With its compact yet powerful design, the Bromley 150 expands on Marshall’s goal to elevate listening arrangements of every kind. This 200-watt portable powerhouse is your all-in-one solution for party-monster performance of every kind, from the dimensional detail of its True Stereophonic 360º sound and integrated stage lights to its 40-plus-hour battery life and IP55-rated, dirt- and splash-resistant exterior. Concealed within the rugged, stylish housing are 3 Class D amplifiers driving a 6.5-inch 40-watt woofer, dual 2-inch 6-watt full-range speakers, and a 7.5-inch passive radiator. For Sweetwater’s party professionals, the Bromley 150’s connectivity capabilities are the speaker’s secret weapon — wired, wireless, and mic- and instrument-level inputs ensure you’ll never miss the opportunity to bring massive, high-fidelity sound to any space, with style. From the living room to the basement to the backyard, Marshall’s Bromley 150 is ready to take center stage with unforgettable performance.

Powerful and portable

The Bromley 150's rugged, compact design pulls no punches, guaranteeing the speaker’s aural delivery is ready to roar anywhere. Its side-mounted interface harkens back to the aesthetics of the company’s historic amplifiers, with each knob featuring a backlit design that provides instant, real-time visualizations of every parameter, as well as Clip indicators for each of its two input channels. In addition to track and audio-source management, the Bromley 150 features a 2-band EQ, per-input Volume controls, a range of adjustable Delay and Reverb effects, a battery-life readout, and the ability to toggle between a trio of integrated stage-lighting modes. Plus, a customizable M-button puts a strobe burst at your fingertips and lets you reassign a custom action in the Marshall Bluetooth app. Rounding out this portable party dynamo is a built-in handle at the top of the speaker, allowing you to carry the Bromley 150 anywhere.

A host of party-primed connections

Connectivity-wise, Marshall’s engineers thought of everything. Beyond the wireless flexibility of multipoint and Auracast-equipped Bluetooth 5.3, the Bromley 150 offers a slew of wired options to accommodate any kind of party or event, from microphones and instruments to phones, laptops, and more. A 2-way USB-C port is joined by 3.5mm aux options for audio input and daisy-chain-capable output. What’s more, dual combination jacks support both 1/4-inch and 3-pin XLR connections, ensuring every party setup is poised for premium performance. Additionally, the rechargeable battery includes a quick-charging option that gives you 5 hours of full-powered playback in just 20 minutes, along with a removable silicone cover to protect the battery and inputs. Finally, when you need to make fine adjustments, the iOS and Android Marshall Bluetooth app is at your service with numerous in-depth audio and speaker settings.
