SOOMJ 20mmThick self-Adhesive Sound Proof Padding Soundproofing Foam Acoustic Eggcrate Design Car Heatproof Foam Deadener

Using this acoustic foam was so easy on my speaker project. No messing with glue , just peel and stick. Speakers sound great!

Incredible material unlike anything I have ever seen or touched applied it to my Klipsch R28F speakers behind the tweeter and mid-range speakers just on the rear inner side of the speaker but not on the inner sides just the rear and omg what a difference in detail and resolution. the speakers have the same signature but detail and smoothness and clarity. This material feels and looks like NASA issue. Also applied it the rear of the tweeters as well. All that smuck is gone just clarity and depth. Panels were cut 8X16 I first cut a 16 by 16 then cut that in half. When you cut use a straight edge utility knife on the paper side. Press the knife though to the cutting board. make sure you use a new blade for a smooth clean cut.Start at the very top of the inside of the speaker and as you go pull the paper along.

I am an engineer and I used this material for noise insulation and soundproofing in the doors of my car when I installed an advanced audio system. I have used several types of materials for the correct acoustic design of car doors. I used this material one for the door cards. And under this material there is another layer for vibration insulation.

I lined the engine space in my inboard boat. Noticeably quieter now. Adhesive did not stick to other foam, had to use some spray glue.

This is a very high quality product and a good value for the money. I used it to replace my 20-year-old rotting sound deadener mat on my boat's engine hatch. The new material is fairly thick, has a good backing layer and feels dense. I used 3M 90 contact spray adhesive to attach and it seems to have a solid, tight grip. Engine noise is now reduced. Would buy again.

Easy to use and cut to size for speaker cabinet damping

Product adhesive let's go in hot temperatures and super cold temperatures. I had it in the trunk cutting out the droning noise it worked when it was in place but the adhesive did not last on metal

even though it is thin it is very densed and blocks the noise. price, however, is way too high considering the fact it is made from recycled reused thrown away material
