Intertechnik BONDUM800 Acoustic damping | 300 x 500 x 20 mm

The BONDUM800 sound-absorbing material from Intertechnik is a high-density acoustic damping sheet designed to significantly reduce unwanted cabinet resonance and midrange coloration in loudspeaker enclosures. By effectively absorbing standing waves and suppressing internal reflections, this 8 mm thick material ensures a cleaner, more accurate sound reproduction from your speaker build. Ideal for both DIY enthusiasts and professional audio engineers, BONDUM800 is particularly suited for use in closed and bass-reflex cabinets where internal acoustic treatment is critical. It excels in taming midrange frequencies that often cause muddiness or boxy coloration, making it an essential component for high-fidelity speaker projects. Technically, the material features a dense, fibrous composition that converts acoustic energy into minute amounts of heat, thereby reducing the amplitude of internal resonances. Its 8 mm thickness provides optimal absorption across a broad frequency range without adding excessive weight or bulk to the enclosure. The sheet is easy to cut and shape, allowing for precise fitting inside cabinets of various geometries. For best results, apply BONDUM800 to the internal walls opposite the driver and around the rear panel. This product offers a reliable, cost-effective solution for achieving cleaner, more transparent sound in your custom speaker designs.
