Home Theaters and dedicated listening rooms often exhibit poor low frequency response with significant emphasis at modal resonances. This is especially true when they are sonically well isolated, due to massive boundary construction. Porous surface absorption is ineffective at these modal frequencies, because the air motion near walls and in corners is essentially zero , resulting in very low absorption efficiency. RPG developed its Modex line to address these problems. We are extremely proud to introduce a new and unique addition to the Modex line, called the Modex Plate. The Modex Plate was developed by the Institute for Building Pyhsics at the Fraunhofer Institute, and consists of a damped metal plate system. The Modex Plate offers broadband low frequency absorption effective from 50 – 500 Hz in a thickness of only 4 inches. The Modex Plate has an attractive powder coated metal finish and can be surface mounted on walls or ceiling. Every now and then a new technology comes along that changes everything. You will be astounded at the transients and clarity of sound, once the Modex Plate removes all of the masking low frequency reverberance. Now you can absorb more bass in less space!
