Dali Callisto 2 C Wireless Speakers (without HUB). Available with Online Finance and Free Delivery.
Connect via Bluetooth (AAC/AptX HD) or optional BluOS module (Wi-Fi) to the Dali Sound Hub (See this optional bundle) 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. 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.
Dali Callisto 2 C is the stand mount solution in the new wireless ecosystem that empowers you to easily access all your Hi-Res music directly from your smart device. It 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" 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 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.
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. 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 a driver, the Dali acoustics team were able to elevate audio performance beyond conventional speakers. 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.
Dali used their 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 they were able to 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 a reduction in mechanical distortion and less strain on the amplifier, which leads to more detailing and a better-defined soundstage.
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 an 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 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 form 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.
Class D Amplifier
Designing a ‘best in class’ active speaker system is the sum of many parts. 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 250W for up to 5 seconds, there is plenty of power to ensure ample sound pressure even in complex musical passages or massive explosions in movies.
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 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 in-house assembly lines in Dali's Danish factory.
