The Primacoustic FullTrap does exactly what its name implies — provide 3-way sound absorption throughout the full frequency spectrum. This high-performance wall mount panel absorbs deep, low bass, allowing you to be confident that your mixes are as accurate as possible. A 3-inch thick Broadway panel effectively absorbs frequencies down to 125Hz. The FullTrap’s low frequency extension utilizes a suspended diaphragm that stretches nearly the full height of the panel, capturing bass by vibrating where the low frequencies are most prominent.

FullTrap Constrution

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.
