Reflection Phase Grating Diffuser Systems
I invite you to learn the RPG Story from its founding as a result of the recording studio design at Underground Sound in the Prequel, through the Founding Years with detailed events and publications, through the Full Story spanning the years, to the sale and Sequel at RPG Acoustical Systems, LLC. All publication references in peer review journals, magazine articles and books can be referenced in my Google Scholar profile.
For over three decades, I have been dedicated to the development of innovative RPG diffusive and absorptive systems. If you need to improve the acoustics of your space, RPG acoustical systems are the perfect solution. For a more uniform sound that balances absorption, reflection, and diffusion, look no further.
The Background of RPG Diffusor Systems
While we have developed some of the highest performance acoustical solutions, I continue to research, test, and develop new systems that provide even better results. RPG diffuser and absorber systems are currently provide the state-of-the-art environment for recording, home theater and performance spaces, but there is always room to improve.
My goal is a continual commitment to fundamental acoustics research to expand and improve the acoustical palette of products, designs, and services. Learn more about the development of new and improved RPG diffusor systems and how I continue to look for new ways to improve the architectural acoustics industry.
Explore the major milestones of RPG acoustical systems thus far, as well as the defacto design of critical listening rooms and the invention and standardization of the Goniometer for measuring diffusion and scattering coefficients.

The First RPG Diffusor Paper
This research was presented at the 74th AES Convention in New York 1983
Announcing the RFZ/RPG Control Room Design
A new de facto control room international standard
This design evolved from the Live End Dead End design of Don and Carolyn Davis and created a new recording control room design, which has withstood the test of time
RFZ Geometry
The Invention of the Goniometer
In 1983, when RPG introduced the first commercial reflection phase grating, there was a need to develop an experimental testing method to compare with theoretical predictions. This led to the development of the acoustic goniometer
