The Dunlop Sport FX 500 (in its signature Blue/Black cosmetic) is Dunlop’s flagship power and spin frame. Positioned in the same high-octane 100 sq. in., 300g category as the Babolat Pure Drive and Yonex EZONE 100, it combines explosive ball speed with aerodynamic speed and surprising comfort for a stiff power racquet.
Performance Profile
- Explosive Power & Depth: Built with Power Boost+ Frame Geometry—a wider aerodynamic beam profile and broader throat area—to maximize energy transfer and create easy depth with minimal swing effort.
- Vibration Dampening & Feel: Integrates Sonic Core technology with Infinergy® (by BASF) placed at the 2 and 10 o'clock positions in the head. This foam material dampens harsh impact shock while boosting rebound speed, resulting in a cleaner, less jarring feel than older stiff power racquets.
- Enlarged Sweet Spot: Utilizes Power Grid String Tech and wider main string spacing across the center to create a forgiving, high-launching sweet spot that keeps off-center hits competitive.
- Fast-Swinging Speed: With a 7-point head-light balance, it maneuvers rapidly through the contact zone, making it easy to generate heavy topspin RPMs or react quickly at net on volleys.
Best Suited For
- Intermediate to Advanced Players: Hitting strong groundstrokes and looking for a lively, high-powered frame that drives opponents deep behind the baseline.
- Aggressive All-Court & Baseline Attackers: Players who like to dictate points with big serves, fast forehands, and heavy topspin.
- Pure Drive / EZONE Alternatives: Anyone seeking the free power and fast acceleration of a modern 100 sq. in. frame with a slightly softer, dampened feel on impact.
