Dali Callisto 6 C Wireless Speakers (Pair)
Dali Callisto 6 C is part of Dali's 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 soundstage into even larger 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.
Callisto 6 C represents the virtues of traditional Hi-Fi wrapped in a convenient wireless audio solution. Everything from the Callisto 6 C drivers to the amplifier is developed in-house so each component is matched perfectly. This lets Dali design the woofers to be more linear than would be possible in a similar traditional passive speaker system. Leveraging their total control of the signal path, they elevated the audio performance to levels that surpass almost any speaker amplifier combinations in this price bracket.
Dali Sound Hub
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.
Touch Sensitive Volume
The touch-sensitive panel atop the Callisto speaker cabinet lets you control the volume at the touch of your fingertip. The included Bluetooth remote & the Sound Hub's volume knob gets the job done just as easily. Regardless of your approach, the actual volume change is done at the very end of the signal chain.
The Callisto woofers benefit from patented Soft Magnetic Compound (SMC) in the pole piece. The result is an extremely agile, well-behaving, ultra low-loss woofer with a significant reduction of distortion from mechanical loss.
Wood Fibre Cones
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, Dali is 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 soundstage created is detail-rich, time-coherent and effortlessly immersive.
The result is music reproduced exactly as the artist intended. The extra linearity obtained both around the voice-coil and in the spider manifests itself in a reduction in mechanical distortion and less strain on the amplifier, which leads to more detailing and a better-defined soundstage.
Dali trademark hybrid tweeter module was optimised 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 HF audio that outperforms all other tweeter technologies. The magnet system is optimised to maximise flux saturation right at the voice coil area. This optimisation combined with the use of an ultra-thin magnetic fluid for cooling results in better control, power handling and greatly limits distortion.
The ribbon part of the hybrid module is a magneto-static type tweeter. Four bands of conductive material make up the active diaphragm that is controlled by a strong magnetic field formed around it. The ribbon tweeter is the master of wide dispersion and combining it with the soft dome, you get a tweeter module that can be utilised as low as 2.0 KHz and continues to perform well above 30 KHz. This extreme bandwidth combined with the ultra wide dispersion is an important part of the Dali sonic definition.
Class D Amplifier
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 amplifiers needs and demands.
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 Dali's large woodworking facility in Denmark, they precision-cut the Callisto 6 C MDF cabinets to maintain the high quality, followed by applying the vinyl. The cabinets for the Callisto 6 C are 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 a 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 by themselves. 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.
