Hushmat Wave Breaker Backwave Deflecting Pads 8"x8" Pair

The HushMat Wave Breaker sound deflecting pads are designed to eliminate the back wave created from your car's speakers. Speakers create sound by simply moving air at specific frequencies. You are able to see speakers move the air when you see the mid-range cone of your speaker move when it is playing music. As the speaker creates sound going toward you, it also creates sound going backwards. This sound travels backwards and then typically bounces off the surface behind the speaker. When the waves hit that surface they then bounce back going toward to front of the speaker and you the listener. When the back wave bounces off the hard surface, it does not stay the same, but rather inverts. Since, sound travels both above and below 0 it actually cancels the sound the speaker is making. For example, if that sound wave hits the surface at 1, it will bounce back at -1, thus being the inverse or opposite of the sound that first struck it and a net of 0 (1 + (-1)=0). When back wave travels back toward you, it is creating distortion and you are losing sound quality. These HushMat wave breaker pads absorb that back wave so that you can more crisp, clear highs and more defined mid-range sound. The sound difference is quite remarkable and you will definitely hear the difference.
