Product Overview

Upgrade your car audio setup with Deaf Bonce Double Rigid, high-performance vibration damping and sound deadening material designed specifically for heavy-duty SPL competition builds and premium automotive audio installations. Engineered by Deaf Bonce to withstand extreme sound pressure levels, Double Rigid eliminates panel resonance, road noise, and body flexing caused by powerful subwoofers and high-output door speakers.   

Formulated with pure butyl caoutchouc and a polymer-enriched bituminous mastic layer, this sound deadener maximizes the Mechanical Loss Factor (MLF) to convert unwanted structural vibrations into harmless kinetic energy. Safe, non-toxic, and odorless, Deaf Bonce Double Rigid provides the ultimate acoustic foundation for high-power sound systems.   

Key Features

• Maximum Vibration Absorption: High Mechanical Loss Factor (MLF) minimizes metal panel flex and structural vibration caused by intense SPL bass.

• Pure Butyl Caoutchouc Compound: Premium-grade butyl formulation guarantees long-lasting flexibility, superior adhesion, and structural longevity.

• Polymer-Enriched Bituminous Layer: Reinforced multi-layer construction delivers extreme rigidity to treat problem areas like door panels, trunks, roofs, and floors.

• Eco-Friendly & Safe: 100% free from harmful chemicals or toxic emissions; non-hazardous and completely odorless inside the cabin.   

• Enhanced Acoustic Clarity: Reduces exterior road noise, tire hum, and suspension rattle to let your car audio system play cleaner, louder, and without resonance.
