The CALLISTO 6 C represents the virtues of traditional Hi-Fi wrapped in a convenient wireless audio solution.
We have developed everything from the CALLISTO 6 C drivers to the amplifier 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.
We are pushing the woofer design to new limits of performance, which is possible as we are in total control of the signal path. Leveraging this potential, we elevated the audio performance to levels that surpass almost any speaker amplifier combinations in this price bracket.
The CALLISTO 6 C connects wirelessly to the DALI Sound Hub through an extremely stable digital connection - made on either the 2.4 GHz or the 5.8 GHz band depending on location and quality of the connection. With latency below 25 ms, sync between video and audio from a movie or TV source is obtained well within conventionally acceptable limits.
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.
WOOFER & SMC
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.
We used our experience from developing the OPTICON and RUBICON woofers - combined with a whole lot of listening hours - to optimise the magnet motor to deliver its ultimate. With that knowledge we were able obtain a very linear and perfectly symmetrical suspension within the working area of the voice coil and membrane, only taking control and slowing down the membrane movement at the outermost excursion points.
The extra linearity obtained both around the voice-coil and in the spider manifests itself in reduction in mechanical distortion and less strain on the amplifier, which leads to more detailing and a better defined sound stage.
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.
As a result of these optimisations and especially through use of SMC, the CALLISTO 6 C benefits from an extremely agile, well-behaved and ultra low loss woofer, that when working in conjunction with the amplifier is able to deliver a richly detailed, time coherent and very powerful audio signal.
The CALLISTO 6 C is part of our new 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.
