Dunlop adds another chapter to the CX 400! Like the previous generation, this update pairs a powerful 24mm beam with a 16x19 string pattern. It also packs a sub-315 swingweight, making it easy to maximize stroke speed when loading the ball with pace and spin. For this update, Dunlop retools the beam, adding more of a box shape below the 10/2 axis to enhance stability, control and feel. Additional changes for 2024 include Powergrid Stringtech+, which features wider cross-string spacing to enhance spin and power. Dunlop also updates the stiffness profile, adding greater flexibility on the inner part of the frame for enhanced dwell time and pocketing, while also stiffening the racquet's face for added stability and power. To help reduce harsh impact vibrations, Dunlop adds a highly elastic material (named Vibroshield) to the midsection of both the hoop and shaft. This is complemented by Sonic Core with Infinergy, a uniquely pliable material applied to the 3/9 axis of the head to boost comfort and power.  Ultimately, this update to the CX 400 is a great option for intermediate players looking for a speedy and spin-friendly weapon with enough power to close out points.
