The Q 15 utilizes Q Engineering which focuses Kinetic technology at the four corners of the racquet for maximum Kinetic Effect resulting in greater power, spin potential, torsional stability on off center shots and reduced vibration for increased comfort.
A strip of pods containing hundreds of tiny lead bearings is incorporated inside of the racquet frame during production. If you shake the racquet it sounds almost like sand inside the frame. This strip creates a secondary energy source, reduces shock & dampens vibration, and provides exceptional torsional stability. Simply put Kinetic is better shots, more often, with less pain!
QuadFocused: Pro Kennex "componetized" the Kinetic housing into segments and located them in the four corners of the frame. By concentrating the entire secondary mass in these four locations, maximum kinetic effect is dynamically activated. Q Engineering also allows the system to be tuned for better leverage swing physics delivering unprecedented frame performance with both spin and power; 15% increase in power zone, 50% improvement of torsional stability on off center shots, 43% reduction of vibration and the only technology proven to eliminate shock.
