[QUOTE="Jeffdachef, post: 8671859, member: 650438"] looks like a complete waste of money, just a layer of closed cell foam on top of the aluminium backing which does absolutely nothing soundwise, you need MASS LOADED VINYL for any real acoustical barrier results which is heavy in mass and actually blocks sound, deadener and mass loaded vinyl will absolutely sh*t all over this overpriced foam gimmick purely due to physics standpoint and actual SQ builds that win nationals that require an absolutely quiet environment. As for the deadener side, What you want is a stronger butyl/aluminium backing which looks like they didn't change at all its still 80 mils which is the same as their expert roadkill, literally took their expert roadkill and slapped some cheap foam on top and marketed as something different they are trying to copy GP car audio's stfu deadener [URL="https://gpcaraudio.com/gp-stfu-v2-250mil-40-sqft-10-sheets/"]https://gpcaraudio.com/gp-stfu-v2-250mil-40-sqft-10-sheets/[/URL] all the foam does is decouple panels from rubbing against solid metal parts, you can just buy some closed cell foam from walmart and achieve the exact same results. . Knukonceptz kolossus is much thicker and proven deadener on the thread on DIYMA forums that rannked 1st in a bench deadener dyno test of 50+ kinds of deadener on the market right now.
