DALI Callisto 2C Active Bookshelf Speakers | Sound Hub System

Colour: White with DALI Sound Hub

Each of the wireless DALI CALLISTO 2C active bookshelf speakers feature a Hi-Res, cable-free connection to the DALI Sound Hub – the heart of the system. Just plug in the power cord and press ‘Connect’. The sound system makes it easy to stream via Bluetooth and control Hi-Res music from Spotify or Tidal streaming services in stunningly detailed, authentic DALI sound. – You worry about the volume, let us worry about everything else.


Whether you’re listening to music from an online streaming service, a Hi-Res download or a CD/record player, we believe you should hear music as the artist intended. With a host of inputs, from traditional wired connections to Bluetooth Apt-X HD and AAC – plus two future-proof expansion ports (e.g. BluOS) – CALLISTO is ready to connect the way you want it to.


At the heart of the system, the DALI Sound Hub brings true no-compromise convenience to music and movie lovers. It transmits Hi-Res audio in true HD quality (24bit/96KHz) to your CALLISTO speakers, while you take control of the hub with your mobile device. The Sound Hub will automatically switch to whichever source is connected and can be hidden out of sight if desired, as the remote control connects via Bluetooth. Add up to 8 Callisto speakers.

MQA Certified

The wireless Callisto system is now MQA Certified by MQA Ltd. This applies to all products in this series, when the optional BluOS NPM-1 plug-in module is installed. MQA’s award-winning technology captures 100% of the original recording and packages it in a file small enough to stream. When streamed by BluOS to the wireless Callisto speaker through the no-loss fully digital audio transfer, every little detail in the MQA file will find its way to the ear of the listener.


Designing a ‘best in class’ active speaker system is the sum of many parts. One truly important part is the amplifier, or more correctly the amplifier module. Any quality amplifier module consists of three equally important parts that need to be designed to work together in perfect harmony: the amplifier itself, the PSU and the signal processing. The delivery from the signal processing and the PSU to the amplifier circuitry must adhere precisely to the amplifiers needs and demands. Only in this way can you achieve an undistorted, uncoloured and coherent amplification.

Callisto's Class D digital amplifier is based on patented state-of-the-art technology with a global feedback and self-oscillating design chosen for its very musical properties. Being able to deliver 250 Watts for up to 5 seconds, there is plenty of power to ensure more than enough sound pressure even in complex musical passages or massive explosions in movies.
