Marshall has spent six decades perfecting the art of being loud on stage, and the brand has done a pretty stellar job in home audio in recent years as well. Party speakers, though, are a newer frontier. Marshall only entered the category in September 2025 with the Bromley 750 (a 52-pound monster), and then followed it up with the smaller (but still $800) Bromley 450 this past spring. Now the lineup finally has a version you can grab on the go with one hand, and it’s called the Bromley 150.
Shrunk Down to Practice-Amp Proportions
At 13.9 pounds and roughly half the size of the 450, the Bromley 150 looks like a little practice amp. Of course, the trademark black PU leather wrap, brass script logo, and knurled knobs are all present as well.
Marshall moved the control panel to the side this time around, freeing up the entire front face for the grille and the warm white stage lights hiding behind it. And in a nod that’ll make gearheads smile, the handle retracts flush into the cabinet so multiple units can be stacked just like proper guitar cabs.
The 40-Hour Encore
Marshall claims 40+ hours of playtime from the swappable LFP battery, and when it finally taps out, a fresh pack clicks in within seconds. And if you need some extra time, a 20-minute charge gets you five additional hours in a pinch.
Two Inputs, Zero Excuses
Flip around to the back and the Bromley 150 is equipped with two XLR/6.35mm combo jacks that will accept mics or instruments. Each one also features its own volume and effect knob, which is perfect for impromptu sets and late-night karaoke sessions.
Everything else runs through physical knobs (bass and treble included), and requires no app to operate. Add True Stereophonic 360-degree sound firing from the front and back, an IP55 rating, and user-replaceable parts down to the grille and corner caps, and this thing is built for backyard jam sessions.
