While adaptable acoustics are common, Manta explores new levels of continuity and responsiveness, advancing acoustic systems beyond individual elements and corrective treatment. Manta is comprised of CNC machined panels and connectors of two thicknesses of high density polyethylene, and curved forms result from a combination of triangulation and bending stiffness: geometry and material in concert. The result is a controlled morphing that is suspended at a minimum of points. Manta was designed and fabricated as part of Smartgeometry 2012 to utilize the rigging infrastructure and acoustically inert environment of Rensselaer Polytechnic Institute’s Experimental Media and Performing Arts Center.
