Insights from Marshall Group
Hanna Wallner, Product Manager at Marshall Group, stated, “Following the launch of Marshall’s first party speaker last year, we are thrilled to expand our lineup this spring. The ‘Bromley 450’ is a more compact sibling to the ‘Bromley 750,’ offering compelling features such as room-filling sound, stage light-inspired visual effects, and Marshall’s unique design, all in a smaller and more accessible package.”
Malcolm Kennedy, Director of Audio & Acoustics at Marshall Group, added, “With the ‘Bromley 450,’ our goal was to bring the essence of the ‘Bromley 750’ into a more compact form. Users will experience Marshall’s signature sound with crisp, powerful bass, clear mids, and delicate, expressive highs. Furthermore, Marshall’s proprietary ‘True Stereophonic’ omnidirectional sound design ensures it stands out in any party setting, delivering music with depth and realism.”
