【AT-AQ350 Damping Material｜Deadening & Materials for Tuning In-Cabin Sound Without Replacing Speakers】

You don’t need to replace your car speakers, but you’re bothered by muffled sound or extra resonance from the doors. In such cases, damping material that suppresses vibration around the speaker and inside the door is worth considering.

AT-AQ350 is a damping material made by combining butyl rubber with a tough, tear-resistant aluminum glass-cloth sheet. While the flexible butyl rubber conforms to the installation surface, it suppresses unwanted vibrations such as those inside the door. By reducing the way sound from the speaker vibrates the door’s steel panel and escapes, you may notice changes in how well the sound comes together and in the ease of hearing bass.

The key point is that you can improve and balance the sound through vibration countermeasures on the vehicle side, even without replacing the speaker unit. It’s also suitable for those who want to make use of the factory speakers or for those who want to review the sound foundation while keeping costs down.

It is designed to deliver performance even in hot and cold environments, making it easier to reduce seasonal variations in damping characteristics. Since the results vary depending on where and how widely you apply it, it’s important not only to stick it on, but to use it while considering the vehicle’s condition and compatibility with the speakers.

At LOGON, we review the vehicle model, the condition of the factory audio, and your sound concerns, and we think together about the necessary application area. Since deadening results vary depending on the installation method, please consult us about a reasonable improvement plan—including, if needed, speaker replacement—while we first let you listen to your current sound.
