Modex Module

MDXM MAIN

Overview

The Modex Modules are low frequency membrane sound absorbers designed to fine tune the modal distribution in a small room such as a studio control or music listening room. The tuning frequencies available for Modex Module are 40, 50, 63, 80, 100 and 125Hz. The units are designed to cover about 1/3 octave above and below the tuning frequency.

Finish

Select from industry standard and custom fabrics, fabrics with proof of performance acoustical data preferred. Natural wood framing is an option for a more finished unit.

Installation

Modex Module can be easily and quickly hung on any wall or ceiling surface using the provided Z-clips. Panels can also be configured to install in a standard, reinforced T-bar grid. See details below under the Drawings tab.

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 long wavelengths, resulting in very low absorption efficiency. RPG solved this dilemma by developing 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 wall and ceiling application also makes it ideal for use behind stretch fabric and integrated into soffited areas.

 

 

 

 

Problem

Small rooms like Home Theaters and Dedicated Listening Rooms often suffer from low frequency modal problems. Absorption at these frequencies requires a high absorption efficiency and significant surface area. Since small rooms do not offer the needed space, the absorption efficiency must be optimized.

Solution

RPG solved this problem by optimizing the absorption efficiency, using a unique internally damped membrane absorber that provides ideal absorption in the modal frequency range. Now you can absorb more bass in less space!
