【AT-AQ449 Duct Damper｜Deadening Material to Enhance Sound Absorption】

This duct damper is used in areas where you’re concerned about sound reflections and “leakage,” such as ducts around the speakers.

AT-AQ449 uses profile processing with height variations. It is designed to increase sound absorption while suppressing sound reflections. It’s a material suited for those who want to address even the small details around the speakers, or for anyone who wants to fine-tune the deadening results a step further.

Since the back side uses a powerful adhesive, it adheres firmly even after installation, and long-term use can be expected. Even parts that may look like they’re “just stuck on” can produce different finishes depending on where they’re applied and the combination with surrounding components.

At LOGON, we consider where and how to apply it while checking the vehicle model, the condition of the speakers, and the deadening already installed. It’s important not to use the same method on every vehicle, but to apply it appropriately to the parts that need it.

If you’d like to improve the cohesion of the sound a bit more, or if you want to finish the details together with speaker replacement and deadening, please consult with us while we review your vehicle’s condition.
