【PCD1 Multi-Pitch Aluminum Inner Baffle｜Firmly Set the Foundation for Speaker Mounting】

When you’re considering replacing your speakers, it’s not only the speaker itself that matters—the way you secure it to the door is also an important factor that affects how cohesive the sound feels. PCD1 is a multi-pitch type inner baffle made from 8mm-thick solid aluminum.

The material is aluminum. Each piece is machined from solid stock using a CNC machining center, and then finished with gold anodizing for corrosion protection. It’s a part that’s easy to plan for if you want to create a solid foundation, or if you find yourself unsure about installation methods with wooden baffles alone.

By combining it with an inner baffle base made from plywood or similar materials, you can disperse resonance frequencies while changing the material and thickness. You can also stack two or three PCD1 units, or combine PCD1 with commercially available inner baffles.

However, the exact combinations that work best will vary depending on the vehicle model, speaker size, and the space inside the door. It’s important not just to use an aluminum baffle, but to carefully confirm mounting strength, the speaker position, and potential interference with the door trim before finalizing the installation.

At LOGON, we consider the required thickness and how to build the base together while looking at the combination of your vehicle and speakers. If you want to be particular about the foundation when replacing your speakers, don’t judge everything based on parts alone—please consult us and match it to your actual vehicle.
