1. An iron-type golf club head, comprising:
a heel portion, a toe portion, a top line portion, a sole portion, a leading edge, a trailing edge, a face oriented at a loft and having a face thickness, a face striking surface, a face center, a face rear surface, a rear wall extending from the top line portion to the sole portion and spaced apart from the face rear surface, and a hosel having a bore and a bore center that defines a shaft axis which intersects with a horizontal ground plane to define an origin point, and defines a shaft axis plane, wherein:
i) a portion of the face rear surface and the rear wall define a closed void within the club head so that majority of the face is not supported by the heel portion, toe portion, top line portion, and sole portion, wherein the closed void extends to the top line portion;
ii) a passageway is accessible from an exterior of the club head at a passageway opening and in communication with the closed void at a termination opening, and defining a passageway axis that intersects the shaft axis plane and intersects the face at an axis-to-face intersection point located at an elevation above the horizontal ground plane of less than the Ycg distance;
iii) the iron-type golf club head has a center of gravity located:
(a) vertically toward the top line portion from the origin point a distance Ycg;
(b) horizontally from the origin point toward the toe portion a distance Xcg;
(c) horizontally from the origin point a distance Zcg toward the trailing edge in a direction orthogonal to the vertical direction used to measure the Ycg distance and orthogonal to the horizontal direction used to measure the Xcg distance, wherein the Zcg distance is 0.299″-0.492″;
iv) in a horizontal section parallel to the horizontal ground plane and passing through the center of gravity, the closed void is located between the center of gravity and the face, with no portion of the closed void within the horizontal section extending behind the center of gravity, and a portion of the closed void is located at an elevation above the horizontal ground plane that is greater than the elevation of the face center; and
v) the passageway opening is located at an elevation above the horizontal ground plane that is less than the Ycg distance.
