Product Details

Sonic Barrier 1-1/4" 3-Layer Acoustic Sound Damping Material with PSA 18 x 24"
The Sonic Barrier 1-1/4" 3-layer composite damping material is a premium acoustic absorption and barrier material. It uses the three layers to achieve excellent reduction of sound energy from the inside of the enclosure to the cabinet walls. An exclusive embossed surface finish helps to trap the acoustic energy into a 1" acoustic foam where it is converted to low-level heat. A 1/4" foam layer covered with 1 lb. limp copolymer vinyl barrier separates the absorptive layer from the cabinet walls. A very aggressive pressure sensitive adhesive provides easy and permanent installation onto any surface. The 1-1/4" overall thickness provides the maximum acoustic absorption properties for the highest performance. It is excellent for use in any loudspeaker cabinet, and is perfect for use in most ported systems. The 1" foam layer will act as a conventional high-performance acoustic foam, and effectively absorb reflections from inside the cabinet. This will result a cleaner midrange and midbass, and can increase apparent enclosure volume. At the same time, the heavyweight vinyl barrier and 1/4" isolation foam will prevent the acoustic energy from reaching and exciting the cabinet walls. This material presents an excellent opportunity to improve the performance of any high-end loudspeaker system. Sold in 18" x 24" Sheets.

Sonic Barrier 1-1/4" 3-Layer Acoustic Sound Damping Material with PSA 18 x 24"
Sonic Barrier 1-1/4" 3-Layer Acoustic Sound Damping Material with PSA 18 x 24" is rated 3.5556 out of 5 by 9.
Rated 5 out of 5 by from Heavy thick stuff!I used what I had leftover after putting sum inside my car doors to line the interior of my speaker cabinets at home. they didnt come with anything in them.. not even poly fill... so what I had left of the 3 layer + a sheet of the 1" thick stuff is covering the top. bottom, sides and back of the cabinets.. I can DEF hear an improvement in the midbass response... much more punchy. This 3 layer stuff was alot heavier than I was expecting btw... very sticky adhesive tho... should stay up without a problem... and the thicker the foam.. the lower the Fq it can absorb. good stuff

Rated 5 out of 5 by from Great dampening!This product works very well. I know people think the cost is high, but it's 4 and a half pouds of really nice acoustic foam. I would be happy if it didn't cost as much, of course, but it's not crazy expensive as some people claim. I would give it a fair price to performance ratio. I have used this and the 3/4" version, and both have been great products.

Rated 4 out of 5 by from It's OKI used this on the back panel of my Fender Rumble 75 Bass combo, along with 1/2" Sonic Barrier on the side panels. Lining my bass combo with Sonic Barrier was just what I needed. It tightened up the bottom end and added both clarity and definition. Great punch was realized in the low mids along with a silky smooth transition throughout the mid-range; upper mids and into the low highs. Perfect for small bass combo applications. I would reccomend the 1" Sonic Barrier over the 1 & 1/4" composit as the additional layer is quite simply unnecessary. I like Sonic Barrier. It's Good. :)

Rated 4 out of 5 by from Excellent when used wiselyFor best results, place this material on the top, bottom, and rear wall of the cabinet. The side walls, which are typically a large portion of the total interior surface area, can be lined with the thinner, cheaper version of this material or something else entirely. Just for insurance, I augment the adhesive with a generous dose of 3M Super 77.Used with just the right amount of Acousta-Stuff, your cabinet will allow your driver of choice to reach its full potential. Used where it will make the most difference, the price is justified.

Rated 3 out of 5 by from Excellent Performance -- Absurd CostFirst let me say that this high-tech "Sonic Barrier" damping material actually does what it claims to do: its sonic performance as a damping material is excellent. When applied properly to the inside walls of a typical speaker cabinet, you can rest assured that it will eliminate most of your concerns regarding cabinet resonances and standing waves. That is not in dispute. This stuff works, for sure.But as others have noted, the real issue with these types of multi-layered damping materials is their cost. In subjective listening tests, in which we compared Sonic Barrier to several more conventional cabinet damping materials (acoustic fiberglass, open-celled acoustic foam, "egg crate" textured foam, "Acousti-Stuff" Dacron fiberfill, lamb's wool, etc.), neither myself nor my friends were able to discern any audible differences whatsoever. In each case, when the material in question was PROPERLY applied to the interior of the cabinet, the audible results were more or less the same. They all worked great.I suppose the main advantage of using Sonic Barrier is that it is very easy to work with. Just cut it to the correct size and shape using a large pair of scissors or a utility knife, and then peel-and-press it into position inside your enclosure. It's a no-brainer and the results are usually excellent.So it all comes down to whether or not you feel that Sonic Barrier's ease of use justifies its rather exorbitant price tag... and I will admit that sometimes, the answer to that question is "yes."

Sonic Barrier 1-1/4" 3-Layer Acoustic Sound Damping Material with PSA 18 x 24"

Hi, I have a pair of Pioneer CS-77's that I've recapped. They sound great, but I've been told replacing the old fabric cabinet dampening on the inside walls with Blackhole 5 would make some huge improvements. Sonic Barrier is cheaper. Do you recommend?

Asked by:

Which side of this foam is closer to the driver (speaker) when applied?

Asked by: Maxell
In the picture, he top is away from the wall and the bottom has the peal and stick adhesive applied to it.

Should the volume of this material be subtracted from the total box volume?

Asked by: nahles
nope!, subtract port area,brace area,speaker volume but not stuffing and don't over stuff box
