Dunlop SX300 Limited Black Tennis Racquet

Dunlop SX300 Limited Black Tennis Racquet – Easy Spin & Aggressive Power

The Dunlop SX300 Limited Black Tennis Racquet is engineered for players who want to make spin a genuine weapon. Designed for aggressive modern tennis, the SX300 combines easy access to heavy topspin, controllable power, stability, and forgiveness to help you dictate rallies from anywhere on the court.

Featuring a 100 in² head size, 16x19 string pattern, and a fast 320 mm / 7 pts head-light balance, the SX300 provides an excellent combination of spin potential, maneuverability, and control. Advanced Spin Boost XT Grommets, Spin Boost Frame Geometry, Spin Boost String Tech, V-Energy Shaft, Vibroshield, and Sonic Core with Infinergy® by BASF work together to maximize spin while maintaining a comfortable and confidence-inspiring response.

Easy Spin Generation

The SX300 is designed to make generating heavy spin easier. Its spin-focused technologies increase string movement and snapback, helping the strings grip the ball and produce greater rotation. The result is heavier topspin that can dip aggressively into the court and kick higher after the bounce.

Spin Boost XT Grommets – Maximum String Movement

Spin Boost XT Grommets feature enlarged and angled grommet holes designed to allow greater string movement. Increased string movement helps enhance ball bite and snapback, creating more spin potential and a larger, more forgiving sweet spot.

The optimized grommet design also helps produce different ball trajectories depending on where contact occurs, supporting higher launch and increased topspin on higher-face impacts while helping create deeper shots on lower-face contact.

Spin Boost Frame Geometry – Enhanced Stability & Spin

Spin Boost Frame Geometry features a redesigned frame shape engineered to improve stability and racket-face control at impact. The wider frame profile and increased center rotation inertia help reduce twisting on off-centre hits while maintaining a consistent response during aggressive swings.

The result is greater stability, more consistent ball flight, and the confidence to accelerate through the ball while generating heavy spin.

Spin Boost String Tech – Spin & Control

Spin Boost String Tech uses an open string configuration to encourage greater string movement, making it easier to generate spin and power. Tighter spacing through the centre of the string bed helps maintain directional control and shot precision.

This combination allows players to swing aggressively while using heavy spin to keep powerful shots inside the court and create greater margin over the net.

V-Energy Shaft – Enhanced Spin, Power & Stability

The V-Energy Shaft features a unique V-shaped design engineered to increase frame flex and enhance ball pocketing. The responsive shaft helps the strings stay connected with the ball for longer, supporting greater spin generation while providing easier access to power and improved shot control.

Sonic Core with Infinergy® by BASF – Responsive Comfort

Sonic Core with Infinergy® by BASF is strategically positioned at the 2 and 10 o'clock areas of the racket head to improve energy return and responsiveness. The highly elastic material helps transfer more swing energy into the ball, providing easier access to pace and spin.

Its vibration-absorbing properties also reduce unwanted feedback at impact, creating a cleaner and more comfortable feel that allows players to swing aggressively with greater confidence.

Vibroshield – Smoother Feel & Comfort

Vibroshield incorporates an advanced vibration-dampening system designed to reduce unwanted shock at impact. The highly elastic material helps filter harsh vibrations, providing improved comfort, cleaner feedback, and a smoother response on every shot.

Forgiving Sweet Spot – Confidence Under Pressure

The SX300's 100 in² head size and spin-focused frame technologies create a generous and forgiving hitting area. The larger sweet spot helps maintain power and consistency when contact isn't perfectly centered, giving players more confidence to swing freely during demanding rallies.

Built for Aggressive Baseline Tennis

The SX300 is designed for intermediate to advanced players who want to attack with heavy topspin while maintaining control. Its combination of spin, power, stability, and forgiveness makes it ideal for pushing opponents behind the baseline, creating sharper angles, and producing passing shots with confidence.

Who Is the SX300 For?

The Dunlop SX300 Limited Black is ideal for players who want easy access to spin without having to completely change their technique. It is particularly suited to aggressive baseline players who use heavy topspin to create depth, angles, net clearance, and pressure.
