The frame is basically static and holds the driving force of the racquet - the strings - in place. The strings are attached to both sides of the frame. Only some strings are active when struck by the ball. This means that racquets do not deliver their full potential. Babolat set out to imagine a racquet optimizing the frame and the strings - to invent a frame which permits all the strings to work together to their full potential when striking the ball.Pulley Function:The WOOFER eliminates string lock-up: the strings are free to move.The whole surface area reacts on impact: with the WOOFER, more strings work together when striking the ball. The strings are interactive. This increases sweetspot size, improving forgiveness during off-center shots and absorbing much of the shock produced during ball impact.
