Energy Box and Energy Shaft

Energy Box and Energy Shaft beam construction work together to deliver enhanced racquet head stability and a more powerful response by increasing beam stiffness in key areas.

Energy Box
Located at the 5 & 7 o'clock positions on the racquet face, the Energy Box is supported with Titanium and Lite Carbon. This material mix along with the box shape construction is designed to increase stability in the racquet. On off-center shots, the Energy Box works to stabilize the racquet for smoother and more precise shot making.

Energy Shaft
The unique triangle shaped shaft construction was developed for one reason: POWER. The Energy Shaft stiffens the shaft area of the racquet, resulting in less energy loss and hence adding more power to every shot.
