【Brass-Copper Plywood Coated Inner Baffle｜Log-on Original】

If you’re replacing your speakers, you’ll want to pay attention to the foundation that produces the sound as well. The brass-copper plywood coated inner baffle is a Log-on original part designed to firmly support the speakers and help achieve a more cohesive sound by suppressing unwanted vibrations.

By leveraging the rigidity of the material, it makes it easier to bring out vocal clarity and the amount of sonic information. In addition, a water-resistance test showed no signs of expansion even after soaking it in a bucket for more than a week—making it a finish that’s easy to use even inside doors, where moisture and water are likely to be an issue.

Of course, simply installing it won’t produce the same sound every time. Choosing the right option and carrying out proper installation according to the vehicle model, speaker, and the condition of the door is essential. If I were doing it, I would make sure to properly refine the foundation along with the speaker replacement.
