OVERVIEW
Ultra-compact micro-tower design
At just 71cm high, these petite pillars are compact and discreet. They’ll fit seamlessly into any interior space, and their high-quality finish – available in Black, White and Walnut - will complement any home decor vocabulary. And they do so without compromising on the established Q Acoustics strengths of powerful, precise and engrossing sonic performance.

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.

C3 Continuous Curved ConeTM driver design
The M40 features with the latest Q Acoustics advancement in driver technology: the C3 Continuous Curved Cone™ mid/bass driver. First seen and heard in the award-winning 5000 Series of loudspeakers, C3 (pronounced ‘C cubed’) combines the outstanding bass performance of a traditional straight cone with the high/midrange control and fidelity of a flared cone. The best of both worlds, in other words.
Award-winning cabinet technology
In addition, the M40 features a decoupled tweeter for crisp, pure high frequency performance, along with Helmholtz Pressure Equaliser™ (HPE™) technology to reduce unwanted standing waves inside the cabinet. The cabinet itself is beautifully sculpted, flawlessly finished, and features Q Acoustics’ proprietary Point to Point™ (P2P™) internal bracing to keep the speaker as rigid and inert as possible.
