DALI Callisto 2 C Black Active Bookshelf Speakers (Pair) with 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."

As part of DALI's 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 DALI 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 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.

• Quick setup - Setting up a Hi-Fi system couldn't be easier. You literally only have to connect the power chord to the CALLISTO speakers and the Sound Hub followed by pushing the CONNECT button. And you are ready to stream from your phone or music server.
• 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 2 C woofer benefit from the use of (SMC) Soft Magnetic Compound 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.
• DALI M-600 speaker stands - Offering style and stability these elegant stands will perfectly complement the CALLISTO 2 C stand mount speakers, available to purchase separately.

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 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.

Class D Amplifier

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.

Hybrid Tweeter

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.

6½" Woofer

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.
