an elongated stiffening member permanently secured within the hollow interior region of the golf club head and having a first end coupled to the crown, a second end coupled to the sole, and an elongated intermediate portion spanning across the hollow interior region from the first end to the second end;
wherein the intermediate portion is suspended within the hollow interior region such that the intermediate portion does not contact any portion of the crown or the sole;
wherein the stiffening member is co-formed with the club head body;
wherein the first mode frequency of the golf club head, generated upon impact with a golf ball, is greater than 2,800 Hz; and
wherein the stiffening member increases the stiffness of the golf club head and increases the frequency of sound vibrations produced by the golf club head when striking a golf ball.
