the first golf club further comprising a first loft angle (LA 1 ) of between 15 and 25 degrees, a first face stabilizing bar extending from the heel to the toe, a plurality of first apertures formed in the first face stabilizing bar, a first back panel coupled to the first face stabilizing bar, and a first center of gravity positioned horizontally from the face center toward the hosel by a first distance of between 0 mm and 2.5 mm,
the second golf club comprising a second loft angle (LA 2 ) of between 26 and 36 degrees, a second face stabilizing bar extending from the heel to the toe, a plurality of second apertures formed in the second face stabilizing bar, a second back panel coupled to the second face stabilizing bar, and a second center of gravity positioned horizontally from the face center toward the hosel by a second distance of between 0 mm and 2.5 mm,
the third golf club comprising a third loft angle (LA 3 ) of between 37 and 47 degrees and a third center of gravity positioned horizontally from the face center toward the hosel by a third distance of between 3 mm and 4 mm; and
wherein a plurality of first ribs extend from a face portion of the first face stabilizing bar to a back portion of the first face stabilizing bar.
6. The set of golf clubs of claim 5 , wherein a plurality of second ribs extend from a face portion of the second face stabilizing bar to a back portion of the second face stabilizing bar.
7. The set of irons of claim 5 , wherein a first combined length of the first apertures is greater than a second combined length of the second apertures.
8. The set of irons of claim 5 , wherein the first golf club comprises a weight pocket adjacent the toe and a first weight member having a mass of between 10 g and 40 g secured therein and the second golf club further comprise a weight pocket adjacent the toe and a second weight member having a mass of between 20 g and 50 g secured therein.
9. The set of irons of claim 8 , wherein the first golf club and the second golf club further comprise a weight member adjacent the heel.
10. A set of golf clubs comprising a plurality of first golf clubs, a plurality of second golf clubs, and a plurality of third clubs, wherein:
each of the first, second and third golf clubs comprise a heel, a toe, a topline, a hosel, a sole and a front face having a face center, and
each of the first golf clubs further comprising a first loft angle (LA 1 ) of between 15 and 25 degrees, a first face stabilizing bar extending from the heel to the toe, a first aperture formed in the first face stabilizing bar, a first back panel coupled to the first face stabilizing bar forming at least a portion of a first back wall, and a first center of gravity positioned horizontally from the face center toward the hosel by a first distance between 0 mm and 2.5 mm,
each of the second golf clubs comprising a second loft angle (LA 2 ) of between 26 and 36 degrees and a second center of gravity positioned horizontally from the face center toward the hosel by a distance between 0 mm and 2.5 mm, and
each of the third golf clubs comprising a third loft angle (LA 3 ) of between 37 and 47 degrees and a third center of gravity positioned horizontally from the face center toward the hosel by a distance between 3 mm and 4 mm, and
