DALI CALLISTO 2 C Wireless Powered Speakers
Perfect for smaller spaces or rooms where the speakers need to remain discreet, but where power and presence are still paramount. The combination of a 6½-inch low-loss wood fibre woofer, a hybrid tweeter module and the perfectly balanced internal cabinet volume results in a supremely accurate and powerful audio experience. Connects wirelessly to the DALI Sound Hub through an extremely stable digital connection. With latency below 25 ms, sync between video and audio from a movie or TV source is obtained well within conventionally acceptable limits.
Everything from the drivers to the amplifier is developed in-house, which is why we can optimise every single component to match each other perfectly. This enables us to design the woofers to be more linear than would be possible in a similar traditional passive speaker system.

The DALI CALLISTO speakers are MQA Certified. By adding the DALI BluOS NPM-1 module to your system, you can now take advantage of the ever-growing catalogue of studio master recordings that have been encoded into MQA and streamed on services like Tidal.
Like its larger sibling, the CALLISTO 2 C features DALI’s innovative hybrid tweeter module, which was optimised specifically for the CALLISTO series. Combining a dome and ribbon tweeter for astonishing rendering of high frequencies, and a dispersion of high frequency audio that outperforms all other tweeter technologies.
The dome membrane is very soft and ultra-lightweight, and actually so thin that a coating has to be applied to hold the material together and be uniform in construction. We have optimised the magnet system to maximize flux saturation right at the voice coil area. This optimisation combined with the use of an ultra-thin magnetic fluid for cooling results in better control, power handling and greatly limits distortion.
The ribbon part of the hybrid module is a magneto-static type tweeter. Four bands of conductive material make up the active diaphragm that is controlled by a strong magnetic field formed around it. The ribbon tweeter is the master of wide dispersion, and combining it with the soft dome, we get a tweeter module that can be utilised as low as 2.0 KHz and continues to perform well above 30 KHz. This extreme bandwidth combined with the ultra wide dispersion is an important part of the DALI sonic definition.
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.
The CALLISTO 2 C Class D 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.
