Foot Low Frequency Absorber. These panels are loaded with high performance 6lb Rockwool Insulation. Each bass trap is crafted right here in the USA, using high grade cabinet plywood, and wrapped in our lavish Acoustimac Suede Fabric. All Acoustimac Bass Traps are wrapped on front and sides in fabric, and have a wooden backing. These Bass Absorber are Available in 4 colors and Include Easy to install Mounting Hardware and screws for wall deployments. They have an average NRC Rating of .95 or higher with additional absorption on the low end of the band spectrum, which makes them your best choice for treating for 'boomy' or 'muddy' bass as well as standing waves in studios or home theaters. They also have the same mid and high frequency absorbers as our 2" acoustic panels. Our Corner Bass Traps have a trapezoidal footprint to allow for a snug fit installations into corners. (You will need at least 16" of room from each side of the corner.) Our corner traps do not have a plywood backing, but their longer sides provide more than enough structural support to allow for a flow through back which provides additional low frequency absorption.
