Here is a link for the Acton II Bluetooth manual, https://support.marshallheadphones.com/hc/en-us/articles/360000459618-User-Manual-Acton-II-Bluetooth Now... Assuming average wall insluation, sound proofing and room acoustics... and assuming you're not looking for drunk party level loud but still fairly loud... Setting it up couldn't be simpler, you just need to plug it in and connect your phone to it through your Bluetooth settings. You can also connect to the speaker using a 3.5mm audio cable although you will need to buy your own because there isn't one included in the box.

I think one of the reasons for that is Marshall's portable speaker Kilburn II. It's just as large as the Acton II. Stanmore II, on the other hand, is twice as big as the Acton II, and is more of a small shelf speaker. La qualité sonore est incroyablement parfaite ! Les basses et les trebles sont modifiables et la personnalisation de l'égaliseur est disponible directement sur l'application .Marshall has its own Bluetooth app for both Android and iOS devices which you can use to personalize or customise your music experience. Battery: It's hard to argue with the Marshall Acton's gorgeous styling and equally attractive sound quality, and the detail in the brass knobs and brushed gold-metallic panel gives the Acton enviable wow factor. The myriad connectivity options are also impressive, in particular the choice to play music through either the Marshall Multi-Room hub app, or from a phone through Spotify or the native music apps on Apple and Android devices. One of the most iconic audio brands ever, Marshall’s success all really started with their amplifiers, which have been a top choice for musicians the world over for decades.

The Marshall Acton II is relatively small. Yet when you power it up and hear that initial guitar strum to denote it’s ready to play, it threatens plenty of grunt. Once you crank the volume up a little, along with the bass, you realise how much power is at your disposal. Even if RCA wasn't another deal on the table when deciding between Acton and Stanmore, I'd still get the Stanmore... With that in mind, Zound's decision to put not just a Marshall logo on the Acton, but also the associated retro styling, makes a lot of sense. Being louder, The Kilburn II will provide a more saturated experienced however the Acton II is capable of this as well.When connected, you will know Alexa is awake by the illumination of the speaker’s five blue LEDs across its front panel, while its far-field voice recognition means you shouldn’t have to scream commands from the other side of the room.

The Kilburn II offers multi-directional sound which the Acton II doesn't, the Acton II only has forward facing speakers. I'm not saying you'd better ditch the decibel rating completely, because you shouldn't. It does have its place. But in this subject case, there's no comparison between the Acton and the Kilburn.

We're also not completely convinced by the concept of a Marshall multi-room system; you might buy one iconic-looking Marshall speaker, but wouldn't two, three for four look a little odd in your home? Which means that the difference between 101 vs 98 dB is MUCH more than the difference between, say, 83 vs 80 dB.

Malgré son petit format, elle ne manque pas de caractère et offre un son stéréo colossal.Via the control knobs, the bass and treble levels can be manipulated to suit your taste and room. This is a nice touch, and the ability to use physical controls means that fine-tuning on the fly is an easy task. Having said this, don’t expect the controls to completely alter the sound; think of them as tweaks, rather than drastic alterations.
