CCeCCe Speaker Absorbing Polyester Fiber 100x50x5CM Sound Absorber Acoustic Insulation Material Subwoofer Damping HiFi DIY Repair Audio Interior Replacement

As advertised

I had trouble finding any sound insulation for speakers/subwoofers, but took the chance on this product and I'm gald that I did! I built 2 replica SVS PB-3000 subwoofers in 2024(see my build vids on YouTube), and used about 4 packs of this material, and the results were great!

Used behind my speakers in the dashboard & the overhead soundbar. Makes a big difference in the sound quality.

Ask Rufus, or search if you don't know exactly how to install.

Did a great job sound deadening for new speakers

Muy bueno

Use this product you feel one of my speaker boxes for a pair of 10 inch subwoofers worked flawlessly ‼️💯

While this poly padding was easy to cut to shape and works as intended, it really is just poly padding that could be bought at any sewing material type store. Expensive for what it is. I used two of these sheets because of the small size sheet to line the inside on a n old Klipsch home theater subwoofer that I am rebuilding with a replacement Skar DDX-12 speaker and BASH 500 W plate amplifier. I used 3M spray adhesive and that works well with this stuff.
