12. A golf club comprising:
a shaft; and
a body portion coupled to the shaft and formed of a material having a first density, the body portion being comprised of a face portion including a measurement zone defined by a rectangle having the dimensions of 0.5 inch by 1.0 inch with a geometric center that coincides with a geometric center of the face portion and having a lowest COR that is at least 93 percent of a maximum COR;
a crown portion formed of a second material having a second density that is less than the first density, such that the club head has a center of gravity located below a horizontal plane containing the geometric center of the face portion; and
a dampening layer juxtaposed the body portion and the crown portion for acoustical attenuation between the frequencies of 3800 Hz and 10,000 Hz.
