The KING F9 SPEEDBACK™ Fairway is the first of its kind to feature a CNC Precision Milled Face, which, according to test results, delivers up to 2.5mph in increased ball speed, compared to traditional hand polished fairway faces.
SPEEDBACK™ Technology in the fairway utilizes a low, back tungsten weight and re-engineered Baffler® rails that move the CG low and deep, and improve turf interaction, to deliver more club and ball speed at impact. A fixed, 15g tungsten weight positioned low and back, promotes high, towering ball flights and maximum forgiveness. Progressive Baffler® Rail Heights are designed shallower in the lower lofted fairways and steeper in the higher lofted fairways to account for varying attack angles. 360 Aero™ polymer crown and titanium sole trips positioned relative to the direction of airflow around the clubhead, further help to reduce drag and increase club speed. An ultralight carbon fiber crown saves discretionary weight up high, to move the CG lower and deeper for higher launch with increased forgiveness. PWR Ridge™ crown designs add rigidity to the lightweight carbon crown structure to promote more energy return to the ball to maximize ball speed
