Dynamat 11800 DynaXorb Speaker Kit 2 Pieces, Size: 6" x 6"

Back wave distortion, a common problem with every speaker, occurs when your speaker sends the same sound out the back as it does out the front! If this rear sound wave energy is allowed to bounce back and return to the speaker, it interferes with the speaker's ability to operate properly causing back-wave speaker distortion.
Dynamat DynaXorb absorbs, diffuses and attenuates the sonic energy directed towards it using Sonic Stealth Technology. Removing back-wave interference from the speaker allows every speaker to produce the full quality potential it was designed for, and delivers all the sound you paid for!
