The Marshall Bromley 750 is a party speaker with a welcome identity crisis£900 / $1,300 / €1,000, marshall.com
From Woodstock to Wembley, Marshall amplifiers have soundtracked six decades of live music. Now the iconic British brand has launched the Bromley 750 party speaker — but this isn’t just another Bluetooth boombox with delusions of grandeur.

Where most party speakers chase RGB light shows and smartphone integration, Marshall has approached the Bromley 750 like a portable PA system that happens to connect wirelessly. Can a £900 party speaker genuinely handle professional duties for mobile DJs, street performers, and event organisers? After putting it through its paces, the answer is surprisingly emphatic: this thing absolutely delivers.
Design & build: gigging gear with Marshall DNA
The Bromley 750 looks unmistakably Marshall. That signature brushed metal control panel, faux-leather wrap, and stamped metal grille announce its heritage before you’ve played a single note. Unlike Marshall’s lifestyle speakers, this isn’t designed to sit prettily on your bookshelf — it’s built for the road.
At 23.9 kg, it’s undeniably got heft, so Marshall has sensibly given it integrated wheels and a built-in handle for tilt-and-roll transport, transforming it into something closer to flight-case luggage. Anyone who’s lugged traditional PA speakers up venue stairs will appreciate the practicality here. Side-mounted handles make getting it in and out of car boots straightforward enough.

The IP54 rating proves crucial for professional outdoor work. Dust and splash resistance mean moody weather won’t derail your gig, while the drainage system around the top tweeters ensures any moisture that does get in won’t cause grief. After testing in the rain, the speaker continues performing without complaint.
One genuinely brilliant feature: the exchangeable battery doubles as a power bank. Charge your phone between DJ sets or keep essential gear topped up during all-day festivals. It’s practical thinking that shows Marshall consulted actual working musicians during development.
Sound & performance: 500 watts that know how to behave
The Marshall Bromley 750’s 500W Class D amplification system drives eight speakers: two 10-inch woofers, dual 5.25-inch mid-ranges, and four tweeters. All this is enough to hit gig-worthy levels of 127 dB from a metre away.
But raw power without control is just noise. What impresses me most is the Bromley 750’s composure across different scenarios. The 360° True Stereophonic sound proves transformative for street performances where audiences gather around you, eliminating the traditional PA problem of strategic speaker placement.
The real secret weapon is the Sound Character control. Twist it towards Dynamic and you get detailed, controlled output perfect for acoustic sets or indoor corporate events. Swing it to Loud and the Bromley 750 prioritises maximum impact for outdoor festivals, warehouse parties, or cutting through traffic noise during busking.

This adaptability makes the Bromley 750 remarkably versatile for working musicians. One speaker handles intimate restaurant gigs on Friday, outdoor markets on Saturday, and raves on Sunday. Compare that to owning separate PA setups for different venue types.
Bass extends down to 30 Hz — proper sub-bass territory, electronic music DJs will appreciate. During outdoor testing, low-frequency content remains tight and defined even at high volumes, while the quad-tweeter array keeps highs crisp without harshness. The frequency response stays remarkably consistent across the volume range, avoiding the distortion plague that afflicts cheaper party speakers.
The onboard two-band EQ (bass and treble) provides quick adjustments without menu diving. Some may miss dedicated mid-range control, but for most live scenarios, the combination of Sound Character switching and two-band EQ covers essential tonal shaping.
Marshall Bromley 750’s pro features: XLR inputs mean business
Here’s where the Marshall Bromley 750 separates itself from consumer party speakers: dual XLR/6.35 mm jack combo inputs with individual gain controls. For buskers, open mic hosts, mobile DJs, or wedding musicians, these inputs are essential.
Input one handles microphones, although there’s no phantom power on board. Tested with a dynamic mic, the preamps deliver clean, usable gain without noticeable noise. The onboard delay and reverb effects add polish to live vocals — though they’re practical tools rather than studio-grade processors.
Input two accepts instruments, such as acoustic guitars, keyboards, and even DJ controllers (via the alternative, RCA inputs). Combined with Bluetooth playback, you can genuinely run small performances from this single unit — with backing tracks through Bluetooth, plus live vocals and instruments through the combo jacks.
One limitation: the EQ controls don’t affect the XLR inputs, only the main Bluetooth/auxiliary signal. Some performers will find this restrictive.

The integrated stage lighting deserves mention. Three presets range from ambient mood-setting to fully reactive modes that sync with music. Unlike tacky RGB light bars, Marshall’s kept things classy with bright white stage-inspired aesthetics. The strobe burst triggered via the M-button adds drama to DJ performances without looking cheap.
That 40+ hour battery life? Genuinely game-changing for multi-day festivals or long wedding receptions. During testing, a full weekend of intermittent use barely dents the charge. When power does run low, simply swap in the (optional) backup battery, or connect to mains power to a avoid interrupting playback.
Additional connectivity covers most scenarios: USB-C audio, 3.5mm auxiliary in and out, plus RCA inputs. Bluetooth 5.3 includes Auracast broadcasting to futureproof any multiroom dreams. And yes, you can either daisy-chain multiple Bromleys via an aux connection or enable Auracast for an even bigger wall of noise.
What’s missing? The lack of aptX or LDAC may disappoint some, while DSP presets for different music genres would add versatility. The Marshall companion app is also uncharacteristically sparse — no EQ or Sound Character adjustments. At worst, it means using the ample physical controls; at best, a firmware update will add functionality.
Should I buy the Marshall Bromley 750?
At £900, the Marshall Bromley 750 positions itself against entry-level PA systems rather than consumer party speakers. That pricing makes sense when you consider what’s included: professional XLR inputs, 40-hour battery, IP54 weather protection, and 500 watts of power.
Buy the Bromley 750 if you’re a mobile DJ working multiple venue types, a busker needing reliable amplification, or a musician handling small weddings and corporate events. The Sound Character control and XLR inputs justify the premium, while that phenomenal battery life eliminates charging anxiety during multi-set days. Plus, on days off, it’ll look absolutely mint sitting in the corner of your pad.

Don’t buy if you need traditional PA features like multi-channel mixing and per-channel EQ, or simply want maximum value per watt. Dedicated PA gear still wins on ultimate flexibility, while consumer party speakers undercut significantly on price.
The Marshall Bromley 750 brings professional audio thinking to the consumer party speaker category. It’s not the cheapest way to amplify your gig, but it might well be the most versatile single-box solution available.
Whether you’re DJing rooftop parties, playing acoustic sets in beer gardens, or hosting karaoke nights, this speaker adapts brilliantly. The rock ‘n’ roll looks? That’s just the encore.
