MurderMat vs Dynamat, FatMat, SecondSkin and Audio Technix

Want to do a real test? Check out on AT or Alpha Damps sites at how they test theirs? maybe do a heat test... a vibration text on a 12x12 metal sheet, with a 4x4 piece of the mm, stuff like that...

this kids a moron lol agh man funny stuff right here thanks for the mils graph thats about it im prtty sure it has alot more to do with then mils cuz rattle trap extreme says its 80 mil and that shits garbage i bought some stp atlantic 80 mil and that stuff is thick as hellllllll

The only "mils" that matter are the ones that indicate the thickness of the constraining layer (foil). You can have 1,000 mils of substrate and 1mil of foil and all you're doing is mass loading. And if you wanted to do that, you can just go grab some peel n' seal or FatMat rattle trap that's $1/ft.

Glad you're pleased with the product though. It's nice to have another $6/ft deadener to choose from :rollseyes:

Wow this is a shame, We have a new company trying to break in the market and actually give some people some products, Yet every time jag opens his mouth he brings down mm with him. Even if mm is no better then everything else out there and they are something new to the market that at least looks different then the industry standard. I just know one of the requirements of winning this product was having a good attitude yet this guy is the most flammable thing on ca.com right now. Seems like every topic he is in, turns into a troll session from people here. If you dont feed the trolls they have nothing, If you really wanna help mm jag keep your mouth shut install the product take pics of it in there say "it stop my rattle issues here, here, and here" and every once and while say hey its still standing strong.

@tprj82 I understand what your saying, and I share your concern but, if you take a careful look a what I wrote and how others responded given, this
happened to a versus thread, it's not unusual for people to disagree or even feel a need to express there is more to sound deadener than what I wrote.
It's a discussion, and the thread was created for the purpose of discussion nothing more. Some people offered up some good points despite disagreeing
and others were there usual selves. One or two people straight up trolled (LIKE av83, who has a tendency to be boisterous and stalks me on caraudio.com),
but that happens a LOT on car-audio.com. You should never let people like that get to you. Don't fall for it. I like MuderMat, It's obvious, OK I think the CO.
is outstanding, I think everyone gets that, but by no means whatsoever by creating a graph out of just a little excitement for the product after an install
was it my intention to make other products look bad or even necessarily make MurderMat look the best. All I ask is that people read what I wrote carefully,
and look and see how others responded given the content, thank you.

Or use bricks. People always use this shit in the wrong application.

PS- SDS ftw

Opie,

I think maybe ur heart was in the right place when you did the graph. Unfortunately, just as Taylor pointed out, overall thickness isn't the be-all, end-all: the thickness of the constraining layer is a much better indicator of the deadening property of the product. And, as WD noted, all butyl is not designed equally, anyway.

Regardless, you're going down the long and tuff path by attempting to do this sort of comparison...plus you're chasing Don's coattails, as he has already invested far more effort and expense than most ever will in real-world testing and research.

There is a reason for saying SDS FTMFW !

Would you be willing to get samples of all these products and bake them to see at what temp the adhesive fails, or the butyl melts, or the constraining layer uncouples, etc ad nauseum? Much less weighing them, measuring the foil, doing RTA comparisons of percentage sound deadening on sheet metal?

I am guessing not.

Likely better just to regroup, and sorta follow the advice offered by tprj...

Thanks @flex that would really be something if I had samples of each of the brands products to test them out, but even if I did I realize I don't
have the experience to do it properly, aside from personal opinion. Honestly I was just kind of excited about the product. After I tore out my trunk,
I felt as if I was faced with the daunting task to install all the MurderMat properly, I had never done it before but you know what it ended up not
only being easy, but enjoyable as well. I had a little extra time on my hands, and that's when I decided to make the bar graph. I thought people
would like it. I'm sure someone out there appreciates the effort.

Here is what my research on Constraining layers yielded. I have not had that much personal experience with sound deadeners, but I thought

the 2 mil thick vinyl top layer over the 5mil BL and 8mil MDK versions of MurderMat was unique. My girlfriend who used to DJ told me it was

vinyl, otherwise I would probably not have recognized it. I felt it helped prevent a lot of cuts and tears as opposed to other sound deadeners

named who for the most part top layer is just foil. If I'm mistaken about that, im sure someone will let me know..

Your DJ girlfriend doesnt know anything about car audio applications. The butyl layer is there because it takes the energy from vibrations absorbs them and that energy turns into heat. Its then dissipated through the aluminum layer of foil. Without that butyl layer or aluminum foil it doesnt work. Thats why Peel N Seal sucks.

I never said my girlfriend knew anything about car audio-applications or anything remotely like it. I simply stated she recognized the top layer of MurderMat

was vinyl. Also I never once broke down or even remotely argued how sound deadener works. I have been studying up on sound deadener a lot lately so I

already knew that, but regardless I'd like to thank you for that explanation. This post here by audioholic seemed to help a lot, for anyone that's interested

in learning more about how sound deadener works check it out. The information is broken down on SDS site helped plenty.

my question is this jag, if you hadn't won would you have bought murdermat? would you still be promoting them the way you are? to put this lightly your swinging pretty hard.

I guess i would be wound up about winning too, but ****.

 

[CHEMMINS 10+ year member]

Wow....I'm gonna make a deadener that has a minimum 1" of butyl, and 10 gauge foil on it.....it will make it the thickest, most bestest deadener ever.
