Planar Acoustic Bass Trap - Obsidian™

Techlite® Planar Acoustic Bass Trap in Obsidian™ is a low-profile acoustic solution designed for architects, interior designers, and sound engineers who need effective low-frequency control without overpowering the visual language of a space. Formed from Basotect® Ecobalanced Melamine Foam, it helps manage bass buildup in corner conditions while maintaining a crisp, contemporary presence suited to studios, media rooms, performance environments, and other acoustically sensitive interiors. Its planar geometry offers a more restrained expression than traditional corner treatments, making it easier to coordinate with modern ceilings, wall transitions, and integrated room concepts. For design teams, this means an acoustic element that supports the overall composition of the room. For sound engineers, it provides targeted treatment for low-frequency resonance and corner accumulation. For interior designers, it introduces a dark, architectural finish that complements restrained palettes and layered material schemes. Beyond acoustic control, Techlite® Planar Acoustic Bass Trap supports project goals tied to healthier and more efficient interior environments. Basotect® Ecobalanced Melamine Foam can contribute to LEED-related design considerations through material stewardship and indoor environmental priorities, while the product’s lightweight format can simplify installation planning. The material is also Class A fire-rated per ASTM E84, aligning performance expectations with interior commercial and specialty applications. 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.
