TroyStudio Speaker Acoustic Insulation Cotton Filler, 31.5" x 19.5" Subwoofer Polyfill Stuffing Dampening Standing Waves, No-shed Lint Lining Foam for DIY Audio Projects, Car & Ceiling Speaker Box

Brand: TroyStudio

Features:

• 【SPECIFICATION】: The package comes with 2pcs of speaker stand dampening cotton for efficient acoustic treatment. They are constructed from a composite of non-woven fabric and polyester fiber. Dimensions per piece: 31.5"x19.5"x1". Total coverage for both pieces: 8.62 ft². Total weight: 1 lb. Non-compressed packaging ensures fluffy, ready-to-use materials upon arrival
• 【SUPERB SOUND PERFORMANCE】: This hifi speaker enclosure foam combines a wave-patterned non-woven fabric surface with tightly bonded polyester fiber interior using a stamping process. These materials provide exceptional sound absorption across broadband frequencies. The multi-layered design significantly filters subwoofer standing waves, reduces resonance, and eliminates unwanted noise - delivering rich bass, clear mids, and crisp highs
• 【LINE FOR CLARITY, STUFF FOR BASS, NO-SHED DESIGN】: Our speaker cabinet insulation polyfill offers versatile use for dampening excessive frequencies for superior listening. For mid-high frequency clarity: Line speaker boxes in Hi-Fi systems and studio monitors. For improved bass response: Stuff subwoofer cavities to reduce standing waves. The non-woven fabric surface resists fiber shedding, while the layered construction ensures lasting stability and extends equipment lifespan
• 【WIDELY COMPATIBLE, SAFE, DURABLE】: Compatible with subwoofers, car speakers, ceiling speakers, studio monitors, floor-standing speakers, and Hi-Fi speakers, this soundproof audio stuffing is perfect for versatile audio projects. Made from 100% polyester fiber, it is eco-friendly, odorless, formaldehyde-free, and safe for skin contact. This speaker filling foam is also B1 flame retardant and moisture-resistant (water absorption rate: 0.4%), ensuring long-term safety and reliability
• 【TWO SIMPLE INSTALLATION OPTIONS】: Choose the method that suits your needs: 1. Cavity Stuffing: Fill the speaker cavity directly with the folded acoustic filler. For best results, fill 50%-80% of the enclosure's volume, adjusting as needed for your listening preference; 2. Interior Lining: Cut to fit your desired shape. Use electrical tape or hot glue for a secure, residue-free attachment. Note: double-sided tape doesn't work well for this product
