1 and 2 show sound measurements taken at three points on a traditional golf club head and the preferred embodiment of the golf club head 10 as shown in tables 1 and 2 the center of gravity height adjustment assembly 100 included in the preferred embodiment minimizes amplitude db of the sole 40 compared to the traditional golf club head construction while keeping the face 50 amplitude within a desired range of approximately 3000 to 4000 hz and while remaining at the highest amplitude in the system the presence of the tube 110 thus improves the overall sound quality and durability of the golf club head 10 which allows for the use of cheaper metals and cheaper manufacturing processes the tube 110 also creates a peak that is more than 8 db higher than all other peak frequencies of the preferred embodiment and which is greater than 3000 hz as shown in fig1 as shown in fig1 this type of peak is not present in equivalent golf club heads having adjustable weighting but lacking the tube 110 of the present invention the preferred sound of a driver type golf club is in the 3000 6000 hz range and it is preferable to have only one peak with an amplitude of 8 20 db greater than.
