Corners are the acoustician’s best friend. Walls and ceiling act as wave guides that drive energy into the corner where maximum pressure is created. The Primacoustic Corner Impaler is designed to work with 24 inch x 48 inch (60.96cm x 121.92cm) Broadway Broadband absorbers to provide effective absorption in this critical zone by combining this high-density glass-wool panel with a deep 17 inch (43.18cm) cavity to deliver effective bass control.
