The Intertechnik TYROTEX-N20 Fireflex Acoustic Damping material is a high-performance solution for reducing unwanted cabinet resonances and midrange coloration in loudspeaker builds. Designed specifically for speaker attenuation, this flexible, open-cell foam effectively absorbs internal reflections, ensuring a cleaner, more accurate sound reproduction from your enclosure.

Ideal for both DIY enthusiasts and professional audio engineers, this damping material is perfect for lining the internal walls of speaker cabinets, subwoofer boxes, or any acoustic enclosure where controlling standing waves and panel vibrations is critical. Its lightweight yet dense composition makes it suitable for a wide range of applications, from hi-fi speakers to PA systems, where sonic clarity and precision are paramount.

With a density of 20 kg/m³ and dimensions of 1000 x 500 x 42 mm, the TYROTEX-N20 offers excellent absorption across the mid and high frequencies. The open-cell structure maximises surface area for trapping sound energy, while the Fireflex designation indicates enhanced fire resistance for added safety. Easy to cut and shape, it conforms neatly to curved or irregular cabinet interiors, providing a seamless fit that optimises acoustic performance.
