Important door damping

As part of the speaker replacement, we also recommend soundproofing the doors. Applying damping materials will significantly improve not only the bass component and the sound of the midbass speaker, but will also prevent vibrations and resonances in the door area that negatively affect the resulting sound. You can read how to soundproof the doors in our article, which describes the detailed procedure for applying damping materials and all related benefits. For soundproofing two doors we recommend purchasing the following damping materials:

• 8 pcs Comfortmat Ghost
• 2 pcs Comfortmat Tsunami (one door requires 1/2 sheet)
