AT-AQ770 Vehicle-Mount Acoustic Absorber & Diffuser｜Tuning the Reflections Behind the Speaker to Reduce Sound Muddiness

When the sound from your door speakers seems a bit muffled, the vocals turn blurry, or the bass doesn’t feel clean, it’s worth looking not only at the speaker unit itself but also at the reflections and resonances inside the door behind the speaker.

AT-AQ770 is an acoustic mat designed to be applied to the outer panel behind the speaker. It suppresses unwanted reflections and resonances generated inside the door, helping to prevent the sound from the speaker from wrapping around and becoming cloudy. It’s an item for those who want to hear the speaker sound more clearly when you’re concerned about muddiness or blurriness.

The material uses EPDM, which offers excellent flexibility and follow-through. It easily conforms to the uneven surfaces of the door panel, and can be installed using the practical 200×200 mm size. Another feature is that you can adjust the level of acoustic absorption by removing the built-in control chip. Depending on the condition of the speaker and door, and your preferred sound, you can fine-tune the setup rather than simply sticking it on.

That said, installation of a car audio system depends on where you apply it and how you combine it with other materials. Even with the same AT-AQ770, the results will vary depending on the vehicle model and door structure, the type of speaker, and the deadening already installed. If it were me, I would check the condition of the vehicle before adding materials, and use only the necessary amount in the necessary locations.

At LOGON, we work with you to consider an installation approach—including the AT-AQ770—based on your speaker replacement or door tuning plans. If you’d like to hear your usual music a bit clearer rather than just louder, or if you want to bring out the true character of your speakers, please feel free to consult us. We’ll guide you with a practical, no-stress approach tailored to your vehicle model and current system.
