An iron type golf club head includes a body 12 having a front face 22 arranged for impact with a golf ball, a back face 23, a heel portion and toe portion. A hosel 14 is connected to the heel portion of the body. A perimeter weighting element (24, Fig 1, not shown) protrudes rearwardly from the front face and defines a primary cavity 26 in the back face 23 of the body 12. The perimeter weighting element includes a top rail 28 and a sole 30, which extend between the body heel and toe portions along an upper portion and a lower portion, respectively, of the body. An interior wall 46 extends from a first end connected to the perimeter weighting element adjacent the body heel portion through the primary cavity between the top rail and the sole to a second end connected to the perimeter weighting element adjacent the body toe portion to define an elongated secondary cavity or tuning port 48 within the primary cavity 26. The interior wall 46 is integrally formed on a bottom surface 44 of the primary cavity 26 and extends from the bottom surface of the primary cavity in a direction D that is substantially perpendicular to the longitudinal axis A of the hosel. This orientation of the interior wall provides the secondary cavity, i.e. the tuning port, with a low profile while also moving the center of gravity of the club head lower and farther away from the front face. |
