The Devialet Phantom Reactor 900 is a superb sounding and stunningly elegant wireless active speaker. This stylish smaller sized speaker was modelled off the larger phantom golds but with some added features that include touch sensitive volume controls on the top of the unit, a 3.5mm jack input for attaching analogue devices and the ability to stereo pair without the dialogue unit. They can be used individually or as a stereo pair. With the need for speakers to take up less space in the home but without compromising on high sound quality, the Reactors deliver. They use their own refreshed Devialet app, which looks great and is easy to use and once set you can stream Spotify directly to them. They weigh in at 4.3kg each and the dimensions are: Width: 219 mm, Height: 157 mm, Depth : 168 mm.
