【UD-K629 (16 cm) Inner Baffle for Daihatsu/Toyota Vehicles】

Even after replacing your speakers, the sound doesn’t change as much as you expected. In such cases, you’ll want to look not only at the speaker itself, but also at the mounting portion on the door.

UD-K629 (16 cm) is an inner baffle for Daihatsu/Toyota vehicles. It provides a solid foundation for securely mounting the speaker and increases the strength of the door metal panel area, making it easier for the speaker’s movement to translate into sound. With the included wave-shaped sound-deadening cushion, it also helps suppress resonance near the mounting area and the effects of sound that wraps around from the rear of the speaker—this is a part designed to refine the sound’s definition and overall presence.

If you feel that the vocals are a little too far away, the bass becomes blurry, or when you raise the volume the area around the door starts to resonate—reconsidering the inner baffle along with the speaker replacement can sometimes change how cohesive the sound is.

However, even with the same 16 cm speakers, compatibility and the necessary modifications will vary depending on the vehicle model, the shape of the factory speakers, and mounting conditions. At LOGON, we don’t just select speakers as a stand-alone item—we think together about the baffle and the door-side processing, as well as the installation method, based on the vehicle, your current system, and the direction of the sound you want to hear.

If you want to properly bring out your speakers’ performance or want to make sure the base area is well prepared when upgrading from the factory speakers, please consult us while confirming the combination of vehicle model and speakers. If I were doing it, I would finish not only the speaker itself but also the mounting portion to aim for the sound changes you’re looking for.
