【Sound Proofing Wave｜Adjust the gaps around the inner baffle to deliver the speaker’s sound naturally from the OEM grille】

When mounting a speaker with an inner baffle, there may be a gap left between the speaker and the door trim panel. If sound escapes through this gap or the trim panel vibrates unnecessarily, the sound from the speaker you’ve taken the time to replace may be less likely to come through in its intended direction.

Sound Proofing Wave is a deadening option designed to fill the gap between the speaker and the door trim panel. By reducing sound wraparound into the door and lowering resonance of the trim, it creates conditions that make the sound produced by the speaker easier to reach the OEM grille side.

Changes in sound aren’t determined by speaker replacement alone. By fine-tuning not only the inner baffle shape and its positional relationship with the door trim, but also the speaker’s orientation and surrounding treatments, you may find the vocal position easier to discern and the overall coherence of the sound improved. This is especially meaningful for those who want to replace the speakers while keeping the OEM grille as-is.

Because the size of the gaps and the required treatments vary depending on the vehicle model and speaker, the same approach won’t fit every car. At LOGON, we review the actual vehicle condition and recommend only the necessary work—including combinations with the inner baffle and deadening. If you’ve replaced your speakers but the sound doesn’t come out in the direction you expected, or you’re concerned about vibration in the trim panel, please feel free to consult us.
