Eliminate increased distortion and decreased bass response caused by standing waves with one quick step–install Stinger RoadKill Speaker Standing Wave Rings. Stinger RoadKill Speaker Standing Wave Rings absorb and deflect rear energy from the back of the speaker, keeping the energy from returning and interfering with the front wave output. The easy peel and stick adhesive allows for fast, clean installation when adding these rings to speaker installs, while the egg crate acoustic foam decreases distortion and increases bass response.
