Abstract
A putter-type golf club head with a sound chamber is disclosed herein. The club head comprises a body and a two-piece face insert disposed over the sound chamber. The sound chamber comprises a central sound sub-chamber and an outer sound sub-chamber, while the face insert comprises a first, metallic piece that includes a central recess, which is filled with a second, polymeric piece. The metallic piece is welded to the body, and the polymeric piece is adhered to the metallic piece. The body also includes at least one through-bore extending from the sound chamber through a back wall of the body. The body, the sound chamber, the face insert, and the through-bore amplify the sound generated by the putter-type golf club head striking a golf ball.
