Marshall's ridiculously powerful party speaker will make you feel like a rock star – and I reckon you'll need a roadie, too

• The Marshall Bromley 750 launches for $1,299 / £899 / AU$1,799 in September 2025
• 500W of Class D amplification and "stage inspired" lighting
• 40 hours of battery life, IP54, and wheels to help move it around

Marshall has announced its first ever party speaker, and it could be the most realistic Marshall amp experience from its wireless speakers yet. The new Bromley 750 is very big and very loud.

Like many of Marshall's stage setups, this speaker comes on wheels, but unlike the OG amps this one doesn't need to be placed near a power outlet, because it has a huge replaceable battery that can deliver over 40 hours of audio. And it's got integrated "stage-inspired" lights offering ambient and more energetic lighting.

In addition to being a party speaker, the Bromley 750 can actually also act as an amplifier for your instrument: it has two XLR/6.35mm combo inputs as well as its 3.5mm, USB-C and RCA inputs; there's also Bluetooth 5.3 with Auracast. And with IP54 dust and water resistance it should be able to handle even a hostile audience.

This one goes up to eleven

The Bromley 750 has as many speakers as a guitar hero's Marshall stack, although here they're of different kinds: two 10-inch woofers, two 5.25-inch mid-range drivers, two 1-inch tweeters and two 0.8-inch tweeters. That enables the device to cover a frequency range of 30Hz to 20,000Hz.

Where Spinal Tap's Nigel Tufnel wanted his Marshall to go one louder than normal amps, the Bromley goes even further: the Bromley 750 has two 100W Class D amps for the woofers, two 50W amps for the mid-range drivers and four 50W amps for the tweeters. That's the kind of power even Slipknot's Jim Root might consider a bit much.

That means this is the first Marshall speaker that should really make you feel like you're a rock star; as much as I like Marshall's portable Bluetooth speakers, they're just physically too small to give you the same propulsive push as a too-big amp too close on a too-small stage. This, on the other hand, is likely to blast you through the wall at the first power chord.

That power does mean you're also likely to experience a less-welcome aspect of the Marshall amp experience, though. If you've ever had to lug a 4x12 speaker cabinet five floors up a fire escape, you'll know why famous musicians prefer to let roadies do the lifting.

At a hefty 23.9kg this is pretty heavy – not quite as heavy as a Marshall speaker cabinet, but three times heavier than Marshall's previous biggest Bluetooth speaker, the Woburn III. In guitar terms, it's equivalent to around 10 Gibson Flying Vs.

The Marshall Bromley 750 will be available from 23 September 2025 on Marshall.com in the UK, with retailers following on 30 September. US and Asia-Pacific pre-orders begin on 26 September; in the rest of the world you can sign up to be notified when pre-orders become available.

It's far from cheap, with an official price of $1,299 / £899 / AU$1,799 – but there's no denying you get plenty of power for that price.
