Marshall Bromley 450 is a powerful standalone party speaker system. The model is positioned as a smaller and lighter version of the flagship audio giant Bromley 750, maintaining the signature vintage style of guitar cabinets and a colossal volume reserve for outdoor use.
Despite being the "junior" model, the Bromley 450 delivers an impressive total power of 400 W thanks to highly efficient class D amplifiers. The configuration includes two 6.5-inch low-frequency drivers (40 W each), four 2-inch wideband tweeters (6 W each), and two massive 8-inch passive radiators. With the signature True Stereophonic technology, the speakers provide full 360-degree panoramic sound, completely eliminating "dead zones" on the dance floor. The frequency range is 40 - 20,000 Hz, and the maximum sound pressure reaches 100 dB, guaranteeing deep, punchy bass and clear vocals.
The 12.2 kg enclosure with dimensions of 366 x 492 x 261 mm is covered in signature artificial leather and protected from dust and water splashes according to the IP55 standard. The front metal grille conceals the main feature of the series - integrated RGB Stage Lighting backlight with a 70s stage show effect that pulsates in time with the music.
On the top brass panel, there are analogue toggles and tone controls. The connectivity options are unique: in addition to modern Bluetooth 5.3 with Auracast support (and LC3 codec), the speaker features RCA, AUX, USB-C ports, and two combined XLR/6.3 mm inputs for direct connection of guitars or microphones for karaoke.
The device is powered by a removable lithium iron phosphate (LiFePO4) battery, providing over 40 hours of autonomy. The battery supports hot swapping and can also act as a powerful power bank for charging gadgets.
