This year Callaway are introducing the new Quantum range to the market, and true to form, there are five new drivers available.
I’ve got my hands on the new Quantum Triple Diamond Driver, which is the compact low-spinning model, to see how it performs.
First things first, the name Quantum is very ‘Callaway’. By that I mean it’s bold, techy, futuristic, and it fits in pretty well with their previous releases. I don’t love the name, but I think it’s an improvement on Elyte.
Who Is It Aimed At?
The Triple Diamond is Callaway’s lower spinning driver model. It’s usually smaller than the standard head in the range, and as a result it is usually best suited to players with better ability.
For golfers who have a high swing speed, it’s able to lower spin and produce faster ball speeds, as well as more workability.
I also think the Triple Diamond head does look better than the standard Quantum Max this time around, so if you’re struggling to decide between the two, the better-looking head might just give you that extra bit of confidence over the ball.
Unfortunately this does come at a cost, to the tune of £649. That’s a pretty eye-watering figure, and I think you’d have to be pretty certain that it’s going to improve your game if you want to seriously consider purchasing it.
The Tech
The big new technology this year in the Quantum range is the Tri-Force Face. This is made up of three layers of material – high strength titanium, poly-mesh and carbon fibre.
This is a new combination that Callaway says has never been done before, and it’s designed to offer a combination of speed and distance even on off-centre hits.
As always, Callaway’s AI usage comes in here again. The new face has used AI to optimise how it flexes, accounting for the ultra-thin materials working together. The face modelling is tuned to optimise speed, spin, launch and accuracy based on impact patterns for each type of head.
This time around Callaway are offering a 10g weight system, that can adjust for a neutral or fade setup at the back of the head. This differs from the fixed weight system in the Elyte Triple Diamond.
All of this technology is housed in side what the brand are calling their ‘lightest, strongest chassis’ to date. The 360° Carbon Chassis helps to free up weight, improving forgiveness, tightening dispersion and making it easier to position the CG.
The head is built for lower spin, workability and a penetrating flight. It features a deeper face, fade-ready weighting and a 450cc shape.
Callaway Quantum Triple Diamond Driver Review
Looks
As soon as I saw the Quantum Triple Diamond, I preferred the look of it compared to the Quantum Max. The darker colours look a bit more muted and subtle. It doesn’t have the light grey panelling which isn’t quite as premium.
There’s plenty of carbon visible on the head, and plenty of signs of tech too. It can be annoying sometimes that these low-spin heads tend to look smarter and less cluttered than the standard models, because it really tempts me into wanting to use them!
At address these good looks continue. The shaping is a little smaller than the Quantum Max, and there is no chevron for alignment which makes the crown look a bit cleaner.
I was also impressed by the quality of the headcover too. The grey colourway may not have been my first choice, but it feels premium and is easy to take off thanks to the pull-tab at the top.
Feel
Straight away this driver felt solid and fast off the face. The smaller head maybe felt like it was a bit easier to move, and there was plenty of pop when you caught it out of the middle.
As you’d probably expect from a Triple Diamond head there was a more muted sound at impact, something which a lot of good players do prefer.
It’s hard to say whether the Tri-Force face really made a difference in terms of feel as I’ve always got on with the feel of Callaway drivers. I think the TD has a muted sound compared to the Max, so if you’re not looking to attract too much attention this head may help you go a little more under the radar.
Performance
I headed to Clubhouse Golf to test the new Quantum drivers on the Foresight CG Quad. I tried both the Triple Diamond and the Max heads at the same time, to work out which would be best for my game.
First things first, across the board with the Quantum Drivers I saw some really impressive ball speeds.
Triple Diamond drivers aways have a tendency to produce really fast speeds when hit well, and the Quantum TD was no different with an average ball speed of 154.5mph, which is a really good number for me. I was also really impressed by the consistency of the ball speed too, with every shot over 150mph and most within just a couple of mph.
This produced an average carry of 257 yards, and a total of 280 yards. This is a good number, although I do think that there may be potential for more.
A launch angle of 9.5 degrees, and an average spin of more than 2500rpm are probably not quite optimal. These spin rates also prove that the TD drivers are just a bit harder to hit out of the middle, and the smaller head just seemed to launch a bit lower too.
I compared it to the standard Quantum Max, and saw some pretty interesting results.
The Triple Diamond did produce slightly higher ball speeds – albeit with one mis-hit from the Quantum Max. However the Max was producing a lower spin rate and generating a little bit more distance too. The bigger head was just a bit easier to strike, and I saw four yards more total distance.
As you might expect my dispersion with the Quantum Max was a little tighter than the TD, averaging just 11 yards offline compared to 20 with the TD.
Callaway Quantum Triple Diamond Driver Verdict
I really enjoyed using Callaway’s new Quantum drivers and I feel like it is a clear improvement on the Elyte line from 2025. My ball speeds were really impressive – so perhaps the new Tri-Force face is really doing the business here.
The Triple Diamond head is much better looking in my opinion. The darker matte finish on the sole particularly looks sleeker and more premium, compared to the grey on the Max head which is a tiny bit insipid.
A price tag of £649 makes this one of the most expensive drivers we’ve ever tested. Unfortunately that is just where we’re at with the driver market these days, but at least the Quantum TD is full of new technology and new ideas to help your game.
Would I Use It?
I preferred the look of the Quantum TD, but the Quantum Max did give me better overall performance. Decision made.
