DALI Callisto 6 C Black Active Floorstanding Speakers (Pair) w/ Sound Hub / BluOS Module

Full Description

Best Product 2018-2019 - Wireless System

"One of the major downsides of having a decent hi-fi system in your home is the mess of cables that inevitably results. DALI has overcome this by producing the active Callisto loudspeakers that work with the company’s Sound Hub. Stable transmission at a high 96kHz/24-bit resolution gives great stereo sound without wires."

The 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 sound stage into even large rooms, while adding extra width and depth. The two woofers and large internal cabinet volume ensures truly deep bass performance and room filling sound-pressure levels. All this without the need of complicated electronics.

CALLISTO 6 C represents the virtues of traditional Hi-Fi wrapped in a convenient wireless audio solution. DALI have developed everything from the CALLISTO 6 C drivers to the amplifier 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. 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.

The DALI Sound Hub features an extended range of digital and analogue inputs combined with an auto source sensing system. The Sound Hub automatically activates the right input the moment you start playing music or turn on your TV, so you can just sit back and enjoy exquisite audio. The front-facing volume knob embeds an LED display, which combines Hi-Fi tradition with convenience. The LED display shows the current audio source as well as the volume level, and you can even adjust the light intensity of the display. This is supported by a light display on top of the Sound Hub, which indicates the location of the CALLISTO speakers in the pairing process.

• 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.
• 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.
• 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.

Sound Hub

DALI have made the setup simple, so you only have to worry about adjusting the volume, which can be done via a multitude of options. E.g. on the Sound Hub, by using the included Bluetooth remote, directly via the touch panels built atop of each speaker or via your smart device (depends on the brand).The Sound Hub supports a list of different sources: Bluetooth (AAC & Apt-X HD), Analogue (RCA & Mini Jack), Coaxial RCA, 2 x Optical (Audio & TV), USB output (Google Chromecast Audio).

BluOS Module

Access almost any streaming service via the free BluOS app. BluOS wirelessly transmits music up to 24-bit/192kHz at a high rate without lag and loss in sound quality. Via Wi-Fi or Bluetooth, you can access and share music from a computer, phone, tablet or network-attached storage drive (NAS) or you can use your all-access pass to an enormous library of music available in the many music streaming libraries and internet radio apps, which are built right into the BluOS NPM-1 module.

Precision Cut Cabinets

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 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.

Class D Amplifier

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.

Hybrid Tweeter

The 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 high frequency audio that outperforms all other tweeter technologies.

Two 6½" Woofers

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 driver, the DALI acoustics team were able to elevate audio performance beyond conventional speakers.
