RPG® Is The Acoustical Reference Of The Music Industry

RPG® Diffusor Systems, Inc. is unique in the music industry. This is due to the depth of its commitment, the wide range of its expertise and products, the quality of its products, continuous innovation, and the respect from other manufacturers and industry professionals. When you listen to your next CD, movie, video, radio broadcast, or live concert, are hearing RPG® technology at work, because RPG® is now used in every facet of the music and entertainment industry.

RPG® has worked behind the scenes and played a supporting role for over 15 years and is the industry's best kept secret to the end users. To the acoustical consultants, designer, specifiers, and music industry insiders however, RPG® has earned the reputation as the acoustical reference of the music and acoustical industries. Because of RPG®'s wide penetration into these industries, it is now regarded as the acoustical cornerstone.

RPG® was founded by Dr. Peter D'Antonio (AKA Dr. Diffusor)

RPG® was founded in 1983 by Dr. Peter D'Antonio, a physicist and acoustician with an international reputation. Dr. D'Antonio has numerous publications in reviewed scientific journals, text books, and magazines, many registered trademarks and patents and has been an altruistic educator in seminars offered at the Audio Engineering Society (AES), Synergetic Audio Concepts, CEDIA, NSCA, Acoustical Society of America, National Council of Acoustical Consultants, etc. He is a Fellow of the AES, a Fellow of the Acoustical Society of America, a professional affiliate of the American Institute of Architects, Chairman of the AES Characterization of Acoustical Materials committee, member of the ISO Random Incidence Scattering Coefficient working group and adjunct professor of acoustics at the Cleveland Institute of Music and the Peabody Conservatory of Music. His research has also been extensively covered in several text books including The Master Handbook of Acoustics, by F. Alton Everest and Sound System Engineering by Don and Carolyn Davis.

Dr. D'Antonio has also been associated with the music industry since 1973 as a musician, recording engineer and audiophile. In 1973 he designed Underground Sound, the prototypical studio which set the stage for modern control room design. This studio defined the philosophy of combining a reflection-free zone, RFZ™ around the mix position and a diffuse zone using RPG® diffusors in the rear, to provide passive surround sound.

RPG® Products Minimize Acoustic Distortion

Dr. D'Antonio indicates that "in the early 70s there really was no acoustical products industry aside from fabric wrapped fiberglass and sculptured foam absorbing products. Diffusors were simply not a part of the acoustical palette. Recording studio design was a trial and error experience with some successes and some failures."

Dr. D'Antonio claims that "In those days there was a clear difference between the recording hardware and the acoustical design in professional and 'semi-pro' studios." In the early 80s Dr. D'Antonio set out to identify the problems and goals of modern studio design and developed the concept of a reflection free zone around the mix position from early research by Don Davis, Chips Davis, Russ Berger and Neil Grant in Live-End-Dead-End studios.

To complete the design, Dr. D'Antonio then developed the reflection phase grating diffusor or RPG®, which attenuates the reflections from the control rooms rear wall and provides enveloping surround sound. Today, RPG®s are standard fare in recording studios and RPG® research has set the standard for modern recording studio design. RPG®'s products and research design concepts have been used in over a thousand facilities worldwide, with tens of thousands of diffusor systems installed.

Today, recording studios have changed from the early 70s. Dr. D'Antonio indicates that "The gap between professional and what is now called 'project studios' has narrowed significantly with digital recording and processing. However, the acoustical gap is even wider due the modern acoustical digital measurement equipment, talented studio designers, and passive acoustical products and designs such as the RPG® Diffusor Systems.

To bridge this last acoustical gap, RPG® developed a series of cost effective acoustical packages containing reflection control products, such as the Abflector™, new Polyflex™ and fire-safe Melaflex™ ProFoam™ and ProCorner™ acoustical foam, the Flatffusor™ digital diffsorber, dedicated low-frequency Modex Corner modal absorbers, and a new 2-dimensional number theoretic sound diffusor called the Skyline®, & Skyline®LP which is the most effective diffusor ever developed. The VariScreen™ free standing variable acoustics panel and the Room Optimizer™ software rounded out the acoustic tools needed for project studios." RPG® also provides its expertise in placing these AcousticTools® appropriately in the room for optimum effect.

RPG® Is Your Acoustical Microscope

Now project studio owners can have both cost effective digital hardware, as well as digital AcousticTools®, to create a modern control room with sonic accuracy, reproducibility, and transferability.

Sonic accuracy means we can hear the music with correct frequency balance, accurate images, and appropriate envelopment. This makes it possible to properly and easily adjust volume balance, panning, equalization, reverberation, and other signal processing.

Reproducibility means we can create these modern control rooms repeatedly so that each room in a multi-room facility can now offer the same neutral monitoring environment.

Transferability is also now in reach. You can finally be assured that the mix you create in your project studio will not only be accurate, but it will sound the same in another properly treated project studio. Your creativity is now transferable.

RPG® Research Leads The Music Industry

One additional aspect of RPG®'s industry dominance is its research. RPG® Acoustics Research, headed by Dr. Peter D'Antonio, has published numerous technical papers in reviewed acoustical journals. Their products are painstakingly tested for absorptive and diffusive performance. In fact, Dr. D'Antonio has developed the pending diffusion coefficient standard to evaluate potential diffusing surfaces. This reliance on research and documentation has won RPG® the respect of the international acoustical community.

The effectiveness of RPG® Acoustics Research is evidenced by the fact that Mix Magazine Technical Award Winners for studio design and acoustics — including Bob Todrank, Chips Davis, Russ Berger, John Storyk, and Studio Bau:ton — are avid RPG® specifiers. In fact, RPG® has itself been nominated for TEC awards.

RPG® is also specified by professional acousticians and select members of the National Council of Acoustical Consultants. This body of acoustical professionals is very discerning in the products they specify, because their integrity and reputation depend on it. RPG® has won this trust.

In addition to developing the template for modern control room design, RPG® has sold tens of thousands of diffusor systems to over a thousand facilities worldwide. This means that when it comes to making a choice about purchasing acoustical conditioning for your project studio, RPG® offers you a proven track record of successful performance.

In its 15 year history, RPG® has established a track record for delivering the highest acoustical performance and is considered the acoustical reference of the music industry. Remember their slogan: "Listen to the Music, Not the Room!"
