The Dunlop Srixon CX400 pairs the lightest CX model with the largest head size and thickest beam to allow easier power generation.
Play a better game with the CX 400’s fusion of power, control and spin. This is the lightest CX model and has the largest head size. So players can generate easy power. Ideal for players looking to improve their game.
Designed to help produce more spin, the new CX400 uses Dunlop-Srixon's new PowerGrid StringTech. This gives you a 30% larger sweet spot compared to other tour-level rackets, allowing to get more control, power, spin and consistency than before as your power is evenly distributed across the string bed.
Complimenting the new string-bed technology is the new Aero-Box frame design. By using a new type of frame geometry, the CX400 allows to hit shots with more power, control and comfort thanks to the recognisable thinner front edge. This enables more frame compression, which in turn enhances your sweet spot further, while the aerodynamic frame shape features sharper angles and cuts through the air to let you play faster, cleaner shots.
The CX400 also offers fantastic comfort and flex for players with a revolutionary new dampening technology, Sonic Core. By partnering with BASF, Dunlop-Srixon have brought BASF's world-leading Infinergy technology to tennis rackets, which reduces frame vibrations by up to 37% and provides fantastic energy-returning performance for you as the game progresses, allowing you to maintain your performance levels with ease as your opponent tires. Already made famous through its use under the name 'Boost' in running shoes, BASF's Infinergy foam offers absolutely fantastic performance and comfort for tennis players, reducing the risk of developing injuries considerably, while allowing you to hit with increased ball speed and ball height.
Ultimately, this results in a tennis racket that offers you fantastic, versatile performance to help you add more spin, power and comfort into your game while giving you the very latest in racket innovation, making the CX 400 a uniquely brilliant tennis racquet.
Dunlop-Srixon Technology
PowerGrid StringTech - Modern players use more spin, hitting the ball towards the top of the racket. But that takes technique and power, often leading to errors and injuries. PowerGrid StringTech creates a 30% larger sweet spot, evenly distributing power across the string bed. Get better control, more power and more spin.
Sonic Core, made with Infinergy by BASF - Play harder, cleaner shots. Sonic Core, made with Infinergy dampens impact shock and reduces frame vibrations by up to 37%, giving a more comfortable hitting sensation. Infinergy foam developed by BASF, the world's first E-TPU, offers much greater rebound properties compared to the original Sonic Core materials.
New Frame Geometry - Play shots with more power, comfort and control thanks to a thinner front edge, enabling more frame compression which enhances the sweet spot. This modern aerodynamic frame shape features sharper angles and cuts through the air to hit a faster, cleaner shot.
