Kinetic System Technology
Kinetic Classic: This is the original Kinetic Technology. It feature thousands of micro-bearings housed inside multiple chambers surrounding the entire 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.
Ki (Kinetic + Ionic): This is the second generation of the Kinetic System. It uses an Ionic coating process to alleviate all static electricity to fully optimize the dynamic power of the micro-bearings. The result is MORE power, MORE Stability and MORE comfort.
Ki Quadfocus (Kinetic + Ionic + Quadfocus): This third generation of the Kinetic System includes the Ionic coating process but also concentrates the location of the Kinetic chambers in only four compartments around the head: 10 & 2 and 8 & 4 o'clock. By relocating the secondary mass to less stable regions of the frame, ProKennex has created a more solid feeling racquet, one that better deploys the arm saving properties of Kinetic Technology.
With the introduction of the Q+ Series in 2017: ProKennex improves Quadfocus Technology by expanding the Kinetic Energy Chambers by 25%! The result is even more vibration dampening along with greater torsional stability and shock reduction (according to ProKennex). Also with the Q+ Series ProKennex updated the frame chassis with a QShape to expand the sweetspot, representing a high performance output over a larger surface area.
