Modex ™ LF
PRODUCT OVERVIEW The Modex™ LF Panel is designed to target the mid and upper bass frequencies utilizing an internally damped resonant panel, efficiently attenuating frequencies in the octave range between 80 and 160Hz, considered the mid-range of the bass frequency range. This range is often responsible for the bass buildup we are most sensitive to in mid-size auditoriums and band rooms, reducing musical clarity and intelligibility. SIZING • Standard Panel: 3'-6" W x 7' L x 5-1/4" T (Custom panel widths and lengths are available) • Published performance data is based on standard panel size. Dramatically smaller panel will have different results. . • Each panel weighs approx. 2.00 lbs/ft 2 . FIRE RATING All Class A Components FINISH The Modex™ LF Panel can be wrapped with RPG- reviewed industry standard and custom fabrics. Fabrics with acoustical performance data preferred. INSTALLATION The Modex™ LF Panel can be quickly and easily hung on any wall or ceiling surface using the RPG- provided wall cleats.
