Design and build quality of the Siux Fenix Pro 4
The reviewer opens with a strong statement: among all the Siux rackets tested over the years, the Siux Fenix Pro 4 stands out as a personal favorite, despite not being flawless. Visually, the racket is described as “so flashy it becomes beautiful,” thanks to its metallic orange and gold accents. The head shape is notably more squared compared to previous Fenix models, marking a radical design shift that makes it immediately noticeable on court.
In terms of construction, the Fenix Pro 4 features a full carbon frame with Textreme 21K aluminized carbon on the faces, giving it a premium look and feel. The surface texture is reminiscent of the Adidas Adipower series, particularly the “spin blade” technology, which the reviewer notes as a hybrid between the Adipower and Adipower CTRL models. This blend results in a racket with a distinctly aggressive character, both in appearance and playability.
- Weight range: 355–380g (tested model: 360g)
- Balance: 28 cm (very high)
- Face material: Textreme 21K aluminized carbon
- Core: EVA Hard
- Grip: ShockOut grip with lanyard
While the overall build impresses, the reviewer is critical of the ShockOut grip, describing it as uncomfortable and prone to rapid wear, especially considering the racket’s premium price point. The grip’s design, partially encased in plastic, is seen as a mismatch for a racket of this caliber. However, the handle shape itself is appreciated for its comfort and slightly pronounced butt cap.
On-court performance: power, control, and feel
Once on the court, the Fenix Pro 4 immediately reveals its power-oriented DNA. The high balance (28 cm) and hard EVA core make it a true “beast,” designed for aggressive players who thrive on attacking play. The reviewer repeatedly compares its performance to the Adidas Adipower series, noting that the Fenix Pro 4 feels even more communicative and responsive, especially in powerful exchanges.
Despite its high balance, the racket does not feel excessively head-heavy or unwieldy in the hand—at least in the tested 360g version. Heavier models (up to 375g) do feel more substantial, but the Fenix Pro 4 avoids the sensation of being a “brick.” The reviewer emphasizes that while the racket is not particularly forgiving from the back of the court, it rewards players with good technique and intention, especially those at an intermediate-advanced level or higher.
The Fenix Pro 4’s sweet spot is described as small but not tiny, and the impact is firm without being excessively rigid. Ball output requires some activation, but once engaged, the racket delivers explosive power with minimal effort. However, the reviewer warns that the energetic response can make control challenging, particularly in fast defensive exchanges or when under pressure. The racket is best suited for players who can consistently command the point and manage its lively nature.
Spin potential and shot variety
One of the Fenix Pro 4’s standout features is its exceptional spin generation. The textured face grips the ball effectively, allowing for heavy topspin and slice with excellent precision. The reviewer highlights the racket’s ability to “malleate” spin, providing a high degree of control over ball rotation without sacrificing power. This quality is particularly noticeable on aggressive wall exits, volleys, and overheads, where the racket’s surface “has teeth” and keeps the ball on the strings just long enough for maximum manipulation.
During volleys, the Fenix Pro 4 offers a solid, direct feel. It’s not the most sensitive racket on the market, but it strikes a balance between firmness and feedback, making it suitable for technical players who appreciate a crisp response. The reviewer notes that the racket is less punishing than others with similar specs, such as the StarVie Triton Pro, and is easier to maneuver thanks to a well-proportioned handle and a mass distribution that supports dynamic play.
Performance in smashes and aggressive play
When it comes to smashes, the Fenix Pro 4 truly excels. The reviewer describes it as a “hammer,” delivering flat and kick smashes with remarkable ease and power, even at medium-high swing speeds. The racket’s ability to generate force without demanding excessive physical effort is seen as a major advantage, allowing players to hit explosive winners while maintaining control. The kick smash is singled out as one of the best tested in recent years, with the ball bouncing high off the glass with minimal effort.
However, the reviewer cautions that the racket’s aggressive nature requires discipline—if technique falters or timing is off, it’s easy to send balls long or lose control, especially on fast-paced volleys or defensive recoveries. The Fenix Pro 4 is not a racket for conservative or control-oriented players; it’s designed for those who want to dominate points and finish rallies with authority.
Comfort, maneuverability, and technical notes
Despite its power focus, the Fenix Pro 4 is surprisingly manageable for its category. The reviewer finds it less fatiguing on the arm than expected, though extended play with the high balance can eventually take a toll. The grip, as mentioned earlier, is a weak point, both in comfort and durability. Additionally, the reviewer notes the presence of ShockOut dampeners in the head, but criticizes Siux for not including the removal tool in the box—a minor but recurring annoyance for those who like to customize their setup.
A technical issue is also raised: the reviewer has experienced a “maracas effect” (loose particles inside the frame) with several Siux rackets, including the Fenix Pro 4. While this doesn’t affect play in the short term, it’s disappointing for a racket in this price range and raises questions about long-term durability.

Final thoughts: who should choose the Siux Fenix Pro 4?
The Siux Fenix Pro 4 is a racket built for advanced and aggressive players who want to maximize power and spin in their game. Its high balance, hard core, and textured face make it a formidable weapon for those who can handle its lively character and demand explosive performance. While it’s not the most forgiving option for defensive or control-oriented players, it shines in the hands of those who like to dictate play and finish points decisively.
