It fits inside the drum, acoustically dampening the internal reflections from its shell, while physically dampening any additional harmonics from the drum's front and rear skins. The panel's density and multi-cavity design help create the right attack and control the sound of the kick drum without compromising its "character". Panel is designed to fit any size of bass drum. Panel dimensions: 620 x 620 mm.
