What players say
Reviewers agree the 2025 SX 300 is Dunlop's spin machine: the enlarged Spin Boost XT grommets and open 16x19 pattern make heavy topspin very easy to produce, and the reworked hoop adds stability versus the previous version. The tradeoffs are a firm, somewhat muted feel and a high launch angle that can hurt depth control and touch shots.
Best for
- Aggressive baseliners who brush up on the ball
- Players wanting easy topspin and depth
- All-court players who want a stable, forgiving frame
- Pure Aero style swingers looking for an alternative
Pros
- Very easy, heavy topspin generation from the open string pattern and wider grommets
- Accessible power with good depth on groundstrokes
- Maneuverable and stable for a 100 sq in spin frame
- Improved lateral stability at 3 and 9 o'clock versus the prior SX 300
- Spin also helps second serves and kick serves land safely
Cons
- Firm, muted feel at the throat that isn't ideal for touch or feel players
- High launch angle can cause overhitting and inconsistent depth control
- Harder to flatten out put-away shots or drive low passing shots
- Slices can float when aimed at ambitious targets

The SX 300 was a really easy racquet to swing from the baseline. I was able to generate a lot of spin thanks to its open string pattern.

Easy spin and power were still the main features. The string spacing is quite open, which led to a pretty high launch angle.

The SX 300 lives up to its name, and spin was the highlight of the playtest for me.

This was a great hitting experience, and I thought the racquet was easy to pick up and play with.
