Nox AT10 Genius Attack 12K Alum XTREM 2026 by Agustín Tapia

No reviewer has published a verdict on this racket yet. So this page reads what the specs say, and says plainly where they are silent.

Diamond or teardrop: the two changes that turn Control from Medium to Low

Put it next to the teardrop Nox AT10 Genius 12K Alum XTREM. The face is the same Carbon 12K Alum Xtrem. The core is the same HR3 Black EVA. Thickness is 38 mm on both, and the weight range is 360 to 375 g on both.

Two things differ. The head is a diamond here, and the balance is High instead of Medium. Those two changes take control from Medium to Low. Not a different material, but a different geometry.

On court, a diamond keeps the mass toward the top of the head. A high balance adds to that. You get more punch on overheads and smashes. You also get a racket that is slower to turn and less forgiving when the ball lands off-centre.

Tapia's name on a Professional racket: what the label asks of you

Nox lists the level as Professional and names Agustín Tapia as the pro player. Treat that as a hint about the demands, not a promise of results. A racket this heavy and head-heavy rewards solid technique and a fit arm.

If you are an intermediate player moving up, ask yourself two things. Is your swing already compact? Is your contact point consistent? If not, the teardrop sibling is the gentler way into the same line.

HR3 Black EVA and a stiff carbon face: where the High power reading comes from

The meters rate power as High, and the drivers are easy to list. The HR3 Black EVA core is read as hard. The Carbon 12K Alum Xtrem face is read as stiff. The diamond shape, the weight and the high balance all push the same way.

The product page says the racket was developed with Tapia for aggressive players who want maximum power and a solid, firm feel. That is marketing, but it fits what the meters show: High power, Low everything else. The page also claims the core has the highest memory effect and that the carbon gives a finer, more uniform surface. Those are the brand's claims, not measurements.

Nox lists the surface as Dual Spin. What that texture involves is not spelled out in the specs, so treat any spin claims with care.

The same hard core and stiff face also lower comfort and sweet spot. Power has a downside. If your elbow or shoulder already complains, a racket with this profile is a risk. You can limit that risk. Pick the lower end of the weight range where you have the choice. Also try a few sessions of light hitting before you play matches with it.

A 30 mm grip extension and a counterweight kit

The handle is listed as an Oversize Grip with a 30 mm grip extension. The product page says that suits large hands or players who like a longer grip.

Nox lists a Weight Balance counterweight system for personalising the balance. The product page says it works with small interchangeable pieces. That gives you some room to shift the balance of a racket that is already head-heavy. It is the one lever you control after buying.

Attack 2026 or Attack 2027: a core swap and a new weight system

The successor, the Nox Genius Attack 12K Alum XTREM, keeps the face, frame, shape, balance label, level and weight range. Three things change. The core becomes MLD Black EVA. The handle is listed as a plain Oversize Grip. The weight system is described as allowing up to 8 g. Whether the new core plays differently is not something the specs can tell you.

If you want a diamond with a different face, look at the Nox AT10 Genius Attack 18K Alum 2026. It has Carbon 18K Alum and an MLD Black EVA core, and the same meters.

Nox does not publish the balance in millimetres or the head area. You have the label High and nothing finer. That makes it hard to compare against, for instance, the Siux Fenix Pro 4, which is also labelled High with 38 mm thickness. Treat the label as a direction, not a number.
