Intertechnik PYR70 Acoustic Damping | 100x50x7cm

The Intertechnik PYR70 sound-absorbing material is a high-density acoustic damping sheet engineered to significantly reduce unwanted cabinet resonances and midrange reflections in your speaker builds. This premium polyester fibre material, with a density of 70 kg/m³, provides exceptional performance for audiophiles and DIY enthusiasts seeking to refine their loudspeaker projects.

Ideal for use in bookshelf speakers, floor-standing towers, and subwoofer enclosures, the PYR70 effectively absorbs standing waves that can colour the sound and degrade clarity. It is particularly beneficial for damping internal reflections in the midrange, where unwanted resonances often mask subtle details. Whether you are constructing a new pair of speakers or upgrading an existing design, this material helps achieve a cleaner, more accurate acoustic response.

Technically, the 70 kg/m³ density offers an optimal balance between absorption efficiency and ease of handling. The polyester fibre construction is lightweight yet robust, allowing for straightforward cutting and fitting into various cabinet shapes. Its open-cell structure traps sound energy across a broad frequency range, reducing flutter echoes and smoothing the overall frequency response. The material is also resistant to moisture and does not degrade over time, ensuring long-lasting performance.

In summary, the Intertechnik PYR70 is an essential component for any serious speaker builder aiming to minimise cabinet colouration and enhance sonic purity. By integrating this damping sheet, you can achieve a more transparent and natural sound reproduction from your loudspeaker projects.
