The Expo panel system is the ultimate synergy of acoustical technology and architectural panel design. Utilizing an optimal binary pattern of perforations through a Class A fire rated, FSC certified wood panel, the Expo achieves an excellent balance of sound absorption across the NRC frequency bands while preserving the ambiance of the space with high frequency diffusion.
The Expo panel system comes in a wide variety of finishes, including wood veneer, laminates, melamine coatings and painted surfaces. See some of the options displayed under the Finishes tab below.
Mounting options include wall panel systems with a variety of cavity depths starting at 1-5/8″ total system depth, as well as suspended ceilings including options for T-Bar, partial access and a complete access torsion spring system. See details below under the Drawings tab.

Expo Panel System
Well balanced acoustical design contains an appropriate combination of absorption, reflection, and diffusion. In many applications, however, limited budget or available surface depth can preclude the use of sound diffusion products. If too much absorption is used, especially products that are efficient at absorbing sound in the high frequencies such as foam and fiber glass, it can lead to an acoustically “dead” environment without “air” or ambiance.
To solve this problem, RPG integrated its BAD technology into a decorative, natural wood panel solution that achieves balance between sound absorption and reflection. By perforating a 5/8″ thick, fire rated panel and backing with acoustical fleece and fiberglass, RPG has successfully created a surface that eliminates excessive high frequency absorption, prevents lobing effects inherent in common perforated surfaces and significantly improves mid and low frequency absorption.
RPG Expo Panels consist of a binary amplitude panel backed with an acoustical fleece and porous absorbing core, typically a rigid fiberglass board with appropriate density for optimum performance. Panel edges are veneered or painted and can be square, with a slight radius or mitered depending upon the requirements of the project. The panels can be mounted in a fixed or removable fashion utilizing z-bar for wall applications or with any of several suspended metal grids for ceiling accessibility.
Traditional absorptive wood panels offer reflection and reverberation control. However, these panels can also contribute undesirable acoustical effects based upon how they are perforated.
RPG developed a decorative and innovative variable impedance wood panel by applying an acoustically optimized perforation pattern which eliminates lobing effects. RPG offers complete, quality assured custom panel fabrication that provides a simple and reliable fixed or removable mounting.
