- 【ITCH-FREE & FLAME RETARDANT】 Upgrade your audio system comfortably and with peace of mind. Unlike traditional fiberglass, our premium polyester acoustic stuffing is strictly flame-retardant, completely skin-friendly, and odorless. You can easily handle, tear, or cut the material bare-handed during your DIY speaker repair without irritation.
- 【EFFICIENT PACKAGING & OPTIMAL DENSITY】 Originally sized at 110cm x 50cm x 5cm (pre-compression) to provide more coverage than standard 100cm sheets. To optimize shipping volume, this item arrives tightly shrink-wrapped. Note: The material will expand upon opening but may not 100% recover its exact pre-compressed dimensions. This slight condensation actually increases the fiber density, resulting in superior acoustic dampening and tighter bass control without sacrificing usable coverage.
- 【ELIMINATE BOOMY CABINET RESONANCE】 Maximize your acoustic performance. When applied to the interior walls of your speaker box, this high-density polyfill efficiently reduces internal standing waves and dampens unwanted resonance, delivering a tighter, cleaner, and punchier low-end bass.
- 【VERSATILE MULTI-SCENE DAMPENING】 Engineered for diverse audio environments. Whether you are lining compact bookshelf speakers, building a massive home theater subwoofer enclosure, or upgrading your car audio door panels to isolate sound, this tunable acoustic tool provides consistent noise reduction.
- 【EFFORTLESS CUSTOM INSTALLATION】 Designed for immediate use once unpacked. The soft and flexible polyester matrix allows you to easily shape the insulation pad to fit perfectly into tight corners, braces, and irregular spaces inside any sealed or ported box. Simply cut to your desired volume and insert.
