Tri-Force Face TechnologyAt the centre of the Quantum Max D is Callaway’s Tri-Force Face, a fully integrated construction that layers ultra-thin, high-strength titanium with Poly Mesh and carbon fibre. Each material is chosen for its role in managing energy transfer, working together to generate fast ball speeds while maintaining stability on off-centre strikes. The result is powerful speed that feels controlled rather than volatile.Next Generation Ai-Optimised FaceAdvanced Ai face mapping precisely tunes flex across the entire hitting area, accounting for how the three face materials interact under impact. This next-generation optimisation helps maintain consistent speed, launch, spin, and accuracy across a wider range of strike locations. Ball speed holds up when contact drifts from centre, supporting tighter dispersion and more predictable carry.Internal Heel Weighting and Draw BiasWeight has been positioned in the heel section of the head to promote a slight draw bias. This helps reduce slice tendencies and supports a straighter, more playable ball flight. The draw bias is subtle rather than exaggerated, assisting without forcing a specific shot shape.Confidence-Inspiring ShapeThe 460cc head combines high MOI with a refined, player-friendly profile. At the address, the shape feels stable and reassuring, encouraging committed swings without appearing stretched or unwieldy. The overall design prioritises forgiveness and launch while maintaining a clean look behind the ball.OptiFit Hosel AdjustabilityCallaway’s OptiFit hosel provides independent loft and lie adjustability, offering eight total configurations. This allows launch angle and shot shape to be fine-tuned during fitting, whether the goal is a higher trajectory, a straighter flight, or additional draw bias. The adjustability supports fitting precision rather than constant experimentation.On-Course PerformanceOn the course, the Quantum Max D produces a high launch with controlled spin and a stable, slightly draw-biased flight. Centre strikes feel solid and fast, while off-centre hits retain direction and carry more effectively than expected. The head remains composed through impact, helping maintain confidence when swing tempo or strike quality varies.Who It SuitsThe Quantum Max D is best suited to golfers seeking easy launch, maximum forgiveness, and help in reducing a slice. it’s an ideal option for players who want dependable distance and tighter dispersion without moving into an oversized or overly corrective design.Specifications Loft Lie Volume 9.0 ° 59 ° 460cc 10.5 ° 59 ° 460cc 12.0 ° 59 ° 460cc Built In-House at Nine by NineEvery Callaway Quantum Max D Driver is assembled in-house at the Nine by Nine Golf workshop.
