What is this?
Speaker sound-absorbing cotton is installed in the speaker to absorb standing waves from the low frequency of the cabinet. After installing the sound-absorbing cotton, it will make the bass clearer and stronger. It can be used for DIY subwoofer, speaker cabinets, and interior decoration and filling of car audio systems.

What will I get?
Color: White
Size: 100x120cm/39.37"x47.24"(W*L)
Package Includes: 1 x Speaker Sound-Absorbing Cotton

Are there any advantages?
It is a sound-absorbing cotton dedicated to speakers, flame-retardant, soft, and elastic. The material is odorless. It provides effective damping with a noise reduction coefficient of NRC≥0.76, absorbing multiple harmonic generated by the speaker enclosure, enhancing bass performance, and making the bass clearer.

How to use it?
When the bass is smeared, install more sound-absorbing cotton. Otherwise, reduce cotton.

What should I notice?
After being compressed and packaged for a long time, the thickness of the sound-absorbing cotton that has just been compressed cannot immediately return to 5cm; it needs to relax and rebound naturally.
