【Add Diffuser Material Inside the Door | Inspect the Door Interior and Install Where It Fits】

In addition to the diffuser material on the rear of the door included in the plan, we add diffuser material to the necessary locations while checking the condition inside the door.

How sound comes together depends on the vehicle model, the door’s structure, and the speaker mounting condition. Rather than simply increasing the amount, we ensure the proper spread and resonance of sound inside the door by installing the right material in the right places after taking a close look at the interior.

Even when using the same material, the final result will differ depending on where and how it is installed. We perform the installation with the goal of achieving more natural, easier-to-listen-to sound, while confirming your vehicle’s condition and its compatibility with the speakers.
