Bromley 450: to experience True Stereophonic sound at 360°
Designed for lovers of powerful sound and iconic design, the Marshall Bromley 450 stands out as a premium Bluetooth speaker capable of transforming any space into a true musical stage. Inspired by the brand’s legendary guitar amps, it combines an emblematic retro style with impressive modern performance. Compact yet formidably efficient, it delivers immersive 360° sound, ideal for livening up a party, indoors or outdoors. Thanks to its robust design, long-lasting battery and ultra-complete connectivity, it embodies the perfect blend of mobility, power and versatility.
Immersive, versatile sound power by Marshall
The Bromley 450 makes no compromises on audio performance. Equipped with an advanced architecture and 360° sound dispersion, it delivers an immersive experience that fills the space without requiring precise positioning. Its True Stereophonic technology ensures balanced reproduction, with deep bass, clear highs and a wide soundstage.
Designed for festive moments, it can reach high sound levels while maintaining excellent listening quality. Its extensive connectivity, including Bluetooth, mic/instrument inputs and wired ports, makes it a truly versatile audio hub, for music as well as karaoke or live performances.
An iconic, rugged design built for mobility
True to the Marshall DNA, the Bromley 450 features a design inspired by vintage amps, with premium finishes, a textured coating and elegant details. But beyond its aesthetics, it was designed to follow you everywhere. More compact than its big sister, it remains easy to carry thanks to its integrated handle.
Its IP55 certification guarantees excellent resistance to dust and splashes, making it perfectly suited for outdoor use. Add to that an impressive battery life of over 40 hours and a replaceable battery, and you get a speaker ready to accompany your longest events without interruption.
