The cavity includes an ari flow restriction formed between the ball striking face and the rear face. The cavity is defined by various parameters including width and depth wherein the width of the cavity is substantially greater than the depth, the depth being at least 1/4 inch from the top surface of the club head and the width being at least 1/2 inch.
