Solid resonance and feel on impact, the hallmark of the famous Carbonex Series' Box Shape, continue to make these powerful racquets favorites among many top pros. The Box Shape construction suppresses twisting on impact for more power and accuracy.

Carbonex series racquets has stiff and powerful box construction for high power and consistent control that has made Carbonex Racquets the long-time favorites of hard hitters. Carbonex series racquets are famed for durability and low-torque performance springing from the strong box-like cross section and patented Yonex Built-in T-Joint, which functions to provides a consistently stable hitting surface for power and control. The Yonex patented Built-in T-joint transmits the full energy from the shaft to the frame then to the shuttlecock.

At impact, the area where the shaft and frame are connected is subjected to an enormous stress load. If left unchecked, a racquet's power is loss and control diminished through distortion. Moulded deep into the layers of graphite where the frame connects with the shaft, the Yonex Built-in T-Joint creates a durable and high-strength one-piece frame that is torque-free. The patented construction results in more power and more accuracy smash after smash.
