Marshall has expanded its party speaker lineup in India with the launch of the Marshall Bromley 450, a portable Bluetooth party speaker positioned below the Bromley 750. The new model retains Marshall’s signature vintage-inspired design while introducing a more compact form factor, True Stereophonic 360° sound, an interchangeable battery system, integrated stage lighting, and support for microphones and musical instruments.
The Marshall Bromley 450 features the company’s signature box-style construction wrapped in water-based PU leather, complemented by tactile physical controls, soft TPU corner protectors, and a stamped metal front grille. It also incorporates integrated stage lighting inspired by live concert performances from the 1970s, while a built-in carrying handle improves portability. Marshall says the speaker is designed for durability and repairability, with replaceable components including the battery.
True Stereophonic 360° Sound with Dedicated Amplifiers
The Bromley 450 utilizes Marshall’s True Stereophonic 360° audio technology, allowing sound to be projected in every direction for more consistent room coverage.
The speaker features a multi-driver audio system consisting of:
- 2 x 90W Class D amplifiers powering dual 6.5-inch woofers
- 4 x 55W Class D amplifiers driving four 2-inch full-range drivers
- 2 x 8-inch passive radiators for enhanced low-frequency performance
Marshall says the speaker delivers stereo output with a closed cabinet design and equalizer support. It offers a frequency response of 42 Hz to 20 kHz and is capable of producing up to 100 dB SPL at 1 meter.
The Bromley 450 supports SBC, AAC, and LC3 Bluetooth codecs, along with Bluetooth 5.3 featuring Auracast and multipoint connectivity with a wireless range of up to 70 meters in open environments.
Built for Parties & Live Performances
In addition to wireless music playback, the Bromley 450 includes multiple wired connectivity options suitable for karaoke sessions, DJs, and live performances.
Available inputs include:
- 3.5 mm AUX input/output
- USB Type-C
- RCA
- 2 x XLR / 6.35 mm combo inputs for microphones and musical instruments
Users can independently adjust microphone and instrument volumes, while dedicated controls are available for bass, treble, input effects, media playback, source selection, lighting modes, and battery status.
40+ Hours Playback with Replaceable Battery
One of the key highlights of the Bromley 450 is its interchangeable Lithium Iron Phosphate (LiFePO4) battery, which Marshall says delivers more than 40 hours of playback on a single charge.
Additional battery features include:
- 20 minutes of fast charging provides up to 6 hours of playback
- Full charge takes approximately 3.5 hours
- Supports both AC power operation and battery charging
- Replacement batteries available separately
The speaker also includes a USB Type-C output capable of delivering 5V/3A power for charging compatible devices.
The Marshall Bromley 450 is designed for indoor and outdoor entertainment and carries an IP55 rating for protection against dust and water splashes. Marshall says approximately 15% of the speaker is made using recycled materials by weight. The company has also focused on repairability, allowing users to replace major components to extend the product’s lifespan and reduce electronic waste.
Speaking on the launch, Hanna Wallner, Product Manager, Marshall Group, said, “Last year, we launched our first party speaker and are excited to expand that family of Marshall speakers this spring. The Bromley 450 is a natural continuation and smaller sibling to the Bromley 750. This speaker is more compact and affordable yet still packed with impressive features, including sound that reaches every corner, a stage-light-inspired light show, and our signature Marshall design.”
