SIUX vs NOX: which padel racket should you choose?

SIUX Beat Control 3 2026 is round and low-balanced, with a fibreglass face and Soft EVA core. Its listed weight range is 355–375 g. NOX X-Hero 2026 is also round, pairing a fibreglass face with a carbon frame and HR3 White EVA, at 350–360 g.

X-Hero's upper listed weight is 15 g below Beat Control's upper limit. That makes NOX the more direct starting point if you are trying to avoid a heavier unit. The ranges still overlap between 355 and 360 g, so this is not a claim that every Beat weighs more than every X-Hero.

Choose Beat when a known low balance is important and its weight range works for you. We do not have a verified balance figure for X-Hero. You cannot settle the handling comparison from scale weight alone, especially after fitting your usual overgrips.

Both face descriptions can be confusing. SIUX uses Fiberglass 3K and NOX uses Fiber Glass 3K. These are fibreglass hitting surfaces. X-Hero's carbon frame does not turn its face into carbon, and a material label is not a performance score.

For a first purchase, borrow a familiar club racket and identify one thing you want to change. If you are repeatedly late getting into position, try the lower-weight candidate. If you already like a round, low-balance setup, compare Beat's handling before spending more on a professional signature model.

Trilogy Pro 5 is the 2025 SIUX model with a round head, low balance, a 40K carbon face and EVA Soft. Its weight range is 355–375 g. Equation Soft Advanced 2026 is round and medium-balanced, with a fibreglass face and HR3 Soft EVA, at 360–375 g.

Start with Trilogy if low balance is a deliberate preference and you want to investigate that carbon construction. Start with Equation Soft if you want the explicitly soft NOX core and a medium-balance round racket. These are two options for the same broad buying need, not identical products at different prices.

Neither should automatically be called lightweight. Both reach 375 g, and the small difference at the lower end does not tell you which unit a retailer will supply. If you need a specific weight, ask before ordering.

The Pro label on Trilogy also does not establish a harder feel than Equation Soft. Trilogy uses a soft core, while other SIUX Pro models serve different preferences. Comparing the actual construction is more useful than treating Pro and Advanced as equivalent grades across brands.

In his 2025 SIUX range article, Stéphane Penso described Trilogy as one of the round, softer options outside his top three. That supports its place on a softer shortlist, but the article is not a controlled comparison with Equation Soft. The specific difference we can establish here is low versus medium balance and carbon versus fibreglass construction.

If you get a trial, start with placement. Compare lobs, blocked volleys and short defensive swings, watching whether the ball reaches the depth you intended. A firmer or softer sensation is only useful if you like the resulting response.

The Diablo selected here is SIUX Diablo Pro 2026 Night Blue. It has a teardrop head, medium balance, a 24K TeXtreme carbon face and an EVA core, with a 355–375 g specification. Our researched catalogue classifies its feel as firm.

The NOX is the standard AT10 Genius 18K Alum 2026, with a teardrop head, medium balance, an 18K aluminised carbon face and a multilayer MLD Black EVA core. Its listed range is 360–375 g, and our researched feel classification is medium.

Diablo is the first model to investigate if you actively want a firmer response. AT10 is the alternative when you want to compare the standard medium-balance teardrop without making the Attack version your default. These feel labels are editorial classifications, not measurements from a shared test rig.

The 24K and 18K numbers cannot decide the winner. The faces, resin systems, layups and cores form different complete constructions. A larger K label does not establish more power, better control or longer life.

If you are replacing an older Diablo, try this exact 2026 version before buying it on familiarity alone. The same applies to an older AT10: a retained family name is not a promise that the response stayed unchanged. Check the model generation as carefully as the brand.

For both, use your normal grips when comparing. Start with the factory setup before adding optional accessories, and allow for those additions when considering total weight. Judge the racket across a full session, including rushed returns and ordinary rallies.

SIUX's Beat, Trilogy, Diablo, Electra and Fenix names point to different model families. Pro, Elite and other suffixes then need another check. The round Trilogy Pro in this comparison is enough to show why Pro should not be read as shorthand for a hard, high-balance attacking racket.

NOX requires the same care. Equation Soft and Equation Hard are different choices. The standard AT10 Genius 18K Alum and AT10 Genius Attack 18K Alum are different versions, including a change from teardrop to diamond in the 2026 range.

Our three pairs cover a first purchase, a softer round option and an experienced player's teardrop comparison. They do not rank every racket either company makes. If you already know you want a high-balance diamond, use the full brand guides to make a separate shortlist instead of forcing one of these six to fit.

A broad range can hide a meaningful difference between two examples of the same model. Beat, Trilogy and Diablo each cover 20 g in their specifications. Treat a reviewer's experience with one unit as evidence about that setup, not a precise description of every unit on sale.

If weight is a deciding factor, ask the shop whether it can confirm the individual racket's weight. Add your usual grip and protection allowance. A low-balance 375 g racket and a lighter medium-balance racket are different options; neither balance label removes the need to consider total mass.

Compare the offer for the exact racket you would actually use. A reduced Trilogy Pro 5 price may make the 2025 model worth investigating, but age or discount alone does not establish value. Check condition and return terms alongside the specification.

The prices beside our selected products come from connected retailer offers. They can change without changing the editorial recommendation. Our partner coverage is a selection of the market, so use it as a buying route rather than proof of the lowest price everywhere.

We do not have controlled failure-rate data that makes either brand a durability winner. Individual damage reports can be useful questions to raise, but they do not account for use, impacts or the number of rackets sold. A brand-wide reliability verdict would require better evidence.
