Siux Fenix Pro 4

Introduction

The Siux Fenix Pro 4 is a high-power diamond racket for advanced players who want to end points fast.

Shape & Balance

The diamond shape moves the balance point toward the head, so you feel the weight at the top of the racket. That gives you the momentum for powerful shots but makes the racket less head-light.

You need a committed swing to manage it. if you're late or off-balance, you'll notice the sluggishness.

Grip

The grip feels secure and non-slip during long matches. The tacky surface helps you keep a firm hold without squeezing too hard.

At 355-375g, your arm may feel fatigue toward the end of a three-setter. A good overgrip can help, but the weight is a factor.

Power & Control

The high power score of 9.6 shows in real play: every smash and aggressive stroke has real pace. You can generate winners from defensive spots, which is rare.

The control score of 9.2 is a standout for a diamond racket. You won't lose accuracy, as long as your footwork is sharp. You'll place the ball well and keep it low.

Comfort & Speed

The EVA hard core gives a firm, solid feel on contact, which can be harsh on off-center hits. But the large sweet spot (8.2) cushions the good ones.

At 7.4 maneuverability, it's not quick in the air. You'll want good wrist strength for volleys, but the stability the weight provides helps block hard smashes.

Materials & Durability

The frame is carbon fiber, which is strong and moderately light. The faces use 18K carbon, a high-end material that provides a stiff response.

The materials feel durable for regular play, but the hard core should show some signs of wear over time—just like any racket.

Analysis

The Fenix Pro 4 is built for attack. With a power rating of 9.6 out of 10, you get explosive smashes and fast, aggressive play. The control score of 9.2 is surprisingly high for a diamond, so your shots stay accurate even when you're swinging hard.

The rebound of 7.4 means the ball comes off the face quickly, helping you hit with depth. But it also means softer, touch shots—like drop shots or delicate volleys—need a precise hand to avoid popping up.

Maneuverability at 7.4 is solid but not elite. This is a heavy racket (355-375g), and the diamond shape puts weight in the head, so you feel the swing weight. It's not sluggish, but it rewards a prepared swing over a quick reaction.

The sweet spot is high at 8.2, which is good for a diamond frame, so mishits still go somewhere useful. That helps, because the hard EVA core gives you less forgiveness on off-center hits.

If you're a beginner or an intermediate who values defense and quick exchanges, look elsewhere. This racket demands solid technique and isn't easy to control on the fly.
