According to ProKennex the new Ionic-AKS technology offers a 56% performance improvement over the original Kinetic System. The use of a new
composite Kinetic material and a process designed to reduce the build up of
static electrical force inside the Kinetic strip adds even more power and
further reduces frame shock and vibration compared to the original Kinetic
Kinetic System Technology
Thousands of micro-bearings are housed inside chambers around the racquet head. As the racquet swings forward, the micro-bearings move to the back wall of the frame, loading energy. When the racquet strikes the ball, this kinetic mass transfers forward, adding power and reducing frame shock and vibration.
