Marshall Bromley 750 Bluetooth Party Speaker – Black & Brass

Description

Bring the party to life with the Marshall Bromley 750 Bluetooth Party Speaker in Black & Brass, a powerful portable party speaker designed to deliver immersive, high-volume sound across large indoor and outdoor spaces. The Bromley 750 features Marshall's True Stereophonic 360° sound, using front-, rear-, side-, and up-firing drivers to distribute audio around the speaker. Its powerful acoustic system combines two 10-inch woofers, two 5.25-inch mid-range drivers, two 1-inch tweeters, and two 0.8-inch tweeters, delivering an impressive frequency range of 20Hz–20kHz and a maximum sound pressure level of 127dB @ 1m. For serious output, the Bromley 750 uses two 100W Class D amplifiers for the woofers, two 50W amplifiers for the mid-range drivers, and four 50W amplifiers for the tweeters. Its closed-box cabinet is designed to produce tight, controlled bass, while the Sound Character control lets you adjust the speaker from a more natural sound through dynamic listening and into a high-energy Party Mode. The party atmosphere goes beyond sound. Integrated stage lighting offers three built-in light-show presets that can synchronise with your music, while dedicated microphone and instrument inputs allow you to connect performers, microphones, or other compatible equipment. With 40+ hours of portable playtime, the Bromley 750 is built for extended events. Its rechargeable and replaceable LiFePO4 battery provides up to 5 hours of playback from a 20-minute quick charge, while the speaker can also operate directly from mains power. The removable battery can additionally function as a power bank for charging compatible devices. Despite its substantial size, the Bromley 750 is designed for mobility with integrated wheels, a retractable handle, and side handles. Its IP54-rated construction provides resistance against dust and water splashes, making it suitable for both indoor events and outdoor gatherings. Wireless connectivity comes through Bluetooth 5.3 with Auracast, Bluetooth Multipoint, and a range of more than 70 metres in an unobstructed environment. Wired connections include AUX, USB-C, RCA, and two XLR/6.35mm combination inputs for microphones and instruments. Finished in Marshall's iconic Black & Brass colourway, the Bromley 750 is designed to make a statement — both visually and sonically.
