The Primacoustic FullTrap is a combination full range absorber and diaphragmatic resonator designed to control all frequencies right down to the deepest bass.

This is achieved by combining a full-size high density glass wool panel (F) with a closed air space behind (B) created by the wood frame (A) to absorb sound down to 100Hz. Lower frequencies pass through the front face and then cause the internal diaphragm (D) to resonate. The greater energy contained in low frequencies causes the limp-mass diaphragm to naturally migrate to the frequencies where room resonance is most prominent, thereby reducing modal distortion.

Made from easy to clean black melamine coated MDF wood composite (A), the FullTrap ships flat in kit form to save freight costs and assembles in about fifteen minutes using standard household tools. Once together, the device is wall mounted using the supplied French cleats.

The FullTrap may be ordered in a choice of black, grey or beige to suit most color schemes.
