Woofer - The Essence of Babolat
Patented innovation by Babolat. Woofer is the first dynamic system which makes the frame and the strings interact when striking the ball.

A tennis racquet is a frame with strings

The frame is basically static and holds the driving force of the racquet - the strings - in place.  Today the way the strings are attached to the frame limits the performance of this driving force. 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.
  • This gives you a greater sweet spot and better control.
Piston Function
  • Increase the trampoline effect.  This gives you more power and increases string life.
  • Shock absorption: the pistons act like a suspension system to damp vibrations and make the racquet more comfortable to play with
Active Cortex - Vibration Dampening
Interface Between the Handle and the Frame

These two parts of the racquet are actively linked by the Cortex Damping system which filters and dampens the unwanted vibrations that don't interfere with feel.  This results in the feel of a clean hit.
GT Technology
This is a braid of special fibers with the normal graphite to make a stronger material.  The stronger material permits designers to make a racquet with more control, feel, and a bigger sweetspot.
Aero Modular
The Babolat Aero series of racquets (Aero Pro Drive, etc) use Aero Modular construction. The sides of the racquet are more aerodynamic so it moves through the air faster.  Your swing is faster with an Aero Modular racquet. Faster swings give more power and more spin. Raphael Nadal uses an Aero racquet.
Pure Strike Technologies
New PEBAX® material in grommets give extra smoothness and more power.
Different thicknesses of the beam for less torque at ball impact and better responsiveness.
New frame cross section shape increases the sweetspot by 10% to bring forgiveness on off-center hits.
Stabilizer technology is a hybrid frame construction using a stiff carbon fiber in the yoke area for improved torsional stability at ball impact to make precise shots.
Flex Carbon
New specially developed lighter, more flexible carbon fiber construction for both strength and flexibility.  Used in 2014 Pure Control series.   Racquets are also stiffened with GT technology in critical places.
FSI (Frame-String Interaction) Technology
FSI Technology provides more feel and control.
  • New Woofer system brings more feel with each strike of the ball
  • Tighter string pattern in sweetspot area
  • Higher sweetspot positioned where you hit the ball
