What the differences mean
Every club the two sets share has exactly the same loft, starting with a 27.5° 7-iron. On paper there is no distance or trajectory difference: with the same swing, a 7-iron from either set should launch and carry about the same. The real differences are in how the heads are built, how they look at address and how they feel at impact, none of which a spec table can show. Lie angles and lengths match as well, so any fitting adjustment made to one set would carry straight over to the other.
Both are game improvement irons, built for roughly 10 to 25 handicaps. Perimeter-weighted cavity backs with wider soles, more offset and stronger lofts, aimed at mid handicaps. Because they target the same golfer, the decision comes down to the specific loft, feel and shaping differences rather than who the sets are made for.
The KING Speedzone is listed as cast hollow-body distance iron with a forged face insert and carbon fibre topline and the KING Radspeed as cast hollow-body distance iron with a forged face insert, carbon fibre topline and 3D-printed medallion. Both use hollow-body heads, so both trade a little feel for face flex and launch help.
The KING Radspeed arrived 1 year after the KING Speedzone, a typical one-generation refresh. Changes over that span are usually incremental: refined face thickness, revised weighting, updated looks and small loft tweaks rather than a new concept.
Which should you choose?
The KING Speedzone and KING Radspeed share the same lofts on every club on file, so the difference is in head construction, feel and forgiveness rather than trajectory.
