【AT-AQ770 Vehicle-Mounted Sound Absorbing & Diffusion Material｜Tames Reverb from the Speaker Rear to Reduce Sound Dullness】

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

AT-AQ770 is a sound-absorbing mat that you apply to the outer panel on the rear side of the speaker. It suppresses unwanted reflections and resonances generated within the door, helping to keep the sound coming from the speaker from wrapping around and turning muddy. It’s an item for those who want to hear the speaker more clearly, especially when you’re bothered by dullness or blurring.

The material uses EPDM, known for excellent flexibility and follow-through. It conforms easily to the irregularities of the door panel and can be installed using a practical size of 200×200 mm. Another feature is that you can adjust how effectively it absorbs sound by removing the built-in control chip. Depending on the condition of your speaker and door, and your preferred sound, you can fine-tune the system—not just stick it on.

However, installation for car audio depends on where you use it and what combinations you employ. 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 content that has already been installed. If it were me, I would check the vehicle’s condition before adding any materials, and use only the necessary amount in the required areas.

At LOGON, we work with you to plan an installation method—including AT-AQ770—according to your speaker replacement or door tuning. If you’d like to hear your usual music a bit clearer rather than just louder, or if you want to bring out the speaker’s true character, please consult us. We’ll suggest a practical approach tailored to your vehicle model and current system.
