Modex™ Module

RPG Modex™ module

Small rooms often exhibit poor low frequency response with significant emphasis at modal resonances. They also have limited space to make acoustical improvements.  Porous surface absorption is ineffective at these modal frequencies, because the air motion near walls and in corners is essentially zero for these long wavelengths.  RPG® research solved this dilemma by developing a unique membrane system that converts the high sound pressure fluctuations typically found in corners into selective absorption in the modal frequency range.

Problem

Small rooms like Project Studios 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.

Features

• Pressure zone membrane absorber - Shallow 7'' depth offers optimal absorption - Stackable
• Wall or free standing mounting - Lightweight - Portable - Modular

Benefits
 

• The Modex™ Module's proprietary internally - damped membrane converts any available wall or ceiling into a highly absorptive low frequency absorber
• All Modex™ modules are modular and can be added as needed. The modules simply stack on top of one another and offer unlimited opportunity for experimentation and modification
• Modex™ can be applied to walls, ceilings, corners or mounted free standing
• Bass management in the sub-woofer region is now simply a matter of attaching Modex™ to walls, ceilings or corners
• Modex™ modules can be upholstered and visibly installed or concealed behind ceiling clouds, soffits or stretch fabric systems
• Modex™ Plus Modules (12" in depth) offer absorptive chevrons between the room and the membrane to extend absorption to cover the 40Hz frequency

Applications

All critical listening rooms including recording studios, Vocal booths, home theaters, Quality control rooms, CD mastering, Film mix and dubbing stages and music practice rooms
