Techlite® Designer Crown Acoustic Panels in Obsidian™ introduce sculpted contour and controlled sound absorption into contemporary interior environments. The crown geometry creates subtle curvature and shadow lines that elevate flat ceiling and wall planes into architectural features. For architects, this profile supports intentional spatial articulation; for interior designers, it adds texture and visual depth; for sound engineers, it increases effective surface interaction to enhance reverberation control and speech intelligibility.

Fabricated utilizing Basotect® Ecobalanced Melamine Foam, the panel delivers exceptional acoustic absorption within a lightweight, open-cell structure designed specifically for interior applications. The material’s performance characteristics support balanced frequency control while maintaining dimensional integrity and clean installation lines. Each panel is Class A fire-rated per ASTM E 84, providing critical life-safety compliance for commercial, institutional, and specialty interior projects.

The Designer Crown panel is well-suited for corporate offices, lecture halls, hospitality venues, houses of worship, and performance spaces where both acoustical clarity and design sophistication are priorities. In addition to acoustic performance, the material composition may contribute toward LEED credits in areas such as low-emitting materials and responsible material transparency—supporting sustainable design initiatives without compromising architectural intent.

Obsidian™ Coloration & Visual Character

Obsidian™ is a deep, dark charcoal acoustic foam with subtle blue undertones. Depending on lighting conditions, it can range from a rich charcoal gray to a dark navy hue—and when installed in high ceilings or low-light environments, it presents as visually black.

The result is an acoustic material that integrates seamlessly into contemporary architecture while delivering the performance Techlite® is known for. For applications requiring an ultimate, rich black appearance, Obsidian™ panels may be coated utilizing Techlite®’s proprietary paint system.

Absorption results tested in accordance to ASTM C 423-09a

Sound Absorption

Sound Absorption Testing to ASTM Standard C423-09a indicates a better than 90% absorption coefficient at a frequency of 2000 Hz when using 2” thick TechLite® foam. Combined with a Class A fire rating, excellent thermal insulating value, its light weight and low toxicity, TechLite® is an excellent choice for your application.
