Aquarian FR20BK Force II 20" Black Rezonansinė būgno membrana

The Full Force™II  (FRBK)  Black, single ply, medium weight Resonant bass drumhead features a “vented” acoustic muffling ring tucked into the hoop on the underneath side of the head. The muffling ring helps control overtones and features vent holes along its perimeter that allow the ring and head to move as one. Available in both White and Black Translucent, Reverse Painted Video Gloss. The Video Gloss finish helps to dry out the head just a bit, making for warmer resonance with a pigmented translucent appearance. A FREE PortHole™ is included with every Full Force II head and allows the drummer to place a 5" vent hole in a desired location.
