Please forgive my long post:
Just to add my 2 cents, cheaper isn’t always better. There is a reason products that are sold cheaper than others. Some of it is due to using lesser quality products/materials, not paying for their own designer/engineer to design said product, using lesser quality tolerances, etc. Sometimes, a less expensive product works fine for what you need said product to do, but in my experience that is usually not the case. Nor does the most expensive product yield the best result.
Over the years, I try and find the middle ground. I still get sucked into the marketing gimmick of price and it still bites me once in awhile. I try and get quality products that won’t break me. Sometimes this means I have to wait or hold off on finishing something. In the case of the CLD, there is really no unbiased way to fully determine which actually performs the best. There are specs on some, per the manufacture’s site but there is no non profit organization that test the effectiveness of these products and provides the documentation to back them up. I maybe wrong but if there was there is no publicly provided documentation. Heck, even though there is a certain standard for amplifier ratings, certain manufactures still lie out of their teeth about how much power they provide. We should work on using common sense when it comes to some of this stuff. Uninformed consumers will continue to buy cheap products because of price and Amazon hasn’t helped that.
So from my experience, I have used Dynamat in three of my cars over the past 30+ years, showing my age here, with good results. My first car, there really wasn’t much competition, early 90’s, so it was my only option. My second car, I think some car audio manufactures were adding to their lines but it wasn’t their core business. So, how did they provide it. By going to a third party and having them do the leg work of design, production, etc. That same third party also probably sold the same product with different name to others, which is how said third party made money. Were they cheaper than Dynamat, yes but not by much, so I stuck with it. On my latest car, I used the CLD testing that was in this forum and went with the Knu Knoise Kolossus Edition CLD. Pricing was very good so I went with it, did it work, yes. It did an excellent job, however there was a small price I paid for the lower cost. It didn’t melt but stayed very pliable during the hotter months in Oklahoma. So in my trunk, where placed heavy tool bags, baseball equipment, etc, the Kno Knoise Butyl layer squeezed out and stuck to things. Is this a deal breaker, no. I opened up one of my doors a few weeks back and all the deadener in the door looked as good as the day I put it on. This product has been in my car for 4 years.
one final example, my church has bought plenty of cheap stuff over the years I have served there as the audio engineer (soundman). And in every instance, those products have been removed, didn’t work at all, or broke. Finally the past 10 years, I have gotten them to realize there is a minimum we should strive for and the results speak for themselves. Products last longer, quality of the overall audio is improved, etc. I also don’t worry if the next Sunday is going to a disaster.
So, would I use the Noico, no. I try and steer clear of the cheap stuff. I guess what I am trying to say, there is a market level for everyone, for me, it’s not the cheapest stuff. For others it is and they are fine with that. They just need to know that there is a price to pay, no pun intended, for what they buy. I have other examples, etc but I will stop here.
