DALI CALLISTO 2 C
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 6½” low-loss wood fibre woofer, hybrid tweeter module, and the perfectly balanced internal cabinet volume form the base of a highly accurate audio experience.
As part of our wireless CALLISTO ecosystem, 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.
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 the driver, the DALI acoustics team was able to elevate audio performance beyond conventional speakers.
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.
The wireless CALLISTO system is now MQA Certified by MQA Ltd. This applies to all the DALI CALLISTO products when the optional BluOS NPM-1 plug-in module is installed.
Like its larger sibling, the CALLISTO 2 C features DALI’s innovative hybrid tweeter module, which was optimized specifically for the CALLISTO series. Combining a dome and ribbon tweeter for the astonishing rendering of high frequencies, and a dispersion of high frequency audio that outperforms all other tweeter technologies.
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 amplifier’s needs and demands. Only in this way can you achieve an undistorted, uncolored 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.
At our large woodworking facility in Denmark, we precision-cut the CALLISTO 2 C MDF cabinets ourselves to maintain the high quality, followed by applying the vinyl.
The CALLISTO 2 C cabinet is constructed from 25mm solid MDF, which employs a very rigid construction with robust bracings across the inside of the cabinet for extra reinforcement. This contributes to stiffness and density that practically eliminates resonance within the cabinet. At the same time, great care is taken not to reduce the internal volume of the cabinet unnecessarily.
The mounting of the drivers and the final tests and approvals on each and every speaker is also handled directly at our own assembly lines in our Danish factory.
Through strict in-house control of every aspect of production, CALLISTO achieves a level of fit and finish typically found only in products well beyond its price point.
