Expert Review: Cobra King F9 Speedback Irons


During my time testing the Cobra King F9 Speedback driver, fairway wood and hybrid, I also got an up close and personal look at the Cobra King F9 Speedback irons. This game improvement iron set is designed for players looking to improve their ball striking, while also gaining distance and forgiveness on off-center strikes.

The irons feature PWRShell E9 face technology and Speedback technology. Speedback technology in the irons raises the trailing edge in order to minimize the sole’s contact area for improved turf interaction. A deep undercut cavity helps the face to flex at impact, which results in faster ball speeds across the entire face. A co-molded medallion insert in the cavity dampens vibrations to improve sound and feel.

Comparing the F9 Speedback irons to its predecessor the Cobra King F8 irons, the size appears considerably larger. Even though the sole is raised up to minimize the amount of sole that interacts with the turf, it gives the iron a wider appearance, both looking down at address and simply taking a look at the iron in your hand.

With the added room, Cobra was able to add mass low and back through a steel belt that wraps around the back perimeter of the club head. This weight creates stability with a low CG, high MOI and incredible forgiveness.

To further increase stability, 33-grams of tungsten are located in the low toe and heel (within the hosel). This stable iron is able to create higher levels of inertia across the entire face. Higher inertia equals faster ball speeds.

Since these irons aren’t designed for players like me, I spent most of my time testing the Cobra King F9 Speedback irons on the range. What I found was that Cobra accomplished exactly what they were aiming to do with this set of irons. I saw extreme distances of the turf and even longer distances when I teed up the long irons.

In order to determine if Cobra accomplished their goal, I hit all sorts of shots. I took natural swings, intentionally toed the ball, took swings where I came down too steeply, and contacted the ground a little bit early. The results were as expected. Cobra successfully designed a high MOI, low CG iron for players looking for added ball speed, assistance in producing consistent distances and forgiveness for inconsistent ball striking.

If you are an improving player looking for any of these characteristics in your next iron set, give the F9 irons a try. They are also available in ONE Length and combo set with hybrids, as well.

With all that said, better players, listen up!

I found myself extremely surprised to see Rickie Fowler gaming the F9 Speedback 4-iron in his recent win at the Waste Management Phoenix Open. However, after thinking about this club’s characteristics it started to make more sense.

A player of Rickie’s caliber strikes the ball purely almost every swing, so to have a high MOI iron he can use as a driving iron can be an absolute weapon. He can use the higher lofted club (compared to something like a more traditional 2 or 3 driving iron) that produces a high ball flight with insane distances.

So, if you’re a better player, this strategy could be something you can utilize to keep your distances up while finding more fairways off the tee.
