And they didn't cheap out, either. They sent me a nice sized sample of every single one of their products, and paid for shipping. Communication was very fast, and the owner was a pleasure to deal with. For that reason, I feel obliged to inform you of their product. An independent user sampled SDS, Raam, eDead, and something else, and came to the same conclusions about their customer service, and they also said that SDS had the best deadener based on unbiased, multi-trial pop can drop tests. It's not definitive, but still.

Geoff and I have used FatMat btw. We didn't use much of it for long though, nor did we pit it up against any other kinds of deadener, so our opinion on it is to be taken with a grain of salt. Except for the first paragraph of this post about it, because that's more of other people's opinions than mine.

TLDR. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif J/K , i will look into a lot of brands before i choose. BTW , i seen people use that peel and seal from lowes. LOL

well i dont guess many people know hwo to apply it. I ve had it for a year in my truck and its still stuck to the roof and i have done upper 150s on a regular basis daily. and the fatmat is thin.. rattle trap is not bad

 

[Bassin Buick]

the rattletrap is what i was looking at. Looks decent. And yes proper preparation is key when applying dampening.

and another fyi... the audio technix is the EXACT same price and the rattle trap is 25% thicker 80mil>60mil //content.invisioncic.com/y282845/emoticons/boink.gif.91933e72f927f2cefc79aff02573090c.gif

ya.. i took my time.. i used a blow dryer and heated that **** up and mushed it on good with a roller. you can tell from the pic.. i havent had many problems with it. I used lots of layers on big areas liek the doors and they are solid..

SDS, do it.

Yeah dude don't cheap out, especially when your talking about your doors and trying to improve SQ. My motto is "If you don't make the time to do it right the first time you better make time to do it again." Same thing applies to cost //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Asphalt based mat like fatmat (and peel n seal) are pretty much just a mass loader which lowers the resonant freq of the panel its attached to. This does not eliminate the rattle, it would take a large amount of mass to lower a piece of sheet metal's rez freq down to subsonic levels. But it does move the freq of the rattle further away from the most sensitive freqs for the human ear... midrange. Asphalt can have adhesion problems, and requires a heat gun to apply it properly. In the many years I spent installing asphalt mat, premature adhesion problems were rare. But I definitely noticed the other problem asphalt has, drying out. When it dries out it loses mass, and it did start having adhesion problems. I said premature adhesion problems earlier because I dont consider the mat losing adhesion due to drying out being a failure of the product so much as its lifespan simply wearing out. It usually took several years before drying out became a problem, but once in a while I get a few rolls (of dynamat original mostly back then) that had clearly been sitting on a shelf too long and were already drying out and starting to crack.

Butyl mat is a mass loader which does the same as mentioned above, but with the added benefit of a visceolastic effect of absorbing *some* sound waves. Butyl rubber is also a much more inert and impervious substance than asphalt. It wont dry out (in your lifetime), and its less affected by external factors such as temperature. Butyl mats do not require, or even want, additional heat to be applied, just lay it down and roller it on. After a few years of using butyl now, Ive yet to see a single sign of adhesion loss. I dont expect to either.

Are the added benefits of butyl based mats worth the extra money? I think it is, but not everyone values things the same. What I can say is, if budget is your concern, look into the 25% coverage information from Don at sounddeadenershowdown. You may decide you need a lot less mat than you first realized, making a higher quality mat affordable.

That's great that you mention the 25% coverage idea. Buying a bunch of crappy deadener vs. A small amount of totl deadener will net you worse results. Pay $100 for 50cft of terrible deadener or pay $100 for 12.5cft of awesome deadener, and the better deadener will net you better results.

Denim, are you affiliated with SDS? Because that would explain their amazing CS //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
