Marshall’s First-Ever Party Speaker Is for People Who Hate Party Speakers

Most party speakers are exercises in compromise — decent sound wrapped in RGB light shows designed to distract from mediocre engineering. Marshall’s first entry into this space, the Bromley 750, takes a different approach entirely. Instead of chasing the aesthetic trends that define this category, they’ve simply scaled up their amplifier philosophy by prioritizing acoustic performance, building for durability, and making the controls intuitive enough that you don’t need a manual. The result is a $1,299 speaker that sounds more like a guitar amp than typical party gear.

Amplifier Heritage in a Different Package

The visual connection to Marshall’s amplifier heritage runs deeper than just the iconic script logo. Every tactile element — from the brushed metal control panel to the stamped steel grille — borrows directly from the brand’s amp vocabulary. The water-based PU leather wrapping are functional nods to decades of gear that’s been used by the likes of Hendrix and Clapton. But for this party speaker, Marshall hasn’t tried to reinvent their visual language for a younger crowd. Instead, they’ve doubled down on what’s made them recognizable since the ’60s.

The 360-degree “True Stereophonic” sound system uses a meticulous driver arrangement with dual top-firing tweeters that push audio upward and outward. This addresses the biggest pitfall of party speakers, which is maintaining clarity when people are scattered around a space rather than positioned in a sweet spot like traditional speakers expect.

Sound Character That Adapts

The most intriguing feature might be the single knob that toggles between “Dynamic” and “Loud” modes. This sound character control essentially gives you two speakers in one. Dynamic mode optimizes for indoor listening with controlled dynamics, while Loud mode opens everything up for outdoor spaces where you’re competing with ambient noise.

The 40-plus hour battery life is notable too. Most party speakers die after 8-12 hours, right when events are hitting their stride. Marshall’s swappable LFP (lithium iron phosphate) battery system means you can keep a spare charged and swap it out in seconds. The battery also doubles as a power bank, which is a nice touch.

Performance Meets Practicality

The dual XLR/quarter-inch combo inputs set the Bromley 750 apart from speakers that only accommodate smartphones. You can plug in microphones, electric guitars, keyboards, or turntables directly. Together with the built-in reverb and delay effects, this turns the speaker into a portable PA system rather than just a playback device.

The IP54 rating handles dust and splash protection adequately, though it’s not quite as robust as some outdoor-focused competitors. The integrated drainage system near the top tweeters is a nice touch that shows Marshall thought about real-world usage scenarios.

At 52lbs, portability is relative. The telescoping handle and wheels help, but this isn’t something you’ll casually carry to the beach. It’s designed more for the kind of events where you roll it into position once and leave it there.

The Lighting Situation

Last but certainly not least, the integrated LED array hidden behind the front grille offers three presets — one ambient mode and two that react to music. Marshall kept the lighting relatively subtle compared to the rainbow light shows common in this category. The LEDs are invisible when not in use, maintaining the speaker’s clean aesthetic.
