The new black and green beast known as the Dunlop SX utilize SPIN BOOST grommets at the top of the head, which allows the main strings to slide 46% more in a specific direction to help increase ball rotation and power outside of the sweet spot.
And there’s help even if you aren’t quite making perfect contact: The technology touts greater control and spin potential even when missing the sweet spot. Sonic Core Technology with Infinergy was introduced with the CX series and now is continued onto the SX series for a more comfortable flex.
Across the entire SX racquet line, there’s a slightly expanded cross section of 23/26/23 MM giving you easier access to power. Another intriguing feature is located on the shaft just below the head where grooves in the graphite maintain stability, but also offer a more aerodynamic performance, similar to what you see on the Babolat Pure Aero. Let’s dive deeper into Dunlop’s newest series to help you determine which frame is best for your game.
SX300 Tour: offers more flex, control and stability than any other frame in the line, but will be a little harder to maneuver. Comes in at 10.9 ounces, unstrung.
SX300: The SX 300 is going to be easier to swing through the air (10.6 ounces unstrung) and has enough mass to redirect hard shots effectively. Though stability may not be as strong, it can easily be customized to your liking.
SX300 LS: The SX 300 LS offers a slightly firmer flex rating of 68 and weighs just under 11 ounces strung (10.8 oz). Though it comes in a little higher on the RA scale, it’s still going to feel very comfortable thanks to Dunlop’s Sonic Core and Power Grid technologies. The 300 LS is a lighter, more maneuverable racquet than the 300 or 300 Tour but still offers excellent stability for a lightweight frame.
SX 300 Lite: At 9.5 ounces unstrung, making it easy to generate racquet head speed and remain mobile everywhere on the court.
SX 600: The most unique frame in the SX lineup is the SX 600.It has a light unstrung weight of 9.5 ounces, but has a slightly wider beam of 23-26.5-23 millimeter for easier power and stability. The SX 600 also comes with a slightly longer length (27.25 inches) and larger head size (105) for effortless spin as well as ball speed generation.
