The unique forging process and patented heat-treatment process of the T9S+ face powers a thinner, hotter impact area that is precision machined to elevate ball speed across the entire face for 16% more flexing and when paired with the aerodynamic gains, results in ball speeds nearly 2 mph faster. By making the face 6% thinner and 9% lighter than its predecessor, extra weight was placed strategically to tighten dispersion even further. The forged face was also instrumental in producing the powerful feel of the driver.
With a combined MOI over 9,000 and the deepest CG location in golf, there's no more forgiving driver available. A higher-density back weight helps with forgiveness and allows you to customize your swing weight. You can fine-tune your launch conditions prior to a round by adjusting loft up to +-1º.
Extensive research and computer simulation coupled with music theory allowed the engineers to design internal architecture that fine-tuned the frequencies to produce a deeper, more muted sound. One tour professional compared it to ?the satisfaction of puring a persimmon driver with the modern technology of the G400.?
