Marshall Bromley 750 Portable Party Speaker – True Stereophonic 360° Sound | 40+ Hours Playtime | Built-in Lights & Wheels

The Marshall Bromley 750 delivers the ultimate balance of power, clarity, and portability in one striking design. Built to command attention at every gathering, it defines what a modern party speaker can be — bold, dynamic, and ready for any environment with its immersive 360° sound, extended playtime, and brilliant stage lighting.

Iconic Design with Road-Ready Build

Dressed in Marshall’s classic Black and Brass finish, the Bromley 750 commands presence while remaining practical for every occasion. Its rugged closed-system cabinet, IP54 dust and splash resistance, and built-in handle with wheels make it just as comfortable rolling into a field as it is taking center stage indoors.

True Stereophonic 360° Immersive Sound

Engineered with True Stereophonic multi-directional sound, the Bromley 750 surrounds you with music from every angle. Side-firing, front, rear, and up-firing tweeters create a wall of clear audio and deep bass — ensuring the party sounds equally alive whether you’re at the center or along the edge.

Adjustable Sound Character for Every Party Mood

Fine-tune your vibe with the Sound Character Control knob that lets you switch between “Dynamic” and “Loud” profiles. Switch seamlessly from a laid-back acoustic evening to high-energy peak-hour beats, all without distortion and always with total control over your audio output.

Light Up Every Beat

Add atmosphere to your sound with integrated stage lights that pulse to the rhythm of your tracks. Choose between three preset light modes right from the top panel — each designed to turn your space into an instant concert setting. Wherever the music leads, the Bromley 750 makes it unforgettable.

Epic Battery Life and Charging Flexibility

Equipped with a rechargeable and replaceable LFP (LiFePO₄) battery, the Bromley 750 keeps the energy going for 40+ hours of playback. A quick 20-minute charge gives 5 hours of music, while a full recharge takes only 3.5 hours. Swap in a backup battery or plug it in via USB-C or AC mains for nonstop entertainment.

Connectivity and Controls that Empower

Stay in charge with Bluetooth 5.3 and Multipoint connectivity for simultaneous pairing, alongside aux, RCA, USB-C, and dual XLR/6.35 mm combo inputs for mics and instruments. Control your setup using dedicated knobs for volume, bass, treble, light modes, and input effects, or pair it with the Marshall Bluetooth app for extended customization.

Durability and Ease of Transport

Built tough yet elegant, this 23.9 kg speaker rolls easily with integrated wheels and retractable handle. It’s designed to travel wherever the beat calls — from your backyard to a music hall. Its IP54-certified protection ensures resilience against rain, dust, and unexpected spills without dampening your sound.
