Marshall Keeps the Party Going with it’s Latest Party Speaker – Bromley 450

17th of March 2026 – Marshall grows its party speaker line up with the launch of  Bromley 450. Sporting the same, unmistakable Marshall design as the larger  Bromley 750, this compact portable speaker lets everyone know the party is on thanks to True Stereophonic 360° sound, 40+ hours of playtime and integrated stage lights that make it the center of attention in any setting. 

Every element of the Bromley 450 is designed with purpose. Tactile controls invite interaction, while the durable construction ensures it stands up to heavy use, loud rooms, and long nights. A water-based PU leather wrap encases a premium box design,  with soft TPU plastic corner caps for added durability and a stamped metal grill that sits above integrated lights inspired by ‘70s stage shows. Bromley 450 is guaranteed to stand out – living room, festival, or backyard, this Bluetooth party speaker goes the distance and looks the part. 

Whether the party is indoors or outside, there’s no need to worry about sacrificing sound quality as this portable speaker has True Stereophonic 360° sound that travels far and can be felt in every direction. Bromley 450 can also play free from wires and is dirt and splash-resistant thanks to its IP55 rating. Plus, its convenient size, including a built-in handle for easy transportation, makes it the perfect sidekick wherever the party goes. 

Bromley 450 also shares the same exchangeable battery as Bromley 750 to keep the party going for longer and includes two combo jacks for mic and instrument inputs if the party calls for an impromptu DJ set or karaoke night. 

“Last year, we launched our first-ever party speaker, and we’re excited about growing that family of Marshall speakers already this spring,” said Hanna Wallner, Product  Manager, Marshall Group. “Bromley 450 is the natural continuation and smaller sibling to Bromley 750. This speaker is smaller and more affordable yet still packed with  impressive features, including sound that hits every corner, a stage light-inspired light  show, and our unique Marshall design.” Hanna continued. 

“With Bromley 450, our goal was to take everything we loved about the Bromley 750  and bring it into a more compact form. It delivers the same signature sound: fast,  powerful bass, clean mids, and detailed highs. Thanks to our unique 360° True  Stereophonic design it can always be the center of the party, preserving the depth and atmosphere of your favorite music,” added Malcolm Kennedy, Director of Audio &  Acoustics, Marshall Group. 

Bromley 450 is available at select Digital Walker and open_source stores and Marshall  Official Stores at Shopee Mall and LazMall from March 31st at P42,990.00. Please see below for full specs and further information. 

BROMLEY 450 KEY FEATURES 

True Stereophonic 360° sound: Whether dancing at a house party or festival campsite, the music always feels close with a sound that gets around. Every beat finds its way, no matter the location. Drivers on all sides mean slipping right into dancefloor mode is easy. Just press play to get the party started. 

40+ hours of portable playtime: They say nothing good happens after 2 am, but with  Bromley 450’s long playtime, there’s plenty of time to find out. Made to keep the party going no matter the place, this speaker can play 800 songs back-to-back. Buy an extra battery to keep on standby for when power is running low, or use the AC cable to plug in the speaker. This can also be used to recharge the battery. 

Integrated stage lights: At Marshall, we know what makes for a good light show. Take it back to the best gig memories with three presets that each add to the energy of the party in their own unique way. The first preset creates the perfect ambient lighting to get going to, while the second and third turn things up even more by dynamically moving to the music. Now light up the dancefloor, literally and figuratively. 

Mic & instrument inputs: The most memorable shows are the unexpected ones. With inputs for both mic and instruments, turn the party into an impromptu gig or karaoke session without any hassle, and add that live musical layer to give friends a night to remember. 

Dirt & splash resistant: With Bromley 450’s IP55 rating, it’s easy to pick the next party location. Park, festival, or backyard — dirt and water splashes are no problem for this portable speaker. It’ll keep the party going anytime, anywhere. Taking a bit of a break in between parties? Don’t worry. A bit of dust during downtime won’t hurt it either. 

Built-in handle: Take the party as far as it can go. With its built-in handle, Bromley 450  is easy to bring along, no matter how secret the location. Whether going all out at the beach or setting the mood in the festival camp, just pop it in the trunk of the car or carry it on the train.

MAKING OUR PRODUCT LAST LONGER 

Bromley 450 contains 15% recycled material by weight¹, reducing the need for virgin resources. This helps minimize environmental and social impacts associated with raw material extraction and processing. Using recycled content also helps lower carbon emissions compared to producing virgin materials².

When designing, we prioritize durability, repairability, and replaceable components to extend product lifespan and reduce waste.  Bromley 450 comes with an easily replaceable LFP battery3, featuring adaptive charging technology that helps protect battery health over time. You can purchase replacement batteries at marshall.com. 

1 Includes post-consumer recycled ABS, post-consumer recycled PC-ABS, pre-consumer recycled aluminum alloy, pre-consumer recycled praseodymium–neodymium (rare-earth elements), and post-consumer recycled polyester. Calculations are based on total product weight, excluding accessories and packaging. 

² Industry data indicates recycled materials generally have a lower carbon footprint than virgin materials; actual reductions vary by material and process. 

3Bromley 450 uses a Lithium Iron Phosphate (LFP) battery, free from cobalt and with minimal nickel content (~0.25%). This reduces reliance on some critical raw materials linked to social and environmental challenges. The battery still contains lithium and other critical minerals. Compared to conventional Lithium-Ion (Li-ion) batteries, LFP offers a longer cycle life and enhanced safety, with a significantly lower risk of thermal runaway. The trade-off is that LFP technology is generally heavier and has lower energy density,  which is why Li-ion remains common in devices where weight and compactness are key. For applications where durability and sustainability matter most, LFP is a strong choice. Please recycle old batteries and electronic products.
