Modex™ Corner

RPG Modex™ Corner

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 at wall surfaces and in corners into selective absorption in the modal frequency range. As the use of sub-woofers becomes more and more popular
there is a growing need for modal frequency management.

Problem

Listening and performance rooms often suffer from low frequency modal problems. Because porous absorption is ineffective
at these frequencies, a high efficiency mechanism is needed to provide modal control.

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.

Sound (1) strikes the membrane (2) which sympathetically vibrates, converting the sound pressure to air (3) motion.
The air loses velocity (4) as it moves through the internal absorber and air cavity. Now you absorb more bass in less space!

Features

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

Benefits
 

• The Modex™ Corner (formerly Corner Bass Trap) provides useful low frequency absorption in wall and wall ceiling corners that are often unused and available for acoustical treatment.  This means you don't have to sacrifice space for equipment
• 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 40- 10,000

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
