Use Sonic Barrier 1 coated acoustic damping foam to control unwanted sound reflections and absorb extraneous acoustic energy. Key Features: Reduces unwanted sound reflections Helps absorb unwanted sound from within speaker cabinets Exclusive embossed surface finish helps trap acoustic energy Pressure sensitive adhesive provides easy permanent installation Sold in 18 x 24 sheets Sonic Barrier 1 Acoustic Sound Damping Foam with PSA 18 x 24 The Sonic Barrier 1 acoustic damping foam is a precisely engineered material that offers optimum absorption for its thickness. The material features our exclusive embossed surface finish that helps to trap acoustic energy and improve high frequency performance. This finish is applied to an acoustic-grade open-cell polyether foam which absorbs and converts the acoustic energy into low-level heat. A very aggressive pressure sensitive adhesive provides easy and permanent installation onto any surface. The Sonic Barrier 1 foam is excellent for general loudspeaker cabinet use. The non-composite nature of this material means that it acts as a sound absorbent across a wide range of frequencies. For situations where the cabinet walls are already acoustically dead composite barriers may not be necessary-in this case the pure foam material can offer a lower-cost alternative with minimal difference in performance. The foam will help absorb unwanted sound from within the cabinet without disrupting airflow between the driver and port. This can reduce unwanted sound reflections and prevent them from exiting through the cone or port. The foam can cause an increase in apparent volume which can help to offset the space taken up by the driver or the port.
