Important: door damping

When replacing the speakers we also recommend damping the doors. Applying damping materials will significantly improve not only the bass component and the sound of the mid-woofer, but will also prevent vibrations and resonances in the door area that negatively affect the final sound. You can read how to damp the doors in our article, which provides a detailed procedure for applying damping materials and all related benefits. For damping two doors we recommend purchasing the following damping materials:

• 8 pcs Comfortmat Ghost
• 2 pcs Comfortmat Tsunami (for one door 1/2 sheet is enough)
