Q11D Quadratic Residue Diffusers
Performance You Can Trust
Every GIK product is tested at the world-renowned University of Salford, following BS EN ISO 354:2003 standards. This scientific approach not only ensures complete transparency in how our products perform, but also drives our R&D process. So every panel, bass trap, or diffuser we release is engineered to deliver results you can trust.
Product Description
Specifications
Materials
Camira Cara Fabrics
GIK is excited to use the Camira Cara fabric line standard in all our products. The Camira fabric will look familiar to fans of Guilford of Maine fabrics, similar to their FR701 line but with different color options. With a richer aesthetic and tactile feel and wider range of available colors compared to our previous standard offerings, Camira Cara allows every product to look as good as it performs.
Sustainability
GIK Acoustics has long prioritized sustainability as a guiding principle. We carefully select materials that balance acoustic performance with environmental responsibility, sourcing from suppliers who share our commitment to reducing waste and carbon impact. Our products use durable, recyclable components that minimize landfill waste while maintaining the highest acoustic standards.
Health & Safety
Health and safety are built into every GIK product. All materials—including fabrics, cores, and wood elements—are formaldehyde-free, low-VOC, and independently tested for indoor air quality. This ensures our treatments are safe for studios, homes, schools, and offices alike. We believe superior acoustics should never come at the expense of well-being, which is why our products are made with clean, non-toxic materials that protect both the people who use them and the spaces where they’re installed.
Care Instructions
