1. Rigid material: ensures the strings' perfect skid upon impact with the ball.

2. Flexible material: captures vibrations before they propagate into the frame.

Advantages
Five times more shock-absorbing than a traditional bumper grommet! From now on, racquets with oversized heads are both powerful and comfortable. Dual Woofer will provide unparalleled comfort and excellent feel.

A tennis racket is a frame with strings. The frame is basically static and holds the driving force of the racquet - the strings - in place. The strings are attached to both sides of the frame. Only some strings are active when struck by the ball. This means that racquets do not deliver their full potential. Babolat set out to imagine a racquet optimizing the frame and the strings - to invent a frame which permits all the strings to work together to their full potential when striking the ball.

Pulley Function
The WOOFER eliminates string lock-up: the strings are free to move. The whole surface area reacts on impact: with the WOOFER, more strings work together when striking the ball. The strings are interactive. This increases sweetspot size, improving forgiveness during off-center shots and absorbing much of the shock produced during ball impact.

Piston Function
Increase in the Trampoline Effect: The piston function enables greater surface deformation on impact, delivering 10% extra power and ensuring that the strings retain their energy for a longer time.

Shock Absorption
The pistons act like a suspension system to dampen unwanted vibration.

With a conventional racquet, the ball strikes the racquet at 90 degrees, but due to the racquet flexing it leaves the racquet at a different angle. A Flexpoint racquet is designed to cup the ball by flexing at the Flexpoints. The cupping effect reduces the angle at which the ball leaves the strings and promotes more accurate hitting. Flexpoint technology increases the dwell time and ball pocketing due to its cupping effect which increases feel and provides a larger sweetspot.

Flexpoints are made up of two complimentary features and are located at the 3 and 9 o'clock positions on the racquet head. Each Flexpoint features an engineered dimple to create flexibility by reducing the beam width by a maximum of 25%. Each Flexpoint also features a hole in the center of the dimple which reduces sectional stiffness by 50%.

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™

Intellifiber

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.

The internal Kinetic™ mass contained an equal number of positive and negative charges, producing an electrically balanced environment under static (non-moving) conditions.  When friction (through movement) is introduced, the tiny Kinetic™ mass elements as well as the capsule material became electrostatically charged.  The electrostatic charges exerted a tremendous force (like strong magnets) on any nearby material or objects, resulting in the clinging or repelling of the Kinetic mass particles to each other and to the capsule walls (fig.1). This electro static condition inhibited the full potential of the Kinetic™ system.

Our Scientists knew that a solution to the electrostatic charge inherent in the “machine” would effectively deliver a turbo-boost to a system that already out-performs the industry.     Ionics™ by ProKennex delivers the breakthrough in Kinetic™ science through a process using static eliminators (called ionizers) that neutralizes electro static charges. These anti-shock ionizers are electrically powered to produce a bulk of positive and negative ions. The charged surface attracts the appropriate number of positive and negative ions from the ionizer to become neutral.

Result
Complete freedom of movement within the chambers, unlocking up to 56% more efficiency to
the Kinetic™ system  (fig. 2).

When the ball hits the strings, the strings flex and the ball compresses. The ball speed drops to zero. The ball and strings are now loaded with energy. (Fig. 2)

Finally, the racquet frame flexes backward as your swing continues. Going with the flow, the ball assumes the racquet’s forward speed. (Fig. 3)

Forces are now in place to set off a scientifically calculated Kinetic™ reaction. The ball and strings now start releasing their stored energy causing the ball to go faster than the racquet. At this moment, the energy release from the ball and strings triggers the kinetic mass. It explodes forward in all 100 chambers. This activated mass joins with the mass of the racquet to increase the area of efficiency of the hitting surface and magnify the possibilities of a good shot.

Area Of Efficiency
Modern tennis moves so fast that even the pros have little time to set up. The Kinetic™ System increases your odds for great contact by freeing you from the tyranny of the sweet spot. When the Kinetic™ chambers release their stored energy it gives this energy to the racquet. This new momentum stabilizes the entire hitting surface. Your shot is more precise even if you hit the ball off-center.

Active Damping System
You know your arm feels after you’ve hit the ball?
That ripple of vibration?
The Kinetic™ System virtually eliminates this sensation. Once the ball leaves the strings, the tiny elements of kinetic mass actively damp this now-useless energy. This vibration is absorbed as it attempts to work its way through layers of active kinetic mass. The vibration energy is efficiently quieted. You’ll notice a huge reduction in wear and tear on your body and an increase in the efficiency as a player.

It's lightweight power with feel.

The Result
The player feels the ball on the strings because much of the disruptive initial shock is eliminated while the wood shapes the vibrations into information a player can use.

Benefits
Better feel of the ball on the strings, more focused energy transfer, better control, easier on the body.

ProKennex offers a “one at a time” manufacturing technique that ensures the most narrow variance possible between frames. Heritage racquets will appeal to players with advanced game styles and who put a premium on precision versus technology.

2. Control Phase - Receive Time: As the ball hits the string bed, the Catapult spring compresses and energizes or "loads" the catapult, thus creating a deeper string bed pocket. The increase in receive time (the Control Phase) results in 30% more control and a larger sweetspot.

3. Power Phase - Release Time: The explosive resetting of the Catapult shortens the release time (the Power Phase) by 30%, delivering more power. Power is further enhanced because the ball compresses less and retains more of its own energy.

There are 3 key cross-sections along the length of the racquet. These comprise 3D Power Max Frame Technology and each maintains a specific purpose:

1. The rectangular cross-section at the tip of the racquet head: this increases stiffness and adds power.

2. The kidney-shaped central cross-section: this provides a deeper string pocket upon ball impact - a feature designed to increase feel and touch.

3. The oval cross-section in the throat: promotes torsional stability.

Series H racquets establish a new standard of stability in racquet design - a full 10% more stable than competitive models. They feel rock solid. They explode with power. Ask Lindsay Davenport Todd Martin and Justine Henin. They are already Series H believers.

nCoded racquets measure 2 times stronger 2 times more stable and up to 22% more powerful than ordinary racquets.
