Siux Fenix Pro 4

Technologies

Pros

• ✓The 18K Textreme carbon face delivers a crisp, direct response on smashes and vibora, transferring nearly all the shot's energy with barely any perceptible flex. The EVA Hard core resists trampoline effect on fast counter-attack balls, letting you finish points down the line without losing placement. The 3D grain texture grips the ball on spin-heavy shots, which really shows up on cut bandejas and topspin viboras aimed at the glass. The 38mm frame profile gives you stiffness without turning brittle, soaking up part of the impact on blocks near the net. Dual Pro Grip keeps your handle grip locked in through long rallies, cutting down on slippage once your hands get sweaty deep into the match.

Cons

• ✗The head-heavy balance and weight pushing toward 375g demand early prep on defence — arrive late to the ball and you'll pay for it more than you would with a round-shaped racket. The firmness of the EVA Hard core transmits vibration on off-centre hits, something you may feel in the elbow after a few sets back to back. Its power-first profile punishes players with a short swing on the wall exit, forcing them to adapt their technique to avoid losing depth.

The Siux Fenix Pro 4 is one of the standout attacking rackets in Siux's lineup: diamond shape, 18K Textreme carbon face and EVA Hard core, weighing in between 360 and 375 grams.

18K Textreme Carbon Meets EVA Hard: The Combo Behind Its Punch

The face is built from 18K Textreme carbon, a high-stiffness fibre weave that barely deforms on impact. Paired with a high-density EVA Hard core, the racket prioritises direct energy transfer over shock absorption. The 38mm frame profile holds its rigidity without turning brittle on off-centre hits.

The 3D grain texture etched into the face isn't just for looks: by gripping the ball harder at the point of contact, it favours shots with spin, which translates into cut bandejas with extra bite and viboras that climb off the glass with more rotation.

Smash, Bandeja and Vibora: How It Performs When You're Closing Out Points

On the smash, the diamond shape and head-heavy balance concentrate weight up near the head, and it shows on winners down the 3 and 4: the racket arrives with more head speed than an equivalent round or teardrop racket. On bandeja and vibora, the EVA Hard core responds with minimal deformation, so the ball comes off fast even on counter-attack shots where there's no time to follow through.

The Dual Pro Grip operates on a different level entirely: it doesn't change the power, but it keeps your handle grip steady through long matches, which matters when heat or nerves get your hands sweating in the third set.

The Trade-Off for All That Power: Defence and Wall Exit

The flip side of a head-heavy balance and a hard core shows up on defence. The wall exit demands a longer, earlier-anticipated swing than you'd need with a control racket, because the effective sweet spot sits further from the racket's centre compared to a round-shaped model.

What Level Is the Siux Fenix Pro 4 Built For?

Siux positions it at advanced level, within its attacking range. This is not a beginner or club-level racket: the weight pushing toward 375g and the core's firmness punish anyone who doesn't bring enough arm speed into the shot, while rewarding players who already close out points consistently from the back of the court.

Who Should (and Shouldn't) Play With the Fenix Pro 4?

Good fit for: - Advanced players with an attacking game, comfortable smashing and finishing down the 3. - Players after a racket that doesn't bleed energy on blocks and smashes. - Players already used to head-heavy rackets who don't need extra help on defence.

Not a fit for: - Players dealing with elbow or forearm issues, given the EVA Hard core's limited shock absorption. - Short-swing players or those with slow prep, who'll struggle on the wall exit. - Anyone after an all-round racket that switches between attack and defence without a penalty.

Verdict

The Siux Fenix Pro 4 is a pure attacking racket: 18K Textreme carbon, EVA Hard core and diamond shape built to maximise power on the smash, bandeja and vibora. Its biggest strength is sheer punch on finishing shots; its biggest drawback is a lack of forgiveness on defence and for arms without a solid physical base. Recommended for advanced players with a settled net game and smash, not for anyone still working their way up in level.

How Much Does the Siux Fenix Pro 4 Weigh?

The Siux Fenix Pro 4 weighs between 360 and 375 grams. That's a medium-high weight among power-oriented diamond rackets, consistent with its head-heavy balance and 38mm frame profile.

Is the Fenix Pro 4 a Control or Power Racket?

It's a power racket, according to Siux's own classification. The diamond shape, head-heavy balance and EVA Hard core prioritise punch on the smash and finishing shots over defensive control, unlike round or all-round-oriented rackets.
