The Primacoustic FullTrap is a highly effective bass trap that combines a diaphragmatic resonator, a full-size acoustic panel, and a sealed enclosure to provide 3-way absorption throughout the full frequency spectrum.
This unique design begins with a front-mounted 24" x 48" - 3" thick Broadway panel made from 6lb per cubic foot high-density glass wool fiber. This effectively absorbs frequencies down to 125Hz and extends below 100Hz. Behind the panel, a closed air space takes full advantage of quarter-wavelength principles to further reinforce low frequency absorption in this critical bass region.
But where the FullTrap truly shines is in its capacity to absorb deep low bass. The FullTrap's remarkable low frequency extension is achieved by way of a suspended diaphragm that stretches nearly the full height of the device and essentially acts like a huge microphone, capturing bass by vibrating where the low frequencies are most prominent. As room modes combine, they either reinforce certain frequencies or cancel them out. The FullTrap's limp-mass structure naturally migrates to the most powerful frequencies where it quietly resonates to remove excess bass and subsequent modal frequencies.
Available in black, beige or grey, the FullTrap ships flat and assembles in minutes using standard household tools. The FullTrap is the perfect solution for bass trapping in rooms where corner mounting is not an option due to windows, doors, or other obstacles. The FullTrap can also be used to reinforce other traps when a room demands additional bass control. When combined with Primacoustic Broadway panels and diffusers, one can turn virtually any room into a well-balanced acoustic space.
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.
