Sound Hub is the core of DALI wireless Hi-Fi audio system, from CALLISTO to RUBICON C series, it dominates the connection transmission of the entire system. In principle, whether it is an analog or digital input signal, it is transmitted by the Sound Hub to the speaker wirelessly. The actual difference between Hi-Fi speakers and ordinary speakers is that the former reproduces sounds highly similar to the original ones. For Hi-Fi companies pursuing sound quality, the production of wireless Hi-Fi audio systems requires a certain strength foundation.

DALI's wireless transmission technology is re-developed based on today's mature transmission technology. It can transmit uncompressed 24bit/96kHz high-definition audio signals to speakers. In terms of wireless Bluetooth connection, it supports apt-X HD and the AAC format dedicated to Apple devices, and can also play MQA files. These conditions can already meet the basic needs of audiophiles. From removing the speaker to using the Sound Hub to connect to the phone's Bluetooth, the entire process took me less than 20 minutes.

RUBICON 6 C uses the design of a hybrid tweeter module, that is, it has an aluminum ribbon tweeter and a silk dome tweeter. Due to the use of metal diaphragm made of aluminum, the ribbon tweeter has the characteristics of fast transient speed and wide high frequency limit. Together with the operation of the silk dome tweeter, RUBICON 6 C can operate smoothly at a frequency of up to 30kHz . We can hear more sound details on RUBICON 6 C. The unique double tweeter design makes the sound quality played back more delicate and smooth.

RUBICON 6 C's mid-bass unit is the first to attract attention, because it uses wood fiber paper cones, and even the texture is similar to wood veneer. The acoustic design behind is also worth studying, it uses DALI's patented technology-linear drive magnetic circuit system. This technology mainly uses a soft magnetic compound (SMC) as the material, which is of great significance to the operation of the woofer magnetic circuit system. SMC can bring higher magnetic permeability and lower electrical conductivity. Greatly reduce the sound pollution, make up for the distortion of sound effects caused by mechanical loss.

There is a single inverted hole design behind the two woofers. The designer also specially optimized the time synchronization between the woofer and the inverted hole. This can provide more sufficient low-frequency volume sense and eliminate the box. The problem of sound pollution when the body resonates. RUBICON 6 C has a built-in 250W Class D digital amplifier. The bass and tweeter units are driven by separate power amplifiers. DALI also intentionally replaces the original analog crossover with a digital crossover.

RUBICON 6 C

The RUBICON 6 C with Bluetooth connection has a strong digital flavor, the tri-band performance is balanced, especially the vocal part is outstanding, and the high-resolution reproduction does not appear distorted even at a large sound pressure. The experience of using it to listen to popular music is also excellent. Although using Bluetooth to play it does not appear to be much missing, but it seems to lack a certain charm.

After using the CD player, the symphony instantly highlighted the outstanding resolution of the speakers. In the music of the fifth segment of "Four Seasons", I clearly heard the slight vibrato behind the violin solo. The contrast is not very strong, but the sound of the instrument is generally heard. It is natural and refreshing. The openness of RUBICON 6 C is very strong. Walking around in the spacious audio-visual room can also be infected by a wide range of sound places.
