Unika Vaev | Ecoustic® Quad, a high-performance modular acoustic tile, employs gentle interplay of light and shadow from understated rather than dominant shapes, creating a style that beautifully complements a wide range of interior design schemes. Ecoustic® Quad is finished with a surface shadow line which visually divides each tile into four equal quadrants. Infill panels which further enhance acoustic performance are available for each of the three Ecoustic® Quad tile depths.
