XeneCore is a new fiber technology that uses high-pressure solids to form and reinforce the graphite fiber composite to incredible levels of strength that has allowed Donnay designers to reduce the thickness of the racquet beam width to a dramatic 15 millimeters, the thinnest in tennis. The thin beams greatly reduce air resistance (the same reason that sleek sports cars outperform bulky SUVs in wind-tunnel tests) providing unparalleled levels of maneuverability. The high-tensile strength of XeneCore also dampens vibration and provides unexpected power, while reducing the "shadow effect" from the beam blocking a portion of the string bed on off-center hits resulting in "frame shots." The net result of XeneCore technology is a previously unachievable level of all-around performance.
Hexagonal molding is a manufacturing process that incorporates 10 hexagonally shaped string holes on each side of the racquet frame during the molding process. The X-Series Black, Blue and Dark Red models use this technology that allows tournament-level players to generate maximum spin due to increased torsional rigidity, resulting in a firmer feel. The hexagonal holes also make the racquets play slightly stiffer than their RA (machine) ratings that provides exceptional power.
