Diamond Face 2.0/ Cup Face Technology - The TE-400 metals feature Diamond Face 2.0 technology with 42 different thick and thin diamond shapes behind the face of the metals for an enhanced sweet spot. Diamond shapes of varying thickness create “mini-trampolines” behind the face, combining with a Cup Face construction to produce greater face flex, faster ball speeds and better performance on off-center hits.
High MOI Rear Sole Weight in a Deep CG Casing - A back weight is strategically placed to the extreme rear of the TE-400 driver, fairway, and hybrid. The extreme rear weight is housed in an all-new Deep CG Casing that places more mass at the extreme trailing edge of the clubhead. The back weight and Deep CG Casing creates an extremely high M.O.I. rating for top in-line stability.
Acoustic Resonance Channels - Upgraded acoustic engineering is achieved through Acoustic Resonance Channels (A.R.C.) Engineering. The A.R.C. sound channel system is a visible technology that can be seen on the sole of the clubhead. Internally, these channels bounce sound on the inside of the club head to provide top-shelf sound and feel.
Power Channel - The Power Channel on the sole of the club behind the club face is deeper for better weight distribution and increased face flexing. The Power Channel delivers amplified ball speed and less spin, as well as added forgiveness on shots struck lower on the face.
VIBRCOR Technology - VIBRCOR tech comes to the Hot Launch line for the first time with the TE-400 Iron. VIBRCOR is a high-grade TPU strategically placed in the deep undercut pocket to create a new speed-inducing and feel-enhancing internal technology. VIBRCOR creates a distinct feel of the clubhead at impact that dampens sound and shock, while also creating perimeter weighting around the entire clubhead for maximum forgiveness and power and ball speed enhancement off the face.
360-degree Undercut Cavity - The deep 360° Undercut Cavity promotes a myriad of game-enhancement benefits in a classic iron design. The expanded undercut cavity provides maximum forgiveness and consistent performance. It also delivers an increased repulsion effect for high-speed power off the face and a higher launch angle and enhanced forgiveness.
Wide Sole Design - A wider sole design on the TE-400 Iron lowers the Center of Gravity and offers superior bounce and increases launch for cleaner, high-flying shots. The wide sole design leads to cleaner turf interaction for more consistent shot making.
Advanced Toe Weighting - Advanced toe weighting technology in the TE-400 Iron maximizes stability on impact and provides better off-center hit distance from the face of the iron. The strategically placed toe weight elongates the sweet spot and provides a pure feel off the face of the irons.
Power Lofted - The lower and deeper Center of Gravity allowed the TE-400 irons to be power-lofted for added distance and lower spin with the same launch characteristics as a standard lofted iron, making for a modern long-distance iron design that will provide extra distance with the same apex height expected from each iron.
