Walls

The DiffusorBlox^® Family of acoustical concrete masonry units (CMU), slotted (S) and non-slotted (NS), offers unprecedented economy by making it possible to incorporate complete acoustic performance into the structural walls of music, speech, athletic and multipurpose facilities. DiffusorBlox^® simultaneously offers a distinctive appearance, extended low-frequency absorption, sound isolation and sound diffusive reflection control, They can also be incorporated into standard CMU walls.

The Modex^TM Corner is a unique membrane system that converts the high sound fluctuations typically found in corners into selective absorption in the modal frequency range, Studio control, home theaters, and dedicated listening rooms often exhibit poor low frequency response with significant emphasis at modal resonances. Porous surface absorption is ineffective at these modal frequencies because the air motion near walls and in corners is near zero for these long wavelengths. The Modex^TM Corner is designed to be installed in corners and is available in tuning frequencies of 40, 63 and 80Hz. They are designed to cover approximately 1/3 octave above and below the tuning frequency.

Many rooms, such as studio control rooms and home theaters, often suffer from low-frequency modal problems that cannot be mitigated using porous materials like fiberglass. RPG's Modex^TM Edge resolves these problems by offering significant broadband width absorption down to the axial mode frequencies. The carefully engineered tuned resonator system acts as a high-pass filter for your room while eliminating the low-frequency modal emphasis that prevents accurate monitoring.
