RPG Diffusor Systems: Triffusor

When your design calls for variable acoustics or acoustical scene changes, specify the Triffusor®.

The Triffusor® has its origins in an ancient theatrical device called a periaktoi (Greek for “revolving”) by which a scene or change of scene was indicated. It was described by Vitruvius in his De.architectura (c. 14 BC) as a revolving triangular prism made of wood, bearing on each of its three sides a different pictured scene. While one scene was presented to the audience, the other two could be changed. Although it was once thought to be a feature of Greek classical drama, it is now believed that it did not originate until the Hellenistic age.

The periaktoi was revived, notably for the Italian theatre around 1500 and for the 17th century English stage.

RPG has reintroduced the concept of periaktoi to the 20th century with an acoustical “twist”. The Triffusor® is a rotatable equilateral triangle prism with absorptive, reflective, and diffusive sides.

Diffusion	Variable Acoustics The Triffusor® was developed to make completely variable acoustics a reality. Triffusor® modules can be arranged adjacent to one another in a linear array so that they form a surface of any desired acoustical character. These arrays combine the basic acoustical building blocks of absorption, diffusion, and reflection. With the Triffusor®, small rooms take on a flexibility not possible before. You can easily adapt to the requirements of a particular situation and not be locked into a fixed acoustical environment. Even large rooms can be made more versatile by using movable Triffusor® partitions or gobos to alter the localized acoustics. The Triffusor® can also be flush mounted to form a variable acoustics wall. The effect of almost any acoustical treatment on the binaural perception and enjoyment of music can easily be demonstrated by applying Triffusors® along the walls and corners of a room. One can experience the effect of early reflections on stereo imaging and frequency coloration, the difference between the sensation of high localization and high spaciousness in a listening situation, the correlations between spaciousness and lateral diffuse reflections, and the benefits of a diffused rear wall. Installation Triffusors® should be mounted on a platform with height adjustments to compensate for floor irregularity. Rotation can be accomplished by using a quarter inch dowel or “lazy susan” type bearing to connect the center of the Triffusor® base and the mounting plinth. Dowel holes and bearings should be positioned so that Triffusor® modules meet at their edges when in position. Mounting hardware is not supplied. Triffusors® can also be stacked atop one another when taller columns are needed.
