- [PERFECT BASS TUNING] The high-density acoustic foam effectively reduces standing waves and port turbulence while maintaining optimal bass response. Ideal for audiophiles seeking to eliminate bass and wind noise without sacrificing low-end performance. Works with home theaters, car audio systems, and PA/DJ setups.
- [PRECISE FIT GUARANTEE] Measuring 90mm diameter x 80mm height, these sponges are designed to fit snugly when sized 5mm larger than your port's inner diameter. The compression-fit design ensures secure installation without adhesives. Suitable for most bookshelf, floor-standing, and subwoofer speaker ports.
- [ACOUSTIC CONTROL] Quickly transform your speaker's bass character from deep extension to tight . Partial insertion reduces port noise while full insertion converts ported designs to sealed-enclosure performance. Perfect for room placement near walls or corners.
- [REVERSIBLE EXPERIMENTATION] Unlike permanent modifications, these sponges allow endless sound tuning possibilities. Easily test different insertion depths to find your perfect bass balance. Remove completely when you want to restore original speaker performance instantly.
- [MULTI-SPEAKER COMPATIBILITY] The 2-pack includes enough sponges for stereo systems or dual-port subwoofers. Durable open-cell construction withstands repeated insertions. Works with wood, plastic, or metal port tubes in home, car, and professional audio applications.
