【Door Internal Diffuser Material Increase 1｜Diffusion Effect Enhancement Plan】

This is an installation where additional diffuser material is added while checking not only the rear side of the door, but the entire inside of the door—taking into account how sound reflects and spreads.

By doing it at the same time as door deadening, you can confirm the condition of the interior during the installation and apply the right materials in the right places. It’s suitable for those who want to further refine sound cohesion and how it comes through, and for those who want to pay attention to the door finishing as well—along with a speaker replacement.

Even with the same diffuser material, the result varies depending on where and how much is used. While considering the vehicle and the combination with the speakers, we’ll determine together which parts are necessary.
