【M&M Inner Baffle MX-611＋PCD1｜High-Rigidity Aluminum Speaker Inner Baffle】

Even after replacing the speaker, you may not notice the sound change as much as you expected. In such cases, it’s worth looking not only at the speaker itself, but also at the mounting base used to secure it to the door.

M&M Inner Baffle MX-611＋PCD1 is a high-rigidity type speaker inner baffle made from solid duralumin-series aluminum. With an aluminum base machined from billet on a CNC machining center, it’s easier to firmly mount the speaker and acts as a foundation for transmitting sound to the door.

Conventional wooden baffles such as MDF or plywood may deteriorate over time due to moisture inside the door and condensation. The aluminum MX series has less concern about corrosion or decay from moisture like wood does, making it suitable for those considering inner baffles for long-term use.

Compatible vehicles include some Toyota, Nissan, Subaru, Daihatsu, and AUDI models. However, compatibility and required parts vary depending on the vehicle model and year, the shape of the factory speaker, and the speaker you plan to install. Inner baffles are not just parts you attach—it's important to consider the finished result, including your speaker combination, the condition of the door side, and how you will secure it.

At LOGON, after confirming the combination of the vehicle model and speaker, we guide you including any necessary machining and surrounding installation work. If I were doing it, I would not only address the sound direction when replacing the speaker, but also properly work on the mounting base. Let’s think together about a setup you can enjoy listening to for a long time.
