Product description

DALI - CALLISTO 2 C - active speaker
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.

Touch Sensitive Volume
The touch sensitive panel atop the CALLISTO speaker cabinet lets you control the volume at the touch of your finger tip. 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.

SMC Technology
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
The low-mass CALLISTO wood fibre cones are optimised to work in perfect balance with the built-in amplifier. This enables the woofers to be more linear than in a similar passive speaker system. This is possible, as we have total control of the entire audio chain.

Class D Amplifier
The CALLISTO 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. It's able to deliver 250 Watts for up to 5 secs, ensuring plenty of power even in complex musical passages or massive movie explosions.

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.

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.

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.

Like its larger sibling, the CALLISTO 2 C features DALI’s innovative hybrid tweeter module, which was optimised specifically for the CALLISTO series. Combining a dome and ribbon tweeter for astonishing rendering of high frequencies, and a dispersion of high frequency audio that outperforms all other tweeter technologies.
The dome membrane is very soft and ultra-lightweight, and actually so thin that a coating has to be applied to hold the material together and be uniform in construction. We have optimised the magnet system to maximize 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, we 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.

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. Only in this way can you achieve an undistorted, uncoloured 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 employ 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 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.
