Price
Approx. €300–€340
Approx. $320–$360 USD
Market positioning: Premium / Pro
Realistically for: Advanced competitive players looking for a power-focused tournament frame
This sits in the premium performance category. It is designed for serious competitors rather than casual players.
Weight & Balance
Listed weight: 360–375g
On-court balance feel: Head heavy
Physical demand level: High
Fatigue factor over long matches: Noticeable
The high balance is immediately apparent. It provides strong momentum on overheads but demands strength and conditioning. In long matches, particularly for players over 40, shoulder fatigue can accumulate.
This is not a light or forgiving setup.
Shape
Diamond
Natural bias: Offensive
Sweet spot location: High, near the tip
The high sweet spot rewards aggressive positioning and contact taken above shoulder height.
Materials & Construction
Face material: 21K Twill Carbon
Core type: EVA (Pro rubber, firm density)
Frame composition: 13K Carbon with Aramid reinforcement
Surface texture: 3D rough finish
How materials translate into feel
The 21K carbon face produces a hard, compact sensation at impact. Combined with the firm EVA core, the response is crisp and explosive rather than cushioned.
The aramid reinforcement adds structural stiffness and durability. Overall, the racket feels solid and uncompromising.
Sweet Spot & Forgiveness
Sweet spot size: Medium-small
Off-center stability: Good structurally, but not forgiving
Margin for error under pressure: Limited
The sweet spot sits high and rewards clean contact. Off-center hits feel firm and lose depth quickly. Players must be technically consistent.
This is not a racket that hides mistakes.
Maneuverability
Speed in hand: Moderate
Net exchanges: Stable but not quick
Reaction defense: Demanding
Defense → attack transition: Powerful when prepared
The head-heavy balance slows reaction speed slightly compared to lighter rackets. However, once set, it transitions strongly into attacking shots.
Players accustomed to diamond rackets will adapt more easily than those coming from round shapes.
Feel
Hard
Dry and direct
Very clear feedback
Comfort level: Low to moderate
The feel is firm and uncompromising. Feedback is precise and immediate, which advanced players appreciate for aggressive play.
However, for players managing elbow or shoulder discomfort, this setup can feel demanding over time. It is not built primarily for vibration absorption.
Power
Overhead power: Very strong
Smash potential: High
Vibora / Bandeja performance: Penetrating and aggressive
Power generation: Rewards full commitment
This is where the Fenix Pro 4 stands out. The high balance and stiff carbon deliver heavy ball output on flat and kick smashes.
It does not produce effortless power without proper swing speed—but when you commit, the result is authoritative.
Control
Directional accuracy: Good when struck cleanly
Defensive precision: Adequate but demanding
Reset capability: Limited assistance
Touch play: Direct but not soft
Control is solid in active attacking play. In defensive resets, the firm core offers less rebound help, requiring stronger technique.
Touch shots require a soft hand due to the firm face.
Defense
Back glass recovery: Requires preparation
Stability under pressure: Structurally solid
Ease of lifting lobs: Technique-dependent
Defensively, this racket is workable but not effortless. Lifting deep lobs requires good timing and acceleration. The stiff construction does not provide much free lift.
Final Verdict
The Siux Fenix Pro 4 2024 stands out as a true attacking diamond built for players who want firmness, structural stability, and heavy overhead performance. It is not designed to be forgiving or comfort-oriented—it is built for decisive, aggressive play.
This racket truly fits advanced competitors who are physically prepared and technically consistent. Left-side attackers who rely on smash pressure will appreciate its response.
At its premium price, it delivers performance in its intended category. However, for 40+ and 50+ players prioritizing arm health and fatigue management, it may feel demanding over long matches.
