Description

DALI RUBICON 6 C

The RUBICON 6 C is part of an active loudspeaker system that is unique in this class with a powerful driver constellation that combines musically homogeneous reproduction with a powerful, very deep bass. The floorstanding loudspeaker is controlled via the extremely stable wireless radio connection of its own proprietary network. Two 250 watt Class D amplifiers provide each RUBICON 6 C speaker with enough power to ensure more than enough sound pressure even with complex music passages or massive movie explosions.

AMPLIFIER

The development of a high-quality active speaker system involves many aspects. A really important part is the amplifier, more precisely: the amplifier module.

Instead of using an analogue crossover as in the passive RUBICON 6, the individual chassis of the active RUBICON 6 C are driven directly via a digital sound processor and the two amplifiers integrated in each loudspeaker. In this way, the developers can optimally match the DSP, amplifier and driver to one another and achieve particularly detailed reproduction.

One of the two 165 watt amplifiers is reserved for the two 250 mm wood fiber woofers. The combination of a particularly low-loss design, wood fiber cone and SMC pole piece makes it possible for these woofers to have minimal distortion. Together with the particularly musically designed Class D amplifier, an extremely detailed and dynamic reproduction is guaranteed.

The Class D amplifiers are based on the latest patented technologies, are self-oscillating and work with global negative feedback, which is used due to their musical design. In order to adequately reproduce complex music passages or violent explosions in feature films, 250 watts of power are available for pulses of up to five seconds.

SPEAKER CHASSIS

WOOFER
The cone is encased in a soft, low-loss rubber surround, designed from the ground up and custom-made for the RUBICON drivers. The bead guarantees that the membrane can move easily and without loss of energy.

All components are fixed in an aluminum basket that allows maximum air movement around the cone and magnet system. The use of an electrically non-conductive aluminum basket again ensures that the magnetic field around the magnetic drive is not affected.

HYBRID TWEETER
The hybrid tweeter module, which has long since become a DALI trademark, combines a dome tweeter with a ribbon tweeter and thus offers resolution and radiation characteristics superior to all other tweeters.

The extremely soft and light dome membrane is so thin that a coating has to reinforce the material and ensure an even surface. The magnet system was further improved by computer simulation and the saturation flux density in the area of ​​the voice coil was maximized. As a result of this and the use of an extremely low-viscosity magnetic fluid for cooling, the tweeter has a very linear force factor throughout the deflection and thus more controlled movement, higher resilience and lower distortion.

The second part of the hybrid module, the ribbon, is a magnetostatic tweeter. Four bands of conductive material form the active membrane, which is driven by a strong magnetic field surrounding it. Ribbon tweeters have a very wide radiation pattern and in combination with the dome, the module covers the frequency range from 2 to 30 kHz. This extreme bandwidth, together with the wide dispersion, represents an important part of the DALI sound philosophy

CASING

The housing of the RUBICON 6 C offers separate chambers for the bass-midrange and woofers. This allows the housing volume to be optimized precisely for the respective chassis and the frequency range it transmits. In addition, there is an individual bass reflex opening directly behind each woofer, which reduces turbulence to a minimum and optimizes the transit times between the woofer and the reflex opening. Several internal braces also prevent unwanted cabinet resonances and sound coloration.
