Q
Is this a full set of irons or just 3 clubs as stated in club description box?
asked by Eddie G. on 7/7/2021
A
The way the listings work, all irons in between the two separated by a dash are included. In other words, 6-PW,AW would include the 6,7,8,9,PW, and AW.

asked by Heather N. on 9/7/2021
A
Unfortunately, due to the size of our inventory, we are unable to verify if a used set has the Connect grips on it.

Cobra King F9 Speedbacks I love them 		By Paul C. on 5/26/2020
43 out of 48 people found this review helpful.
Handicap: 11-15  Plays Golf: I play weekly  Dexterity: Right Hand

Prior to this purchase (4-GW), I would never have believed that the clubs made that big a difference in my game. However, my results speak for themselves. I also use the Cobra King F9 driver. The clubs have a very nice feel and sound. I turn 69 in July. And no, I am not your usual senior citizen (personal trainer).

With my old clubs I hit my GW about 105 yds. With my F9s, about 130 - 135.

I hit my PW about 120 yds, but with the F9, about 140 - 145.

The increases follow for all my clubs. I am thoroughly impressed.

The guys I play with are very interested in the King Cobra F9s.

Handicap: 6-10  Plays Golf: I play more than once a week  Dexterity: Right Hand

These Cobra King F9 irons were my second purchase of Certified Clubs offered from Global Golf. These irons were in perfect (like new) condition. These irons feel great and are long and very accurate. Buy Certified and save $$$$.

Underrated Irons 		By Miguel D on 6/12/2020
8 out of 9 people found this review helpful.
Handicap: 6-10  Plays Golf: I play weekly  Dexterity: Right Hand

These F9's are amazing irons. The tech just works! I though my Ap1 714 were the best irons I have ever used in my life. While they are amazing, the F9 just blows them out of the water. Feel is amazing, you can feel the ball pop off the face, distance is plenty with these, consistency, looks and forgiveness is high on bad shots, all boxes ticked. I don't like the chrome though but other than that, these are amazing irons!

The King Has Returned 		By Josh M. on 3/12/2021
2 out of 2 people found this review helpful.

Quick delivery and clubs were in like new shape. Loving the irons, jumping off the face and very forgiving. Only criticism is that the F9s by default have the Arccos sensors embedded. I thought my clubs would have those, but the grips were switched out. Would be nice for 3balls to provide details if OEM grips or have been replaced

I was looking everywhere for these irons. No luck until 3 balls popped up. The description of these were rated as "AWESOME " used. I couldnt be happier when I opened the box to find what I would consider brand spanking new. Thx 3 balls

Cobra King F9 Speedback Irons Overview

Back of iron head

Speedback Design

The speedback design adds mass to the lower and wider parts of the club, lowering CG and allowing players to maximize ball speed while still having a conventional size sole width.

inside and back of iron head removed

Multi-Materail Medallion

The three materials in the speedback iron medallions are aluminum, thermoplastic polyurethane (TPU), and acrylic foam. All three materials are lightweight and act as dampeners to the vibrations the club gives off at the striking point, making these clubs have a responsive feel to them that players want.

Progressive groove shaping

Spin Technology

In the longer irons (4-7), v-shaped grooves were milled into the face to create less spin for more distance and flight time. In the shorter irons (8-PW), u-shaped grooves were milled into the face for optimized spin for improved control and accuracy. In the wedges (GW-SW), tightly spaced u-shape grooves were milled for extra spin and precision around the green.

Progressive hosel length and shape

Hosel Length

The CG is lowered in the long irons (4-6) for extra launch and distance with those clubs. In the 7-9 irons, a slightly longer hosel promotes a bit less launch and lowers the CG some. The wedges have the longest hosel's, raising the CG up the most giving those clubs more accuracy than the other irons.

The Cobra KING F9 Speedback irons have several new innovative features that make these irons built for speed and performance. Keep reading to find out more.


Speedback™ Technology and High MOI Design



Cobra uses its new Speedback™ technology in the KING F9 Speedback irons. This technology adds mass to the sole of the club, pushing the CG low for easy launch and added forgiveness. The mass doesn’t give the irons a bulky look and actually helps with turf interaction.

To further boost MOI, Cobra designers placed a total of 33 grams of tungsten in the heel and toe of the KING F9 irons. The weight stabilizes the head at impact on mishits so those shots aren’t penalized as much.


Co-Molded Medallion



On the 4-7 irons, Cobra uses a Co-molded medallion to dampen vibrations and give the clubs a soft feel. The 3-piece medallion is made with aluminum, TPU and acrylic foam.


Forged E9 PWRSHELL™ Face Technology



The face of the KING F9 Speedback irons has forged E9™ technology, which varies the thickness across the face, increasing ball speed on off-center hits and expanding the sweet spot.

The face also utilizes the company’s PWRSHELL™ tehcnology, where the face wraps around to the sole of the club, creating a channel that flexes in and out at impact. This reaction creates higher ball speed and launch angles.


Progressive Spin Tech and Hosel Length



Cobra uses progressive groove patterns, which are CNC milled for consistent performance, called Progressive Spin Tech. The grooves on the 4-7 irons have a V-shape that reduce spin and increase carry distance. On the 8-PW, the grooves have a U-shape that increase control and accuracy. The GW and SW have shallow grooves that are close together to maximize spin around the green.

The hosels also get progressively longer as the clubs shorten. This design ideally controls the CG location and produce the best launch conditions for each club in the set.


Cobra Connect



Each club in the Cobra KING F9 family has Cobra Connect powered by Arccos sensors in the grip. The sensor tracks distance, accuracy, and more automatically. The data collected gets sent to the Arccos Caddie app, showing you areas that you’re doing well and what you can work on to improve your game.
