​​​​

At Arthur Acoustic, we specialise in the installation of the BASWA Phon Classic Fine system, the industry's premier choice for achieving high-performance sound control without sacrificing architectural purity. This two-coat system provides a smooth, monolithic surface that seamlessly integrates into any design, from ultra-modern minimalist galleries to sensitive heritage restorations.

High-Performance Sound Absorption Meets Sophisticated Aesthetics


The Classic Fine finish is the ideal "middle ground" in the BASWA range. It offers a significantly smoother texture than the standard Base system while delivering superior acoustic performance compared to ultra-thin alternatives. With a fine 0.5 mm marble grain, it provides a sophisticated, light-reflective surface that handles grazing light and complex geometry—including domes and vaults—with exceptional precision.
