Harmonix G

Edmond HS HRMX G e1513182002347


The Harmonix-G represents the evolution in architectural acoustics toward quantifiable, organic shapes. The surface of the Harmonix-G is designed to provide a more uniform sound field through mid and high frequency diffusion while the hard, GRG construction of the unit limits the amount of sound energy removed by absorption.


The Harmonix-G is readily available in a standard white, smooth, matte finish. Units can be color matched to any paint color specification. See some of the options displayed under the Finishes tab below.


The Harmonix-G is designed to drop into a standard T-Bar grid. It can also be flush mounted to a wall or ceiling with appropriate blocking. See details below under the Drawings tab.

RPG Utilized its patented Shape Optimizer and aperiodic modulation technology to develop the Harmonix G, an interesting and modern contoured surface that has the appearance of a bas relief sculpture. The center of each panel is asymmetric, however, the sides are identical. Therefore this unique acoustically optimized asymmetrical shape offers the opportunity to create an unlimited range of surfaces, determined only be the orientation of adjacent panels. The Harmonix G is fabricated from non-combustible glass reinforced gypsum for safety and economy and designed to provide optimal coverage with minimal low frequency  diaphragmatic absorption. This provides uniform coverage, due to optimal diffusion, lack of periodicity effects, due to aperiodic modulation and good low frequency support.






An “acoustic ceiling” has come to mean absorptive mineral or fiberglass tiles. Exclusive use of only mid-high frequency absorption in the ceiling cannot optimize the acoustics of spaces where music is to be enjoyed or speech is to be understood. The industry needed a complementary sound diffusing tile for these applications.


The Waveform Harmonix G is the first cost-effective, non-combustible GRG molded, 2D sound diffusor that offers uniform mid-high sound diffusion and minimal low frequency diaphragmatic absorption to provide optimal coverage with good bass support.
