Made in USA

Auralex SonoFlat Panels provide a new and unique alternative for super, cost-effective sound control.  With an NRC of .95 they outperform other 2" panels and dramatically improve the sound quality of your acoustic environment.  Made of renowned high-density, open-celled Studiofoam, they will not rot or crumble over time.

SonoFlat Panels are painted throughout the foam, ensuring a uniform color even when trimming or cutting the panels to suit your design.  Panels are flexible and easy to trim preferably with an electric carving knife for optimal, aesthetic appeal.   Panels are uniformly cut and finished off with a stylish beveled edge thereby providing a seamless installation and professional appearance. They can be installed by anyone using Foamtak Spray or TubeTak Pro Adhesives.  

Can be used in conjunction with SonoColumns for added bass control for a complete room solution. 

PLEASE NOTE:  These panels are not fire-rated.  In applications where fire-rating is a priority, please see our Sonex Panels.
