The Dunlop SX 300 LS Tennis Racquet gets a dynamic yellow and black cosmetic for 2022. The SX models are Dunlop`s most spin-friendly frames, and the brand builds on that reputation with some updated game improvement tech. Sonic Core Technology with Infinergy returns has been placed at the 10 and 2 o`clock positions for greater rebound and vibration dampening. The SX 300 utilizes the brand`s new Spin Boost String Technology. The cross-string spacing in the center of the racquet has been reduced to provide greater control, while the upper hoop benefits from a more open spacing for greater forgiveness, spin, and power.
