Description:
The Marshall Stockwell III almost sounds as luxurious as it looks, and boasts almighty power for its size.

FULL STORY ======================================================================Marshall
Stockwell III review Seven years after its predecessor came to market, the Marshall Stockwell III is here and wow, what a beauty.

From the moment I unboxed the Stockwell III, I was struck by its quality. Its striking amp-inspired aesthetic, complimented by luxurious PU leather, golden detailing, and a red velvet-infused handle made it likeable from the off. But could its sound live up to its enticing looks? Well, Ive spent hours upon hours listening to music and messing around with various features on
Marshalls new speaker, and Ive got a fair few thoughts. So heres whether it can compare with some of the best Bluetooth speakers around. Latest Videos From TechRadar Watch full video here:

Lets start with sound quality, an area where the Stockwell III is aiming to make quite the leap from its predecessor. Under the hood, youll find one three-inch woofer with 65W class D amplification alongside two 1.75-inch wide-band drivers, which both have 31W of class D amplification. This means that the Stockwell III is incredibly mighty for a speaker of its size, and offers considerably meatier audio than its predecessor could.

The Stockwell IIIs impressive power really shines through in its performance it displays a striking level of confidence with regimented, intent-filled bass, driven mids, and expressive highs that make it an incredibly enjoyable speaker to use. (Image credit: Future) Marshall Stockwell III at Smart Home Sounds for 199.99 In Home Meeting by Sadao Watanabe, I was impressed with the fluent and colorful leading sax, which played alongside substantial and weighty funky bass and accurate, precise drums in the treble range. As the track built towards its climax, the Stockwell III managed the swathe of instruments with ease, and backing vocals, guitars, horns, and bass all came together in a cohesive yet nuanced ensemble.

With a deeper track, like Vision of Love by Lewis Taylor, the Stockwell III proved that its power goes a long way. Pumping deep bass pounded through our music testing room with intensity, yet remained controlled and clean. Energetic drums high up in the frequency range also came through with plenty of bite, although neither end of the spectrum overshadowed the finer electronic details in the mid-range.

The Stockwell III can extend down to 54Hz, and although it wasnt capable of the most full-sounding, consuming sub-bass, I still found that it coped decently with ultra-low frequencies. More generally, the speaker does have a bit of a bass preference, and although this may not be to everyones taste, a swift turn of the bass dial can easily get you the sound youre after.

One thing I will say is that although vocals come through clearly on the Stanmore III, they perhaps lack the warmth and texture that youll find from some other premium speakers. To be clear, I still found that vocal-focused tracks sounded great on the Stockwell III, but audiophiles may wish for a bit more detail and depth.

As youd expect with a recent Marshall release, there's USB-C audio onboard
for lossless playback, and the speaker sounds great with a wired connection. Theres also a 3.5mm port if youd prefer. Unfortunately though, theres no LDAC for higher-res Bluetooth playback something we recently saw on the Marshall Acton IV and Marshall Stanmore IV which wouldve been nice to see.

But a couple of features really help the Stockwell III perform at an
excellent level. For example, Dynamic Loudness helps the speaker maintain clarity, even at higher volumes, and I found that the Stockwell III still sounded excellent even when pushing volume up to 90% and beyond. Marshall has also implemented its True Stereophonic 360 sound, intended to make sure it sounds excellent from every angle, and this felt effective to me, resulting
in the speaker having no true sweet spot ideal for a party situation, say.

One final thing worth pointing out about sound, is that the Stockwell III technically outputs in stereo. However, the stereo effects arent particularly convincing in part due to the Stockwell IIIs limited confines. (Image

department. But how does it fare elsewhere?

Well, when it comes to features, there are quite a few options to uncover.
For the moment, the Stockwell III is using the older Marshall Bluetooth app, unlike the newer Marshall software harnessed by the Acton IV, Stanmore IV,
and Heston soundbars . This means that you only get a five-band EQ, though this still works well and the speaker does sound great out of the box.

The app also enables you to use a soundstage mode to reduce or expand the width of sound, you can toggle on Source Mix to play media via wired and Bluetooth connections simultaneously, and you can map a specific EQ configuration to the speakers M button. In addition, theres a placement compensation feature that genuinely makes a difference, as well as USB-C port configuration settings (you can make it charge other devices, play media, or both), and battery preservation options.

Speaking of battery, the Stockwell III is capable of providing 40 hours of playback double what its predecessor could manage. Thats a phenomenal amount of playtime for a speaker of this size, and a seismic technological advancement, proving that Marshall are still one of the leading audio manufacturers when it comes to battery life.

Ive spoken a bit about design already, but the Stockwell III is a true joy to behold. Its also a lot lighter than Marshalls alternate mid-weight speaker, the Marshall Middleton II, making it feel way more portable. It's also got more amplification power than the Middleton II and in my view, looks more premium its the better mid-weight option overall in my view.

However, this does come at the expense of weaker waterproofing the Middleton II is IP67 rated, whereas the Stockwell III is only IP55. That's still an improvement on its IPX4-rated predecessor and keeps it protected against splashes and dust ingress, but a lot of competitors shield their devices against full underwater submersion.

But lets wrap up now. At $249.99 / 199.99 / AU$379, the Stockwell III isnt
the cheapest option on the market, but for its power, and its sound and build quality, it's an excellent value for money choice. At launch, the Stockwell
II was priced the same as this new model in the US, but it's actually cheaper in the UK and Australia than its predecessor was at the point of release.
With the improvements in acoustics, build, and waterproofing, thats amazing
to see.

Although the Stockwell III leaves out LDAC and is using the older Marshall Bluetooth app at the moment, I still think its a brilliant speaker. With confident yet elegant sound, amazing looks, and a fantastic feature-set, it's the best mid-weight Marshall speaker you can buy, and stands as a stellar upgrade over the Stockwell II. (Image credit: Future) Marshall Stockwell III review: price & release date Priced at $249.99 / 199.99 / AU$379 Released in August 2026 The Marshall Stockwell III was released in August 2026, seven years after the Marshall Stockwell II came to market. It's priced at $249.99
/ 199.99 / AU$379, meaning that in the US it costs the same as the Stockwell II did at launch, and it's actually cheaper in the UK and Australia. Considering the vast improvements it provides, that makes it a phenomenal value for money option. Its available in Black and Brass or in Cream.

You want a super-stylish speaker The Stockwell III is a gorgeous speaker
with enticing PU leather, golden detailing, and a stylish handle. If you want style that matches substance, this is a great option.

You want a powerful yet portable speaker The Stockwell III is crammed with plenty of amplification power, but it's still highly portable and relatively lightweight. Thats the main reason Id pick it over a model like the Marshall Middleton II. Dont buy it if

You want a speaker with higher-res Bluetooth codecs Although the Stockwell III features USB-C audio and a 3.5mm input, it skips on aptX and LDAC. The latter has been seen on a few of Marshalls recent releases, so it wouldve
been great to see on the Stockwell III.

You want the ultimate waterproof speaker The Stockwell III is protected from dust ingress and water splashes, but there are rivals with even better waterproofing on the market. For instance, the Bang & Olufsen Beosound A1 3rd Gen has an IP67 rating, meaning it can be submerged under a meter of water
for up to 30 minutes. Marshall Stockwell III review: also consider Swipe to scroll horizontally Header Cell - Column 0
