Modex

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.

The Modex^TM LF is designed to target the mid and upper bass frequencies utilizing an internally damped resonant panel, efficiently attenuating frequencies in the octave between 80 and 160Hz, considered the mid-range of the bass frequency range. This frequency range is often responsible for the bass buildup that we are most sensitive to in mid-size auditoriums and band rooms, reducing musical clarity and intelligibility.

The Modex^TM Module Panel is a low-frequency membrane sound absorber designed to fine-tune the modal distribution in a small room such as a studio control, music/dedicated listening room or home theater. The panels have a unique membrane system that converts the high sound pressure fluctuations typically found where room surfaces meet into selective absorption in the modal frequency range.  The tuning frequencies available for Modex^TM Module Panel are 40, 50, 63, 80, 100 and 125Hz. The units are designed to cover about 1/3 octave above and below the tuning frequency.
