Self-Adhesive Felt Flannel Subwoofer Speaker Liner

Upgrade Your Speaker Finish and Sound Control

This self-adhesive felt flannel sound-absorbing cotton sticker is designed for users who want a clean, professional finish on their speakers while improving basic acoustic control. Supplied in a 0.5 x 1 meter sheet, it can be trimmed and applied to a wide range of enclosures, including KTV stage speakers, home theater subwoofers, car subwoofer boxes, instrument cabinets, and indoor acoustic panels. The dense felt flannel surface provides both a neat visual appearance and additional sound-dampening performance for your setup.

The backing features a strong adhesive layer, allowing you to apply the material directly to wood, MDF, and other common cabinet surfaces without extra glue or tools. Simply cut to size, peel, and press into place. The flexible construction conforms to flat, curved, and slightly uneven surfaces, helping to cover existing marks, joints, or imperfections on older speaker boxes. Once installed, the felt flannel layer helps to reduce internal reflections and surface resonance, supporting clearer, more controlled audio output in small to medium rooms such as KTV rooms, project studios, and living rooms.

Thanks to its wear-resistant and impact-resistant structure, this material is suitable for speakers and cabinets that are frequently moved or transported. It can also be used as a protective and sound-absorbing lining for car trunks, equipment cases, and other DIY acoustic projects where a durable textile finish is required.

Why It's a Smart Choice

• Improves basic sound absorption to help reduce echo, resonance, and microphone howling in small KTV rooms and similar spaces.
• Self-adhesive backing allows quick DIY installation without additional fasteners, glue, or special tools.
• Durable felt flannel finish refreshes the appearance of old cabinets while resisting wear, scuffs, and everyday impact.
