The Srixon W-506 Driver is the world’s first high volume driver to feature Srixon’s proprietary Impact Power Body construction, a remarkable advancement in driver design, where not only the clubface but the sole and backwall of the driver all have varying wall thicknesses. The W-506’s Impact Power Body construction – the face, sole and backwall – all work together, which allows the entire clubhead to deform at impact. This optimum deformation allows the ball to stay on the clubhead fractionally longer, helping prolong the spin reducing momentum, so the golf ball launches high with low spin and goes further. This phenomenon, known as “Recoil Theory” was systematized by the technical staff at Srixon and applied into the technology of the W-506. The thin forged titanium clubface varies in thickness in three places to help provide maximum allowable energy transfer. Because of the larger 450cc clubhead size, the W-506 driver also has a larger COR zone – elliptical in shape – which extends from high toe to low heel matching the common strike patterns of all golfers. The high power weight of the W-506 moves the centre of gravity (CG) low and deep in the clubhead to help further promote those optimum launch conditions. In addition, the W-506 features Srixon’s unique Autoturn Design in which the CG is moved progressively towards the heel as the lofts increase, making the higher lofts easier to square at impact for the slower swingers who generally favour them. Complementing the W-506 is the proprietary Srixon SV 3004 graphite shaft which has been custom designed specifically for the W-506. The flex, torque and weight characteristics of the SV 3004 have been optimized for the dynamics of the W-506 design.
