Vibrofiltr Autoshim Black Layer 7mm Polyurethane Foam | 50x50cm

The Autoshim Black Layer 7mm Polyurethane Foam from Vibrofiltr is a purpose-engineered acoustic treatment designed to elevate the performance of your loudspeaker enclosures. This 50x50cm sheet offers a simple yet highly effective solution for reducing unwanted cabinet resonance, thereby improving midrange clarity and overall sound fidelity. Ideal for DIY speaker builders, audio enthusiasts, and professional technicians, this foam panel can be effortlessly cut to size and fitted inside enclosures to dampen internal reflections and standing waves. Whether you are upgrading a vintage pair of speakers or constructing a new high-fidelity system, this material provides a cost-effective means of achieving a cleaner, more accurate audio reproduction. The 7mm thickness strikes an optimal balance between absorption and space efficiency, making it suitable for a wide range of cabinet volumes. Technically, the polyurethane foam features an open-cell structure that effectively dissipates acoustic energy, while the black layer adds a discreet, professional finish. With a density carefully calibrated for speaker attenuation, it targets problematic frequencies without over-dampening the enclosure’s natural character. Easy to work with and durable, the Autoshim Black Layer is a reliable choice for any serious audio project seeking to minimise coloration and enhance transient response.
