REMEMBER YESTERDAY. ENJOY TODAY. EMBRACE TOMORROW. Investing in the newest tech is, for some enthusiasts, the essence of Hi-Fi. Others want to invest once and keep their audio system for decades. Either way, this goes along with the joy of listening to their favourite songs and the urge to explore new music. There are multiple sources to gain these great sound experiences from .
DALI RUBICON C ACTIVE SPEAKERS Bringing the DALI RUBICON into the world of active speakers was both a logical step and a daunting task. The RUBICON range has over the years since its launch gained abundant praise for its superior audio performance.
DALI SOUND HUB – wireless audio The DALI SOUND HUB is the starting point when setting up RUBICON C speakers. It is the distribution source of the wireless audio signal and where the pairing process begins. The DALI SOUND HUB houses all the potential connections; has built-in controls for Power On/Off, Volume control, Source select, Mute and Speaker pairing, and also visual indications for Volume, Source and Speaker placement.
The wireless CALLISTO system is MQA Certified by MQA Ltd. This applies to the DALI products using the sound hub installed with the optional BluOS NPM-1 plug-in module. EXPANSION PORTS – Future-proofing your RUBICON C speakers The key to expansion and having a long lasting audio system are the expansion ports. The two modular expansion ports on the back panel form one of the most innovative features of the DALI SOUND HUB, and opens a world of possibilities.
CABINET Made from Medium Density Fibre board (MDF), the RUBICON C series cabinets form a rigid foundation for the drivers, which are screw-mounted directly into the 25 mm thick front baffle. The woofers are secured to the cabinet using five screws, each positioned on the arms of the die-cast aluminium chassis, ensuring the most secure mounting possible. The hybrid tweeter module is molded in thick, solid aluminium and held securely in place with four screws to eliminate vibrations and resonance.
THE AMPLIFIER Designing a ‘best in class’ active speaker system is the combination of many elements. One truly important element is the amplifier, or more correctly, the amplifier module. Using a digital crossover in place of the RUBICON’s analogue one, the two amplifiers in each speaker drive the woofers and tweeters directly. This enables our acoustic engineers to optimise the interaction between amplifier and driver perfectly, bringing out even more detail from the source material than possible before.
Signal processing The core of the signal processing is comprised of a 50MIPS Digital Signal Processor, and an audiophile 24bit Digital to Analogue Converter. The DSP boasts an audio processor capable of up to 1024 instructions per cycle. On the output side, the DSP is connected through I2S to a Burr Brown DAC that makes use of advanced segment architecture to achieve excellent 123dB dynamic range performance.
WOOFER Having designed a magnet motor system that introduces almost no distortion, we wanted to add components that had these same qualities. We designed a woofer (bass/midrange driver) which is able to reach up well into the upper midrange making the “handover” from the woofer to the tweeter sound entirely seamless. Using a 6½” wood fibre cone manufactured by the same company that makes the EPICON cones, gives the woofer a light, rigid and randomly uneven membrane.
Low Loss Magnetism The use of SMC (Soft Magnetic Compound) has many advantages, but the overarching result is a significant reduction of distortion from losses in the magnet motor. SMC’s unique ability to deliver a high magnetic conductivity and a very low electrical conductivity, gives us all the desired qualities of a really good speaker magnet, without the traditional disadvantages.
Inductance Linearization Making our speakers amplifier-friendly is an important part of the design process. We want to make sure that it is the amplifier and not the speaker that forms the audio signal. To get the best from the amplifier, the speaker has to deliver a stable working environment. By keeping the impedance as flat as possible across the entire frequency range, the amplifier is able to deliver the same amount of power at all frequencies.
TWEETER The tweeter modules are driven directly from the 250-Watt amplifier leaving the crossover function to the DSP. On the RUBICON 2 C, the high frequencies are handled by a soft dome tweeter and on RUBICON 6 C, a hybrid tweeter module. The hybrid tweeter module is one of DALI’s trademarks. It combines a dome tweeter with a ribbon tweeter for an amazing reproduction of high frequencies, with wide dispersion at ultra-high frequencies keeping things crisp and airy.
OUTRO The RUBICON C series represents a new era of revolution in loudspeaker development, yet still delivers on DALI’s entire core values in a wireless context. With its own character, this elegant audio system delivers modern Hi-Fi with the same high level of quality, and in some ways better than the original RUBICON series. In high-tech dialogue with the DALI SOUND HUB, the RUBICON C delivers solid and trustworthy high performance audio.
