Small rooms like Project Studios often suffer from low frequency modal problems, where certain bass frequencies build up, providing a distorted picture of the source material. 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 needs to be optimized.
The Modex Corner Bass Trap from RPG solves this problem by utilizing a damped membrane absorber. Sound waves strike the membrane which sympathetically vibrates, converting the sound pressure to air motion. The air loses velocity as it moves through the internal absorber and air cavity, allowing the bass trap to absorb more bass in less space.
The Modex Corner can be mounted in any 90° corner between two walls or a wall and a ceiling and can be attached directly to the surfaces using the supplied hook and loop or metal screw fasteners. If there is no 90° corner available, or if the corner is not suitable, the Modex Corner can be stacked in a free standing configuration.
The trap comes in three tuned versions, 40, 63 and 80Hz. They are each recommended for rooms that have a 14, 9 or 7 foot distance between any two parallel surfaces, respectively.
Applications include all critical listening rooms, such as recording studios, broadcast studios, vocal booths, home theaters, quality control rooms, CD mastering, film mix and dubbing stages and music practice rooms.
