【Increase Diffusion Material Inside the Door|A Installation to Make Speaker Sound More Natural】
In addition to the diffusion effect at the rear of the door included in the plan, we will check the inside of the door and add diffusion material where it’s needed, in the right amount and in the right place.
Rather than applying the same amount uniformly, the key is to adjust the installation area while looking at the vehicle’s structure and how the speaker sounds. This helps refine unwanted resonances inside the door and bring you closer to a condition where the speaker’s natural sound can be utilized more effectively.
This installation is suited for people who feel that “the sound sounds a bit muffled,” want “better cohesion in the bass,” or “want to further refine the finishing after replacing the speakers.” Since the most suitable installation method varies depending on the vehicle model, the speakers, and the deadening materials you combine, let’s review it together while looking at the actual vehicle.
