Description
Onkyo Sound Damping Replica
The Onkyo is a premium, high-density car soundproofing and vibration-damping sheet designed by Onkyo Car Audio to eliminate cabin rattle and block out exterior road noise. It is widely used by car audio enthusiasts to minimize panel vibrations, isolate metal surfaces, and optimize the sound stage inside vehicles.
Material Composition:
It is engineered from a high-grade, specially formulated butyl rubber compound. Unlike cheaper alternatives, it contains absolutely no asphalt, ensuring it remains completely odorless and safe under intense sunlight.
Aluminum Shielding:
The outer layer features a specialized, corrosion-resistant dark navy aluminum foil. This gives the sheet both structural stiffness to kill low-frequency vibrations and flexibility to mold around complex body lines.
Physical Dimensions:
Each individual sheet measures 820 mm × 460 mm and carries a heavy-duty thickness of 3.0 mm
Key Benefits & Functions
Vibration Dampening:
Effectively absorbs energy from the car’s flexing sheet metal, stopping door and trunk panel rattles caused by heavy subwoofers.
Noise Isolation:
Targets low-frequency acoustics, drastically cutting down on annoying tyre hum, exhaust drone, and engine bay cabin noise.
Thermal Insulation:
Blocks external heat transference, allowing your car’s air conditioning system to cool down the cabin quicker and hold its temperature longer.
Application Areas
The X-DP350 can be trimmed cleanly with a utility knife and rolled onto multiple metal surfaces across your vehicle
- Doors & Door Panels: Resolves localized speaker vibrations and sharp wind noise.
- Trunk / Boot Space: Eliminates license plate or exhaust rattle triggered by deep sub-bass frequencies.
- Floor & Cabin Firewalls: Stops structural road and transmission noise vibrating through the chassis.
- Under-Bonnet / Hood: Suppresses raw engine clicks and blocks heat from ruining your exterior paint finish.
