The RealAcoustix REALBBT is a broadband bass trap for eliminating standing waves in corners. Popular uses are for vertical corner treatments on back walls and ceiling corners. The use of broadband bass traps like the BBT should be considered carefully as it’s absorption character is “broadband” and it is capable of absorbing most frequencies 100% down to >125Hz (depending on size).
