BackBoxx BackStopp Acoustic Insert

Dampen Sound Passing Through Walls

Reduce sound distortion and prevent sound from passing through your walls with the BackStopp Acoustic Insert. This sound absorbing foam absorbs excess sound from reverberating through your speaker and walls, cleaning up the in-room audio and diluting sound waves from reaching the next room over. The BackStopp Acoustic Insert works with both in-wall and in-ceiling speakers and provides insulation from exterior elements and temperatures.

• Sound absorbing foam absorbs soundwaves to reduce audio distortion and sound transmitting through walls
• Compatible with all open-back drivers and many in-wall and in-ceiling speakers
• Balances mid-range audio responses and tightens sound cavity acoustics

Place the Backstopp Acoustic Insert inside your BackBoxx housing before installing your speaker. The Acoustic Insert can be trimmed to perfectly fit inside your BackBoxx housing. When you are satisfied with the Insert's size, remove the adhesive backing sheet and adhere to the BackBoxx.
