Expect The Exceptional.

An entire high-resolution wireless audio system, delivering uncompromised hi-fi sound that fits conveniently and seamlessly into your lifestyle.

Key Features

  • High fidelity sound with true wireless connectivity from multiple streaming services: Apple AirPlay 2, Roon, Spotify and plenty more gives access to a planet’s-worth of music.
  • Integrate your TV, turntable, games console and more into your wireless, music-streaming system.
  • Voice control - works with Google Assistant, Amazon Alexa (available early 2021) or Apple Siri for easy voice control.
  • Versatile

    Q Acoustics has designed the Q Active range from the ground up, with the express intent of delivering an uncompromised, versatile high-resolution system that can play music from any source – TV, network music streamer, smartphone, laptop, and even a turntable.  

    A compact central Control Hub configured either for Google “Chromecast built-in” or Amazon “Works with Alexa” (coming 2021) is supplied with each pair of speakers, which allows users to connect to a variety of wired and wireless sources. The Hub can be connected to your home network using ethernet or wi-fi.

  • Sound

    The Q Active range is a true active design, with class D amplification eliminating the need for a bulky external amp or receiver. Q Active 400 speakers feature twin Balanced Mode Radiator (BMR) drive units in an offset configuration that deliver a widescreen sound dispersal and a huge sweet spot: so no matter where you’re sitting in the room, you’ll hear the same rich, detailed and expressive sound from the Q Active speakers.


    Meticulous attention to detail has produced a compact, high-performance system that makes a distinctive visual statement - but every element of Q Active has been engineered to deliver the best performance possible.

    As well as the panoramic, widescreen sound delivered by the BMR arrangement and the deep, controlled bass served up by the carefully specified and positioned subwoofers, Q Acoustics has paid painstaking attention to the way the Q Active 400 cabinet contributes to the system’s outstanding sonic performance.

    ‘Dart’ bracing is in the Q Active 400 cabinet to provide essential stiffness to the cabinet and equally helpful mechanical stability to the rear-firing subwoofer units.
