As a result, Titleist designed these irons to focus on not only the traditional feel and performance but also to optimize launch conditions and ball flight based on the targeted players ball speed range. To achieve the ball speed and launch conditions, the AP1 and AP2 incorporate multi-material construction and a dual cavity. The back sole is comprised of a tungsten nickel alloy intended to optimize launch conditions and for a larger range of swing speeds.
