PRODUCT DETAILS
As part of our wireless CALLISTO eco system, the stand mount CALLISTO 2 C represents the virtues of traditional Hi-Fi merged with the convenience of wireless audio. Designed to deliver on DALI’s promise of producing the most natural and faithful reproduction possible.
The CALLISTO 2 C is 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.
The CALLISTO 2 C 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.
MQA Certified
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 unique 6½" CALLISTO 2 C woofer takes 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.
SMC
The CALLISTO 2 C woofer 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 2 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.
OVERVIEW
The CALLISTO 2 C is the stand mount solution in our new wireless ecosystem that empowers you to easily access all your Hi-Res music directly from your smart device. Connect via Bluetooth (AAC/AptX HD) or the optional BluOS module (Wi-Fi). The CALLISTO 2 C is the perfect choice for smaller rooms without giving up performance. The combination of our 6 ½" low-loss wood fibre woofer, hybrid tweeter module and the perfectly balanced internal cabinet volume form the base of a highly accurate audio experience.
