Description

DALI RUBICON 8

The RUBICON 8 is the largest model in the series. With its three 165 mm woofers, it produces an extremely deep bass with an impressive sound pressure level. What is particularly surprising is how playfully easy the RUBICON 8 converts even the most violent low-frequency impulses. You should have personally experienced this stunning quality in the truest sense of the word to convince yourself how good the speaker sounds.

As an extremely high-quality stereo box, the RUBICON 8 is also suitable for larger living rooms and as the main loudspeaker in larger home cinema systems.

SMC MAGNETIC SYSTEM

An undistorted, coloration-free and detailed music reproduction has always been part of the DALI specifications. With the "Linear Drive Magnet System" consisting of the powdered magnetic material SMC ("Soft Magnetic Compound"), it was possible to significantly improve the sound quality in the upper speaker segment.

Transferring this know-how to cheaper loudspeakers proved to be extremely difficult. The intention to make the best possible use of the positive effect of the SMC material and at the same time not to make the structure of the magnetic drive too complicated led to countless experiments. The result was an SMC pole piece covered with a copper cap and encased in a large ferrite magnet. In this way, the advantage of SMC could be optimally used without the effort and costs increasing too much.

The use of SMC brings many advantages, but above all the distortions in the magnetic drive caused by mechanical losses are reduced considerably. SMC's unique ability to combine high magnetic conductivity with very low electrical conductivity enabled us to develop an excellent speaker drive without the disadvantages that we had previously had to accept. The distortions and thus the discolorations in the sound reproduction could be significantly reduced.

HYBRID TWEETER

DALI's hybrid tweeter module combines a fabric dome with a ribbon tweeter and in this way delivers a transparent, detailed and spatial high-frequency reproduction like no other conventional tweeter technology.

The ribbon is a magnetostatic tweeter. Four bands of conductive material form the active membrane, which is controlled by a powerful magnetic field enclosing it. The transmission range of the ribbon extends from 14 to over 30 kHz. Below that, the dome tweeter, which starts at 2,5 kHz, takes over. The extreme bandwidth and the very even and horizontally wide radiation are important features of the typical DALI sound.

LOW-MIDDLE RANGE

Since the SMC magnetic drive developed by DALI produces almost no disruptive distortions, the other components should also be of a similarly good quality. The extremely light and at the same time extremely stable wood fiber cone membranes with their deliberately uneven surface structure come from the same company that also produces the EPICON membranes. The membrane can move very easily like a piston and possible surface resonances are reduced to a minimum. All in all, these measures ensure very detailed and almost coloration-free music playback, even at low volume.

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.

CASING

Housings made of medium-density fiberboard (MDF) form the solid basis for operating the chassis, which is screwed directly to the 25 mm thick baffle. In order to optimally fix the woofers and integrate them into the housing, the five screws are located exactly in the extensions of the speaker basket. The tweeter module is fixed with four screws to eliminate annoying vibrations and resonances.

Each cabinet provides separate chambers for the mid-bass 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.
