Who’s It For
Golfers who want maximum forgiveness and confidence at address, with an oversized shape that delivers high launch, powerful speed, and consistent carry.
Modern 360° Undercut
The Modern 360° Undercut Cavity is designed to deliver faster ball speeds, higher launch, and more forgiveness across the face, thanks to its advanced two-piece design with extreme perimeter weighting and a fully exposed undercut for added flex where golfers need it most.
Progressive Tri-Sole Design
The Progressive Tri-Sole Design promotes cleaner, more consistent contact across the set, with a reengineered sole geometry that adapts from long irons to wedges for smooth turf interaction and efficient speed retention—even on heavy strikes
Next Generation Ai-Optimized Face Design
The Next Generation AI-Optimized Face delivers faster ball speeds and more consistent launch, spin, and dispersion by intelligently shaping the face to match real-world impact patterns and expand the sweet spot.
Urethane Microspheres
Urethane Microspheres enhance sound and feel at impact by absorbing unwanted vibration, delivering a softer, forged-like sensation in a high-speed game-improvement head.
Oversized, Confidence-Inspiring Shape
Quantum Max OS is built for higher launch and maximum forgiveness—all in an oversized shape that inspires confidence at address.
