Modex ™ Corner
PRODUCT OVERVIEW The Modex™ 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™ 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 octaves above and below the tuning frequency. STANDARD SIZING • Standard Panel: 23-5/8" W x 23-5/8" L x 12" D Note: Each side extends 15-1/2" from the 90 o corner along the mounting wall • Maximum Panel: 23-5/8" W x 8' L x 12" D • Triangular shape • Tuning Frequencies: 40, 63, and 80 Hz • Each standard panel weighs approx. 5.00 lbs/ft 2 FIRE RATING • All Class A Components FINISH The Modex™ Corner can be wrapped with RPG reviewed industry standard and custom fabrics. Fabrics with acoustical performance data are preferred. INSTALLATION The Modex™ Corner can sit freestanding on the floor or can be mounted to any 90° corner using RPG supplied hardware.
Green = 40Hz Absorption Red = 63Hz Absorption Purple = 80Hz Absorption
