【Inner Baffle for Toyota: UD-K628 (16cm/17cm)】

Even after replacing your factory speakers, if the sound doesn’t change as much as you expected, it’s important to reconsider not only the speaker itself, but also the mounting portion in the door.

UD-K628 (16cm/17cm) is an inner baffle designed to install 16cm/17cm speakers in Toyota vehicles. By securely fixing the speaker and increasing the strength of the door sheet metal area, it helps suppress sound leakage and unwanted resonance—making it easier to bring out the speaker’s true potential.

The included wave-shaped sound-deadening cushion is designed to reduce sound wraparound and interference coming from the rear of the speaker. This helps vocals’ contours and the fine details of instruments blend more naturally, so your usual music can sound a little different. It’s also suitable for those who want the sound to be easier to listen to at everyday volume levels—not only when you turn it up.

An inner baffle is not a part that will always produce the same result just by installing it. The final outcome varies depending on the vehicle model and compatibility with the speaker, the condition on the door side, and even the mounting method. At LOGON, we review combinations with speaker replacement and deadening as well, and we整理 together which areas are worth investing in.

If you want to “replace the factory speakers first” or “make better use of your current speakers,” please consult us while checking the combination of your vehicle model and speakers. If it were me, I wouldn’t think about the speaker unit and the mounting portion separately—I would review them together from the start.
