King F9 Speedback


The KING F9 SPEEDBACK™ Driver is the first of its kind to achieve true optimization of aerodynamics and low CG, making it the fastest and longest COBRA driver.


For the first time, revolutionary Speedback™ Technology combines the benefits of a highly aerodynamic clubhead shape with a low, deep CG, to deliver the Ultimate Formula for Speed.


CNC Precision Milled Face

The industry’s only CNC milled driver face delivers our thinnest, hottest face repeatedly on every driver we manufacture.


360 Aero™

Polymer crown trips and titanium sole trips are positioned relative to the direction of airflow around the clubhead to reduce drag for faster clubhead speeds.


Ultralight Carbon Fiber Crown

King F9 Driver Tech

Golf's first-ever carbon wrap crown design delivers a larger carbon fiber area and saves 4 grams compared to a traditional carbon fiber crown.


E9 Speed Tuned™ Technology

E9™ and Dual Roll™ technologies are optimized for each driver loft, while CNC milling creates precise bulge and roll curvatures to improve driving accuracy and distance on off-center hits.


Front/Back Adjustable CG

An adjustable weight system allows you to move the CG forward or backward to help you fine-tune launch and spin characteristics to improve your distance.


MYFLY8® With Smart Pad™

8 easily adjustable loft settings help you manage trajectory and fine tune launch conditions to maximize distance while Smart Pad keeps the face square regardless of the loft setting.


Premium Aftermarket Shafts

The F9
September 10, 2019
I ordered this club for the grand prize at my golf tournament. The club is beautiful, made it to me in 3 days. I know it will be a 5 star club from other reviews I have read but the only problem is that they did not send the tool to adjust the club. For this expensive of a club I assume this must be a mistake? Not sure if this a rock bottom or a Cobra issue? Otherwise
ConsNo adjustment tool with the driver

Coming off just last year's F8+(which I loved), I don't recall ever seeing such a performance jump in one season. They got every single performance characteristic right...distance is up, straighter and more forgiving, clubhead speed is up (2mph), better sound and feel. Best driver Cobra has ever produced, hands down.

Reduced spin!
July 31, 2019
I recently upgraded from a Callaway diablo edge. I got it with the �€˜stiffer-end�€™ shaft, which touted to reduce spin e.g. exaggerated fades/slice. . .and I�€™m really seeing a difference; improved accuracy/distance. And that sound it makes when you hit the sweet spot. . .absolutely incredible. 0 regrets on this purchase!
ProsBetter accuracy, less side spin
ConsThe adjustable weights don?t really seem to make a difference; maybe it?s just me

Club is 5 star
July 25, 2019
This is a great upgrade from my previous f6 plus model. Forgiving with great launch in good shots. Would recommend the product. I rate 3 stars because rock bottom incorrectly advertised this as a free in home in 2 product meaning I should have it in 2 days. Part of the appral of this was the ability to take in a golf trip a week after order. It took over 2 weeks and multiple follow ups on my part before club was shipped direct from Cobra.
ProsGreat golf club which has added about 20 yards to my drive
ConsFalse advertisement around how soon club would be received.

Hot Face

I received my Cobra King F9 Speedback driver a couple of weeks ago and put it into play that afternoon. After hitting it on the range prior to the round, I lowered the loft by 1.5 degrees and ripped it on the course hitting 9 of 14 fairways with about 15 - 20 yards more distance than my 5 year old Ping G30. I am a fan! The ball comes off the club with low spin and very high.. it is fun to watch and good to be hitting it on the short grass!
ProsSpin rate and launch angle are much better with this driver. Set up to the ball is easy the distance is longer.
ConsTough to find any so far...

I have only played one round with this club. Seems to be raining a lot here this time of year. Club feels good and looks good, we will see how it turns out always have good things to say about cobra drivers
