The series includes three clubs: the Quantum Mini Driver, Quantum Mini Bertha and Quantum Mini Spinner. The company said the clubs are designed to close common distance gaps between a driver, fairway wood, hybrid and long iron, allowing more precise yardage control depending on course conditions.
The Quantum Mini Driver is intended to blend driver distance with the stability of a fairway wood. A compact head and shorter shaft are meant to reduce pressure on tee shots. It uses the Step Sole structure found in fairway woods to reduce turf friction, enabling use on second shots from the fairway. The club also features a Tri-Force Face and a next-generation AI-optimized face design aimed at delivering consistent ball speed.
The Quantum Mini Bertha is positioned as a 4-wood concept to bridge the gap between a 3-wood and 5-wood. A larger head and shorter shaft are designed to improve center-face contact. Its Speed Wave 2.0 structure places about 40 grams of weight low on the front of the head to maximize energy transfer efficiency. It also includes an OptiFit 4 hosel to adjust loft and lie angle.
The Quantum Mini Spinner is designed for attacking greens with a higher launch and more spin. Callaway said a draw-biased AI face design, deep-face structure and higher center-of-gravity design increase spin. The club is about 0.5 inch shorter than a standard fairway wood to improve impact accuracy and control.
A Callaway Golf Korea official said the Quantum Mini Series was developed to address the distance gaps and club-selection challenges golfers most often face during rounds. The official said the clubs, optimized for specific situations, are intended to help golfers deliver more consistent performance and play with greater confidence.
