Primacoustic Broadway Broadband 24" X 48" Beveled Corners
24" X 48 X 2" - 6 per Box
The Broadway Broadband Absorber presents an attractive, 'easy-to-install' solution for acoustic treatment where maximum control over primary reflections is required. Made from high density six pound per cubic foot glass wool, the larger 24" x 48" (60.96cm x 121.92cm) Broadband features an increased surface area for great absorption. This makes it particularly effective at improving itelligibility in larger installations where the reverberant filed and echo is excessive.
Broadband Absorbers are flush mounted on the wall using Primacoustic Surface Impalers and can be 'butted-up' for complete wall coverage for maximum absorption or sread in an array to retian a sense of 'air' or natural ambiance in the room. This makes the Broadband particularly well suited to attenuate the reverberant flied and improve the working environment in commercial installations such as noisy offices, call centers and boardrooms. The larger panel design also lends itself to other applications such as bass management. For instance, mounting Broadband Absorbers using Primacoustic Off-Set Impalers introduces an air space behind the panel which can increase bass absorption by as much as one octave. When mounted using Primacoustic Corner Impalers, bass absorption extends down to 75Hz making it an ideal bass trap for controlling the low end response in a studio or home theatre installation.
Broadway Broadband Absorbers come in a choice of 1-inch, 2-inch and 3-inch thick panels with your choice of a square or bevelled edge. Color options include black, grey or beige.
Should additional bass attenuation be required, mounting Broadband Absorbers using off-set impalers can increase the performance by as much as one octave in low frequency region. Bass absorption can be extended further using Corner Impalers and stacking the panels.

*Notice: In our opinion, the short form sound absorption coefficient does not provide reliable data regarding the performance of a particular panel versus the problem frequency. This data is provided for comparison sake only. Please view the full frequency chart below to ensure that the panel you are considering will actually attenuate the frequencies you are attempting to absorb.
