Head LiquidMetal
Developed by the California Institute of Technology (CalTech), LiquidMetal® alloy provides 29% more power than Titanium. Just as its name implies, LiquidMetal® alloy is different from conventional materials because of its liquid (or "amorphous") atomic structure. This means that LiquidMetal® alloy does not deform on impact, resulting in ultimate energy return.
Head places LiquidMetal® at four strategic areas of the racquet's head, integrated in the main layer of the frame's construction. This allows all of the energy from ball impact to be used for a power return - so what a player puts into his or her swing is exactly what they get out. The result is what Head calls Pure Energy. Perfect Power™
Integrated String Dampener (ISD)
Affixed to the grommets at the base of the head, the (ISD) absorbs string vibration. Now even the most powerful racquet is easy on the arm and completely comfortable, no matter what style of play.
Total Sweetspot Construction
Total Sweetspot Construction increases torsional stability in the racquet head and extends the sweetspot throughout the entire racquet head, resulting in ultimate control.
Head Intellifiber
Intelligence Technology
FEATURE: Intellifiber is a new fiber created from piezoelectric material. Extraordinarily different from conventional materials, this fiber (according to Head) transforms the mechanical energy from ball impact into an electrical response that stiffens the racquet for ultimate power. Intellifibers are integrated on both sides of the throat area. An electrical impulse actively changes the shape of the fibers - in less than a millisecond - at ball impact.
BENEFIT: According to Head, in less than the first millisecond of ball impact, Intellifibers stiffen and reduce bending in the throat area for unmatched power in current racquet design. Unlike mechanical energy, electrical energy does not create vibrations. Therefore, 20% of the vibrations are immediately eliminated upon ball impact for optimum comfort.
Head Titanium Tennis
FEATURE: A composite weave of ultra-strong titanium and ultra-light graphite fibers which help with weight reduction, while maintaining stiffness and power.
Head XtraLong
XTRALONG Technology
FEATURE: The titanium/graphite composite makes it possible to lengthen the racquet while maintaining a low swing weight.
BENEFIT: Greater reach and leverage.
Head Twin Tube
FEATURE: The inner hard shell of TwinTube technology is made of pure graphite. The outer shell consists of soft, absorbing polyamide.
BENEFIT: Increased ball acceleration combined with better, overall racquet feel.
Head SofTac Grip
FEATURE: Soft elastomer compound and traction surface construction for increased feel and tact.
BENEFIT: Prevents unintentional twisting of the racquet in a players hand. Also provides additional vibration dampening and perspiration absorption
Head IntelligenceX
FEATURE: Intellifiber is a new fiber created from piezoelectric material. Extraordinarily different from conventional materials, this fiber (according to Head) transforms the mechanical energy from ball impact into an electrical response that stiffens the racquet for ultimate power. Intellifibers are integrated on both sides of the throat area (Intelligence Technology) and now also in the racquet head, at the 10 and 2 o'clock positions (IntelligenceX Technology). These "Xtra" Intellifibers promote added stability. An electrical impulse actively changes the shape of the fibers - in less than a millisecond - at ball impact.
BENEFIT: According to Head, in less than the first millisecond of ball impact, Intellifibers stiffen and reduce bending in the throat area for unmatched power in current racquet design. Unlike mechanical energy, electrical energy does not create vibrations. Therefore, 20% of the vibrations are immediately eliminated upon ball impact for optimum comfort.
NoShox Dampening System
A newly developed "memory foam" integrated into the racquet handle reduces vibrations 27 percent better than systems in conventional racquets.
Head Protector System
The HEAD Protector Midplus and Oversize racquets feature an Electronic Dampening System (EDS). Unlike conventional dampening systems, HEAD's EDS is an active and electronically controlled system. In an EDS racquet, high-tech piezoelectric fibers convert mechanical energy into electronic energy and are controlled by a microchip. HEAD's EDS recognizes the dampening mode and electronically creates a canceling counter vibration. This reduces shock impact by more than 50% and residual vibrations twice as fast as in a conventional racquet period. This results in significantly reduced stress on the arm with each and every shot.
