The Primacoustic FullTrap is broadband absorber and bass trap designed to work in conjunction with Broadway panels or other acoustic devices. The FullTrap provides balanced treatment by absorbing all frequencies including low bass frequencies.

This is achieved by combining three acoustical principles into a single device.

1. To handle mid-range and upper frequencies, a 3" thick front absorptive panel made from 6 lbs. per cubic foot high-density encapsulated fiberglass is employed.

2. Behind the acoustic panel is a stretched diaphragmatic dense-mass membrane that acts as a low frequency resonator to absorb bass down to 75Hz.

3. Behind the membrane, an air cavity is created by the wood enclosure which serves to further attenuate bass in the troublesome 100Hz region.

The FullTrap enclosure is made from MDF wood composite with a black, easy to clean melamine finish and ships flat to save freight. Final assembly is performed on site using a simple household screwdriver and building a MaxTrap takes about 15 minutes from start to finish!

Test data provided by Bodycote Materials Testing Inc. This method, designated as ASTM E 84-05, "Standard Method of Test for Surface Burning Characteristics of Building Materials", is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire-hazard or fire-risk assessment of the materials, products, or assemblies under actual fire condition. Fire and burn test data applies to the Broadway acoustic panel only and does not include the MDF wood encasement or the diaphragmatic membrane for fire-hazard or fire-risk assessment. Please consult your local building authority and/or insurance underwriter to ensure the product meets local building codes.

Due to the size of the wavelengths and limitations of the testing facilities, low frequency absorption data is based on a combination of Broadway panel test results from Riverbank Acoustical Laboratories and 1/4 wave length calculations.
