【Original Deadening Stage 1 (Inside & Outside)｜Door Deadening for Both Sound Quality Improvement and Noise Reduction】

Original Deadening Stage 1 (Inside & Outside) is a deadening installation designed for those who want to focus on the front doors to improve how easily you can listen in the cabin and to refine the rigidity around the doors.
It’s not just about filling the service holes—by installing from both the inside and outside with intent, we create a foundation that allows the speakers to reproduce sound more naturally.

With the factory doors unchanged, vibrations and unwanted resonances tend to remain, which can sometimes make the bass sound blurred or cause you to notice sound leakage.
By reviewing and adjusting this according to the vehicle’s structure and condition, the way the sound comes together and how quiet it becomes can change significantly. Even with your usual songs, vocals become less likely to get buried and the low end can sound more composed—your overall impression of everyday music time will be quite different.

Also, this kind of installation is not something that ends with simply “sticking on materials.”
Because the finish changes depending on where and how you press it, and how far you process, at Logon we make it a priority to check the vehicle’s condition and apply the necessary work firmly where it’s needed. It’s a great match as a foundation even for those who are considering speaker replacement or upgrading their car audio.

Even if you’re new to deadening, you don’t have to think it’s difficult right away.
You’re welcome to start with questions like: “I want to make the sound easier to hear even a little,” “I’m bothered by the light resonant feel of the door,” or “I want to make a change even while keeping the factory speakers.” We’ll guide you by organizing the best approach to suit your vehicle and how you use it.

This is a menu recommended for those who want to thoroughly secure the basics, centered on the front doors.
If you’d like an installation that also includes the rear doors, you can also consult with us while we consider how you use your vehicle.
