DALI CALLISTO 6 C
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 ensure truly deep bass performance and room-filling sound-pressure levels. All this without the need for complicated electronics.
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 optimize 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 the 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 catalog 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 the driver, the DALI acoustics team were able to elevate audio performance beyond conventional speakers.
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 DALI trademark hybrid tweeter module was optimized specifically for the CALLISTO 6 C. It combines the dome tweeter with a ribbon tweeter for an amazing rendering of the 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 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.
At our large woodworking facility in Denmark, we precision-cut the CALLISTO 6 C MDF cabinets ourselves to maintain the high quality, followed by applying the vinyl.
The cabinets for the CALLISTO 6 C are constructed from 25mm solid MDF, which employ 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.
