Specifically engineered to cut 100Hz boominess.

Primacoustic Australis acoustic foam bass traps are effective at controlling low frequencies which are below the bandwidth of 3" foam.

Studio acoustics is more than covering every surface with foam. Primacoustic diffusers and bass traps are based on long-standing studio acoustic principles, and engineered to integrate into any environment.

The Primacoustic Australis is a high-efficiency bass trap that controls low frequency energy. Introducing Australis in a studio will result in a tighter, more controlled bass.

Made entirely from a solid block of 100% high-density, open-cell acoustical polyurethane foam, the Primacoustic Australis measures 12" x 36" to provide maximum absorption in the least space. The unique wedge design allows easy placement in corners or on walls, offering tremendous flexibility to suit the most demanding architectural tastes. For even greater bass absorption, Australis can be stacked, grouped to form a wall cluster, or placed edge-to-edge at the wall and ceiling seam.

Australis works by trapping the random omnidirectional bass energy that tends to cluster in corners and overwhelm the room. Quarter-wavelength calculations prove that Australis is particularly effective for rooms with 8' ceilings that require 36" of absorptive materials to control the troublesome 100Hz region. This has the positive effect of reducing smear, giving bass more definition and punch while allowing recordings to translate better to other rooms. One pair, 12' W x 36 " H x 12" D each.

    Comments about Primacoustic Australis Bass Traps Pair:

    Over priced and under perform - Go w/ fiberglass core traps containing Owens Corning 703-705 or equivalent for bass traps w/ absorption performance coefficients that are nearly double the effectiveness of foam. You can virtually eliminate standing wave and low frequency reflections in corners of your room down to 80hz for about half the price of these foam wedges.
