Golf club heads have an Impact Response Modulator disposed in the sole to improve ball flight characteristics. The Impact Response Modulator includes a casing with a plurality of casing walls that form an aperture therebetween. The club head further comprises a faceplate with a sole return that integrally forms the entire casing. The faceplate structurally reinforces the IRM by forming the casing walls out of high-strength material, thereby improving faceplate deflection while maintaining sufficient durability.
