DALI CALLISTO 6 C Wireless Tower Speakers

The CALLISTO 6 C is part of the DALI wireless ecosystem that empowers you to easily access all your Hi-Res music directly from your smart device. Be it via Bluetooth (AAC/AptX HD) or the optional BluOS app. The CALLISTO 6 C delivers a complete and highly detailed three-dimensional sound stage into even large rooms, while adding extra width and depth. The two woofers and large internal cabinet volume ensures truly deep bass performance and room filling sound-pressure levels. All this without the need of complicated electronics.

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.

The CALLISTO 6 C features two 6½” unique woofers which take low loss and linearity to a whole new level. By controlling the entire signal path from source to driver, the DALI acoustics team were able to elevate audio performance beyond conventional speakers.  Every element of the CALLISTO woofer is optimised to work in perfect balance with the built-in amplifier, and because of this, the sound stage created is detail-rich, time-coherent and effortlessly immersive. The result is music reproduced exactly as the artist intended. The CALLISTO 6 C woofers benefit from the use of SMC in the pole piece. When used in a speaker magnet motor system, it results in a significant reduction of distortion from mechanical loss. SMC’s unique ability to deliver a high magnetic conductivity and a very low electrical conductivity delivers all the wanted qualities of a really good speaker magnet without the traditional downsides.

The CALLISTO 6 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
