Marshall Bromley 450: two-minute overview
The Marshall Bromley 450 is the second get together speaker that the audio specialist has launched. It’s a smaller variant of its older sibling, however goals to condense every little thing we like about that mannequin right into a less expensive, extra cellular unit. However simply how nicely can it do this?
Nicely, at first look, the similarities between the Marshall Bromley 450 and its sibling are putting. It has a really comparable amp-inspired construct, it is acquired these basic tactical knobs for controlling quantity, bass, and treble ranges, and it is adorned with the golden Marshall brand. However the similarities don’t cease there.
Its older sibling sits in our information to the most effective Bluetooth audio system round, so unsurprisingly, the sound signature right here is definitely fairly comparable. You get agile and punchy, but heat bass, which actually feels just like the star of the present. However you additionally get controller, expressive highs, paired with decently-detailed mids. Just like the Marshall Bromley 750 earlier than it, it is a great-sounding speaker, and has the uncooked energy required to supply superior audio outside in addition to indoors.
My criticisms of the Bromley 450’s sound are only a few and much between. It doesn’t supply probably the most rippling sub-bass, and I wanted to regulate EQ at times to get vocals to sound their greatest particularly tracks. However these are fairly minor qualms, and that is nonetheless a formidable performer — particularly once you account for this mannequin’s wonderful soundstage, stereo sound capabilities, and ‘true’ 360-degree stereophonic sound tech.
One thing else I extremely price is the Bromley 450’s design. Its premium building — with faux-leather casing, a metallic grille, and golden particulars — is as beautiful because it was earlier than. In the meantime, the included deal with makes it comparatively simple to move, even when it is a hefty mannequin total. The Bromley 750’s wheels and suitcase-esque deal with are gone right here although, which makes this a bit harder to hold over longer distances.
Nonetheless, you get higher safety in opposition to the weather in comparison with the Bromley 750, with this smaller various packing an IP55 ranking. Which means that the speaker is dust-protected, and may stand up to multi-directional water jets, making it a very good match for out of doors use.
You’ll make a number of sacrifices when selecting the Bromley 450 over Marshall’s bigger get together speaker, although. You get much less energy, and thus barely much less omnipresence via the deep bass registers — comprehensible provided that the Bromley 450 covers rather less of the frequency vary. However you additionally lose the sound character management function, which lets you discover the fitting stability between ‘dynamic’ or ‘loud’ audio output.
However nonetheless, you do get fairly sturdy performance from the Bromley 450, all issues thought-about. It has an entire host of connectivity choices, together with XLR/6.35mm slots for karaoke and devices. It helps Auracast for multi-speaker pairing with one other Bromley unit or different Marshall audio system — just like the Marshall Middleton II or Marshall Kilburn III. And it has a replaceable battery which packs an unbelievable 40 hours of playtime, and can be utilized as a conveyable charger.
And if all of this wasn’t sufficient, you additionally get stylish stage-inspired lighting, with three dynamic choices for various vibes. You may also flip these off if you wish to preserve extra battery life.
If there’s one flaw that stands proud to me, it is the Marshall app. It feels underbaked, missing EQ controls or the flexibility to regulate results like delay and reverb. I want you had extra methods to remotely management this unit, particularly if you happen to’re additional away from it and wish to make a fast adjustment to the bass, as an illustration.
However total, there’s an entire lot to like concerning the Marshall Bromley 450. It does a fantastic job at shrinking the 750’s abilities down and replicating them, and it is a luxurious get together speaker in nearly each method possible.
Sure, it comes at fairly the fee, and people on a tighter finances might favor a rival from the JBL PartyBox line. However the Marshall Bromley 450 is sort of a special proposition fully — it’s masterfully constructed, constructed to be a real centerpiece, and brings an air of retro-style classiness that its RGB-laden contemporaries fail to ship.

Marshall Bromley 450 overview: options
- Glorious connectivity choices, together with XLR/6.35mm slots for karaoke / devices
- Phenomenal 40-hour battery life
- Sound character management neglected, app is underwhelming
The Marshall Bromley 450 follows in its bigger sibling’s footsteps with an extremely comparable function suite. So which means you’re getting the fundamentals, like multi-point connectivity, fast-pairing, and companion app assist, though there’s an honest quantity extra to uncover.
Initially, this factor has an entire host of connectivity choices. You’ve acquired Bluetooth 5.3, 3.5mm wired, USB-C, and even RCA inputs. In the event you’d like to make use of this unit as a karaoke machine, then no drawback both. There are two XLR / 6.35mm combo jacks on the highest aspect of the speaker, which you need to use. Once more, there are results you may add, together with reverb and delay if you happen to wanna spice issues up a bit.
One other factor I like concerning the Marshall Bromley 450 is its battery life. 40 hours of playtime is totally unbelievable for a speaker of this dimension, blowing many of the competitors out of the water. However there’s extra. That is really the identical battery used on the Marshall Bromley 750, which means you may interchange them if you happen to personal each models. This additionally highlights Marshall’s heightened efforts within the sustainability subject once more — it is issuing parts that can be utilized throughout a number of models, and are totally replaceable.
The battery may also be used as an influence financial institution to cost up exterior gadgets, reminiscent of the most effective wi-fi earbuds and greatest noise-cancelling headphones.
Another function I appreciated on the Marshall Bromley 450 was its Auracast capabilities. Though extra conventional multi-speaker pairing shouldn’t be obtainable, you may join a bunch of suitable Marshall gadgets collectively utilizing Auracast for much more highly effective and immersive sound. I attempted linking the Bromley 450 up with the Marshall Kilburn III and it labored with out a hitch. I additionally tried linking it with a second Bromley 450 unit — one thing I’ll talk about at size within the ‘Sound high quality’ part.
That is all nice stuff to date, however I do have a number of qualms with the Bromley 450’s feature-set. Initially, I’ve to say that the Marshall companion app feels a bit naked. Though there are some neat bodily EQ choices on the speaker itself — which allow you to alter bass and treble ranges — there’s no method of altering this remotely. The identical goes for the reverb and delay results.
Sure, the app supplies a technique to faucet into Auracast broadcasts, and a few easy customization choices for the ‘M’ button, however that’s about it. Provided that Marshall has rolled out a extra full app for its house theater tech — just like the Marshall Heston 120 and Heston 60 — I’d count on a number of extra controls for the Bromley 450.
On high of this, it was a little bit of a disgrace to see the sound character controls from the Bromley 750 get dropped on this new mannequin. This labored very well on that mannequin, and enabled listeners to tailor audio in direction of a ‘dynamic’ or ‘loud’ fashion. I get it, it is a smaller, cheaper mannequin, however it could’ve been good to see once more right here.
However I wish to be clear: the Marshall Bromley 450 nonetheless has a really succesful set of options. I haven’t even talked about my favourite but, the built-in stage lights. There are three presets: the primary is ambient, suited to an event like a cocktail party or solo listening session; the second is consultant of precise stage lights, with daring and dynamic patterns that sync to your music; and the ultimate preset is high-energy and flashy, meant to create extra of a celebration environment.
All the presets work nicely, and the white lighting is tasteful and stylish — one thing that I can’t say concerning the swathe of get together audio system with loud RGB lighting. The second is my favourite, merely for its authenticity and dynamism, however I used to be glad to see an choice to disable lights for the moments the place you wish to preserve battery life.

Marshall Bromley 450 overview: sound high quality
- Energetic sound that rocks indoor and out of doors areas
- Glorious soundstage and no actual candy spot
- Highly effective bass total, though the darkest depths may hit more durable
I used to be an enormous fan of how the Marshall Bromley 750 sounded, so I had fairly excessive hopes for its lil’ bro. However did it ship? Sure, sure it did.
Let me start by stating the plain: it is a significantly highly effective mannequin. The Bromley 450 harnesses the facility of two 6.5-inch 40W woofers, 4 2-inch 6W full-ranges, and a few passive radiators to make that bass really feel even heftier. The result’s highly effective, regimented sound that travels brilliantly, irrespective of whether or not you’re listening indoors or outside.
When tuning into Timeless by Shinchiro Yokota, I used to be wowed by the impression of mid-bass, in addition to the snappiness of higher-pitched percussion. The speaker’s sense of rhythm and dealing with of dynamics additionally remained spectacular, whether or not I used to be listening at low volumes or cranking issues up in direction of max loudness.
In Morning Wonders – Leo Pol Remix by Kolter, a observe with fairly aggressive drums within the treble vary, the Bromley 450 replicated highs with confidence. There was a handy guide a rough responsiveness and satisfying tone to percussion, even whereas the tune’s intent-filled bass consumed our music testing house.
Because the Bromley 750’s smaller sibling, you’re in fact going to make a number of sacrifices by way of sound. Most noticeably, the Bromley 450 is much less highly effective — but it surely’s additionally much less adept at dealing with the darkest sounds within the frequency vary. As an example, tracks with rippling low bass, like Max Dean’s Fascinator, didn’t fairly have that full-sounding rumble that mightier fashions can muster. Sub-bass is audible in tracks, do not get me improper, and the Bromley 450 can nonetheless attain right down to a strong 42Hz, simply don’t count on probably the most palpable deep bass ever.
One minor factor I observed is that there’s additionally a little bit of compression at absolute peak volumes. That is fairly frequent for Bluetooth audio system, however the Bromley 750 barely confirmed any hints of compression — partially due to its sound character management operate, which helped the speaker sound ultra-clean in ‘Dynamic’ mode.
My complaints run on the market although. Certain, vocals may sound a bit subdued at instances after I listened to voice-led tunes indoors. However two issues: the onboard EQ choices completely solved this situation — I simply needed to flip the bass down two notches; and this speaker is designed for events quite than probably the most detailed, high-fidelity listening.
Total, the Marshall Bromley 450 is a really sturdy performer within the audio division. Its punchy bass, direct-sound, and vibrant treble are nice in fact. However the inclusion of Marshall’s 360-degree ‘true stereophonic’ audio tech additionally helps this unit to face out among the many crowd.
This factor genuinely sounds superior from each angle. It doesn’t matter if you happen to’re in entrance, behind, close to, or far-off from the speaker, it doesn’t have any actual acoustic candy spot. This tech impressed me on smaller audio system just like the Marshall Kilburn III, but it surely was much more putting on a hulking mannequin just like the Bromley 450.
In a product briefing, Marshall additionally defined how the speaker’s full-range drivers are mounted on the 4 sides of the speaker (two on the left, two on the fitting) which retains stereo channels nicely separated for a extra immersive listening expertise.
Another be aware on sound: this factor can attain new heights if you happen to pair it with a second unit through Auracast. I used to be fortunate sufficient to be testing the Bromley 450 concurrently my Future colleague, Nikita, and we determined to mix our two models exterior, through an Auracast broadcast from my cellphone. And the outcomes had been distinctive.
In Felini by Venerus and Marco Castello, I used to be astonished by how absorbing the trickle of flowing waters and strumming of pure acoustic guitars sounded. It actually felt as if I used to be standing entrance and middle at a gig. And with deeper tracks like Chris Stussy’s Breather, I used to be enveloped in pumping, euphoric bass. In fact, you’ll get superior energy with a number of models as nicely — when positioning the speaker on the far aspect of a parking zone, I may nonetheless hear that wealthy bass from the opposite aspect. Spectacular stuff.

Marshall Bromley 450 overview: design
- Elegant Marshall aesthetic is as satisfying as ever
- Tasteful lights and premium bodily controls
- Very hefty, and the wheels are not any extra
Each time that I overview a Marshall product, I really feel like I’m repeating myself. However that’s just because I’m all the time stuffed with reward for the charming retro-style design that the corporate brings to each product. And the Marshall Bromley 450 isn’t any totally different.
Every little thing from the faux-leather casing, via to its metallic grille and golden particulars is a pleasure to behold — simply because it was on the Bromley 750. This can be a dear mannequin, however you do really feel just like the luxurious appears to be like, top quality supplies, and tasteful stage lights assist to make your funding really feel worthwhile.
The golden management panel on high of the speaker can be laid out fantastically, and is extremely simple to make use of. Crimson LEDs symbolize which connectivity possibility you’re utilizing, and tactical knobs can be found to change quantity, bass and treble ranges, and extra. The mic and instrument ports are additionally situated on high of the speaker this time, making it even simpler to get a guitar efficiency or karaoke session underway.
One thing that Marshall Bromley 450 really improves on in comparison with its pricier sibling is its safety in opposition to the weather. You’re getting an IP55 ranking right here, which signifies that the speaker is dust-protected, and may stand up to multi-directional water jets. In observe, this basically signifies that the Bromley 450 is ideal for taking into out of doors areas, and can have the ability to deal with a spot of rain with out situation. Because the Bromley 450 is smaller than its older sibling, and simpler to take outside, this appears like a really sensible design resolution certainly.
However what else is totally different from the Bromley 750? Nicely, probably the most noticeable distinction is the removing of wheels. Yep, it is a wheelless Get together Speaker, and also you’ll should lug it round utilizing the deal with on the aspect of the unit. Now don’t get me improper: the deal with is well-made, however if you happen to’re transporting this factor over lengthy distances, a phrase of warning.
This speaker is actually fairly hefty, coming in at 26.9lbs / 12.2kg. Certain, the 750 was basically double the load, however its suitcase-style deal with and wheels made it pretty painless to lug about. In the event you’re conserving your speaker in a single place, or solely transferring it over brief distances, the deal with will definitely suffice, however its weight is value conserving in thoughts.

- Repairability makes the speaker really feel like a worthwhile funding
Let’s not beat across the bush right here. The Marshall Bromley 450 is an costly mannequin, even when you think about its output energy and sonic abilities. However a excessive worth doesn’t imply a speaker can’t be good worth for cash.
And I do suppose you get bang in your buck total with this mannequin. At $799.99 / £549.99 / AU$1,079, the Bromley 450 is costlier than equally powered rivals, just like the JBL PartyBox Stage 320, as an illustration.

- Used alone and whereas paired with a second unit through Auracast
- Predominantly examined utilizing Tidal
I spent hours listening to music on the Marshall Bromley 450, throughout which period I exhausted its varied options and tried it each indoors and outside.
When listening to tunes, I made certain to check out all kinds of genres, and run via tracks within the TechRadar testing playlist. For probably the most half, I used Tidal to blast my tunes, however I additionally dipped into Spotify at times. I used the Bromley 450 by itself to start with, however I additionally had the chance to pair it with a second unit, and related the 2 collectively through Auracast.
Extra usually, I’m an skilled audio gear reviewer, and have spent the final two years testing every little thing from premium headphones — just like the Sony WH-1000XM6 — via to among the greatest Dolby Atmos soundbars, together with the LG Sound Suite Immersive Suite 7 Professional.
