SOUNDWAVE EDGE
The SQL Soundwave Edge is a versatile speaker foam baffle and sound seal kit designed to fit and seal car speakers up to 10 inches in diameter, including 4×6, 5×7, 6×9, 6.5-inch, and other popular speaker sizes.
Engineered to improve car audio performance, SQL Soundwave Edge creates a loss-free acoustic barrier between your door speaker and the vehicle’s interior door panel. This directs more sound into the cabin instead of allowing it to escape into the door cavity, resulting in improved midbass response, clearer vocals, and better overall sound quality.
The included closed-cell foam strips can be trimmed to create custom seals throughout your car audio installation. They’re ideal for sealing speaker mounting surfaces, door panels, amplifier racks, and other areas where eliminating air leaks improves acoustic performance.
Made from high-density closed-cell rubberized foam, SQL Soundwave Edge is water-resistant, durable, and resistant to moisture, making it ideal for automotive environments. Each strip features premium 3M adhesive backing for fast, secure installation.
