The Primacoustic FullTrap is a combination broadband absorber and bass trap that is mounted on a wall surface to control excessive bass in a room. This is achieved by combining three acoustical principles into a single device.
To handle mid-range and upper frequencies, a 3" thick front absorptive panel made from 6 lbs. per cubic foot high-density encapsulated glass wool is employed. Behind the acoustic panel is a diaphragmatic dense-mass membrane that acts as a low frequency resonator to absorb bass below 75Hz. Behind the membrane is an air cavity that is created by the wood composite enclosure which serves to further attenuate bass in the troublesome 100Hz region.
The FullTrap enclosure is made from MDF wood composite with a black, easy to clean melamine finish and ships flat to reduce freight costs. Final assembly is performed on site using a simple household screwdriver. Building a FullTrap takes about 15 minutes from start to finish. The FullTrap is available in a choice of three panel colors: black, beige and grey.
