Foam Panel Category — 4-Pack Fiberglass Soundproofing Panels — 23.6×11.8 inches each, 2 inches Thick, Deep Black, Suitable for Recording Studios, Offices, and Home Theaters

This product represents the professional-grade tier within the acoustic panel category. Unlike standard polyurethane foam panels, these units are constructed from high-density fiberglass wool encased in a black acoustic fabric covering. Each panel measures 23.6 × 11.8 inches (approx. 60 × 30 cm) with a thickness of 2 inches; they are sold in packs of four. With a material density of approximately 48 kg/m³, these panels offer sound absorption performance far superior to that of standard foam: the NRC (Noise Reduction Coefficient) exceeds 0.95, covering a broad frequency range from a low 125 Hz up to a high 4 kHz. The fiberglass core is encased in a black, acoustically transparent non-woven fabric to prevent fiber shedding, and the edges are sealed for a clean finish. This product is typically utilized in professional recording studio control rooms, cinema mixing rooms, and acoustic laboratories where exceptional sound absorption is required. The 2-inch thickness provides robust low-frequency absorption capabilities, effectively reducing standing waves within the 80 Hz–250 Hz range. Installation Method: Panels must be suspended using wooden frames or specialized mounting hooks (direct adhesive application is not recommended). Each 4-panel pack covers a total surface area of ​​approximately 7.8 square feet. Due to the material’s rigidity and weight (each panel weighs approximately 1.5 kg), installation by professional acoustic technicians is recommended. The deep black finish presents a professional and understated aesthetic that is non-reflective. Note: Please wear a dust mask and gloves when cutting the material. Included with the product is an acoustic design consultation card, offering access to free online guidance.
