A system for every setting
M40 is designed to serve up extraordinary high-resolution stereo sound no matter the setting. It’s ideal as a main audio system in settings where space is at a premium, it’s perfect as a step on the hi-fi ladder for those who don’t want a component-heavy system of hi-fi separates, and it’s the ultimate second-room system. There are no circumstances in which the M40 micro-tower powered audio system isn’t the correct answer.

High-resolution wireless stereo experience
Specified to meet every eventuality, the M40 is able to deliver stunning stereo sound no matter where it’s coming from. On board Bluetooth® 5.0 provides rock-solid wireless connectivity and is compatible with aptX HD and aptX Low Latency technology – so high-resolution sound (up to 24bit/48kHz) can be streamed from any compatible device such as a smartphone, laptop or tablet- and even appropriately specified televisions. Connect the M40 to a computer via its USB input and 24bit/192kHz resolution is available.

A host of connectivity options
M40 has enough inputs to let your games console, your TV, a set-top box, pre-amplified turntable or any other source of sound that takes your fancy join in the high-resolution audio action. You can even attach a subwoofer in case you really want to shake the room. Whatever you want to listen to, the M40 can deal with it, in style. 200 watts of Class D amplification provides the impetus. All you need to do is cue up your favourite tunes and let the M40 bring your music, movies and games vividly to life.

Special grille design
Particular attention has been given to the M40 grille design. Fixing the grille to the baffle, rather than be removable, allows for added strength derived from the baffle and significantly reduces the grille’s structure, particularly around the drivers. The result of the M40’s open grille design minimises disruption of sound dispersion patterns, while reducing reflections for a smoother sonic performance.
