40th Year Celebration

RPG Acoustical Systems, LLC, a leading provider of premium-grade innovative acoustic solutions for environments of all kinds, is proud to celebrate 40 years of diffuser technology development. In 1983, Dr. Peter D’Antonio founded RPG Diffusor, where he pioneered the sound diffusion industry and contributed to developing the diffusion and scattering coefficient international standards. We take great pride in the work of Dr. D’Antonio, recognized as a foremost innovator in the acoustics industry and holder of numerous patents and trademarks. Dr. D’Antonio is the author of the acoustics industry’s reference text “Acoustic Absorbers and Diffusers: Theory, Design and Application, 3rd Edition, CRC Press (2017)” and has been inducted into the music industry’s TECnology Hall of Fame.


In 2017, a new entity known as RPG Acoustical Systems, LLC was established to go forward with the production and sale of a full line of absorption, reflection and diffusion products at our facility in Passaic, New Jersey. RPG Acoustical Systems continues its legacy by adding new milestones and expanding its product range to meet the ever-changing requirements of the architectural acoustics and pro audio industries.


Today, we offer a diverse range of high-quality products, including diffusers, absorbers, reflectors, and other specialized acoustic solutions, as well as testing and modeling services in our new Acoustical Research Center (ARC).


As we celebrate 40 years of acoustics technology, we would like to express our sincere appreciation to our valued customers, partners, and employees who have contributed to our success. We also honor the countless innovations and contributions to the field made by Dr. D’Antonio. We at RPG are committed to providing the highest level of service and quality products, and we look forward to many more years of innovation and growth.


Thank you for your ongoing support; we look forward to collaborating with you in the years to come.


With much appreciation and gratitude,


Your friends at RPG Acoustical Systems
