Description
With added technologies for 2025, the Dunlop SX 300 will give players greater access to spin and power. This racquet is perfect for players with long attacking swings, looking to crank winners with pin point accuracy.
SONIC CORE WITH INFINERGY - Allows players to hit hard with increased rebound and decreased vibration. We call it controlled power. Sonic Core, located on both sides of the racket head, provides superior rebound and up to 37% reduced vibration.
SPIN BOOST XT GROMMETS - A dynamic set of spin-enhancing grommets at the top of the racket, work with the spin boost string tech pattern to offer more spin, power and control. They allow more string movement in the direction of the arrows shown on the racket. This movement helps generate more spin. The extra movement makes the string bed more forgiving, effectively enlarging the sweet spot.
SPIN BOOST STRING TECH - The string grid area has been increased by 22% by making the main strings 10% wider and the cross strings 11% wider. This results in greater string movement allowing more power and spin generation.
SPIN BOOST FRAME GEOMETRY - Increases the level of power with increased racket stability, and a new Vibroshield dampening material. The changes come thanks to the new geometry’s mold and stiffness. The updated frame stiffness in the throat and face allows for increased stiffness by 3% and 7%, respectively
VIBROSHIELD - The high elasticity properties of the vibration dampening material within the racket frame reduce vibrations and gives an increased feeling of control when hitting.
V-ENERGY SHAFT - A unique V shape frame geometry in the shaft area of the racket, greatly enhances frame stability and racket power.

Technologies
Sonic Core Technology with Infernergy
A super elastic material, with the benefit of being very light; the perfect match to meet the demands of the modern player. It is located at 2 and 10 o’clock areas of the racket, dampening impact shock and reducing frame vibrations by up to 37%, resulting in a more comfortable hitting sensation and a reduced chance of injury.
Spin Boost + Grommets
A dynamic set of spin-enhancing grommets that work with the Spin Boost String Technology pattern to offer players more spin, power and control. The grommets allow more string movement, which creates ‘bite’ on the ball, thus generating a spin rotation. The extra movement makes the string bed more forgiving, effectively enlarging the sweet spot.
Spin Boost String Technology
An innovative enlargement of the string bed that creates more even power distribution and spin generation.
V-Energy Shaft
A unique V shape frame geometry in the shaft area of the racket, greatly enhances frame stability and racket power.
Vibroshield
High-elasticity vibration dampening layer in the shaft area filters out vibrations, giving players a less stiff, more flexible feeling.
