LARGE Custom Built 4" Acoustic Sound Panels Bass Traps

LARGE BASS TRAPS Increase speech intelligibility. Stop unwanted noise. Helps lower overall noise levels. Fabric wrapped Acoustical Wall Panels are a perfect solution to any unwanted noise problems (ESPECIALLY LOW END FREQUENCIES) in a studio, home theater, gymnasium or house of worship. Choose your custom size and color to fit your environment.  IMMEDIATELY INCREASE BASS INTELLIGIBILITY – In addition to controlling all of the mid and high frequencies that a 2" panel would cover, the 4" version takes absorption further by taming lower frequencies heard in a kick drum, bass guitar and/or subwoofer. MORE THAN PERFECT SOUND ABSORPTION: NRC 1.1 out of 1. –  We recommend covering at least 15-20% of a room’s wall space for effective sound control for normal indoor environments (30-45% in problem areas). HUGE SELECTION OF COLORS AND SIZES – Mix and match bass traps to find the exact configuration of colors and shapes that will complete the acoustic wall treatment to your specifications.
