Following the success of the M20 bookshelf speakers, the Q Acoustics M40 offers a significant power and sound quality boost in a stylish floorstanding 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.

The Q Acoustics 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 HiFi ladder for those who don’t want a component-heavy system of HiFi 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.


  • Powerful: The Q Acoustics M40 are powered by 200W of Class D digital amplifier with 2 x 5" drivers and 2 x 0.9" tweeters. The frequency response is untouchable at this price point meaning you get exceptional depth and bass and crystal clear clarity.

  • Wireless Streaming:  Stream CD quality audio wirelessly from any Bluetooth-enabled device, giving you the freedom to enjoy your favourite music without the hassle of wires.

  • Analog Inputs: The M40's feature a 3.5mm AUX input and an RCA audio input allowing you to connect your record player, CD player or radio tuner.

  • USB Input: Connect your M40 to a computer or WiFi streamer such as the WiiM Pro, via USB and 24bit/192kHz studio-quality sound can be yours.

  • Connect Your TV: Connect your TV with the optical audio input and level up your TV, movies & gaming.

  • Remote Control: Control your audio playback with ease using the included wireless remote, providing convenient access to volume and playback controls from the comfort of your seat.

  • Subwoofer Outputs: Whilst the M40's pack a serious punch right out of the box, if you want to take it to the next level again you can connect an external subwoofer to the dedicated subwoofer outputs, adding depth and richness to your sound.
