Dali Oberon 7 C HC 5.1: the ultimate wireless home theater speaker pack


Mis à jour le 13 May 2022.

The Dali Oberon 7 C HC 5.1 speaker pack relies on the Dali Equi ecosystem to create a scalable wireless home theater system. It relies on the power of the 24-bit/96kHz wireless transmission of the Dali Sound Hub , to which is added the Multichannel HDMI 7.1/5.1 module with HDMI eARC input to play Dolby or DTS soundtracks from the television. Retailing for €4490, this set promises to take wireless home theater systems to new heights.

The Dali Oberon 7 C HC 5.1 speaker pack allows you to build a real 5.1-channel home theater system without cables and without amplifier.

Dali Oberon 7 C HC 5.1: packaging & accessories

Each speaker in the Dali Oberon 7 C HC 5.1 wireless home theater system comes with a magnetic acoustic cover and a mains power cable. It also comes with a quick installation guide and rubber pads. The essential Dali Sound Hub preamp comes in a separate box including a quick start guide, a 1.7m long power cable and an infrared remote control. We received it accompanied by the HDMI Dali module, also delivered in its own box. Finally, a USB flashdrive accompanies the set in order to carry out the update which is essential to the proper functioning of the system.

Dali Equi: wireless home theater system

The Danish manufacturer has become a master of its craft when it comes wireless speakers with the launch of the revolutionary Dali Calisto C range in 2017. The brand then continued innovating with the Equi technology and the Dali Oberon C range which consists of the Dali Oberon On Wall C , Dali Oberon 7C , Dali Oberon 1C and Dali Oberon Vokal C. For the upper Dali Rubicon C range, the wireless system includes the Dali Rubicon 2 C , Dali Rubicon 6 C and Dali Rubicon 8C loudspeakers. These active wireless speakers are directly declined from their passive counterparts in which are added a specifically calibrated amplification and a module in charge of wireless transmission. A design that allows you to enjoy true wireless hi-fi speakers and which has earned the brand praise from the international press. In particular the EISA prize which highlights “high quality musical performance thanks to the best loudspeaker technology developped by DALI”.

All speakers from the Dali Oberon C and Dali Rubicon C ranges can be used to create a wireless home theater system. To set up a wireless home theater system, the Dali Sound Hub pre-amp is essential. It groups the different sources, pre-amplies them and broadcast the signal wirelessly in 24-bit/96kHz to the connected Dali speakers. It then becomes possible to create a scalable system ranging from 2 to 7.1 channels. However, we wish there were Atmos speakers in this wireless system. Something that the Danish manufacturer could easily add later.

The Dali Sound Hub transmitter and preamp can stream the sound of a TV to a Dali speaker system up to 7.1 channels.

The Dali Sound Hub pre-amp is equipped with two analog inputs (a stereo RCA input and a 3.5mm mini-jack input) and three digital inputs (2 optical inputs and a coaxial input). It also has two bays on its back panel to mount additional modules. The first is the Dali NPM-2i BluOS , a all-rounder of a network player that we used in our review ot the Dali Rubicon 2C. The second is the new Dali HDMI 7.1/5.1 module which adds an HDMI eARC input, as well as a Dolby and DTS multi-channel decoder. This module is therefore essential for using Dali wireless speakers in a multi-channel configuration.

Thanks to the HDMI eARC module, the Dali Sound Hub preamp can retrieve and broadcast the soundtrack of the program viewed on the television.

In terms of design, the Dali Sound Hub preamp adopts a control interface on its front panel consisting of a power button, a mute button and a source selector. The front of the device also features a large volume knob with a backlit screen to control the sound level. It also displays the general volume and the source currently playing. On its top panel, the Dali player features a lacquered surface on which a screen displays the configuration of the speakers installed. Using the Dali Sound Hub, you can also adjust the level of each speaker in the system. To do so, it is necessary to simultaneously press the mute and source selection buttons. The first speaker then emits a beeping sound. You can then easily turn its volume up or down depending on its position in the room. Once you find the setting that works the best for you, you can move on to the next speaker.

The volume knob of the Dali Sound Hub has a screen in its center. It displays the listening level and the source currently playing.

Finally, the Dali Sound Hub can be controlled remotely using its infrared remote control. This allows you to adjust the volume, select the source and turn on the pre-amp. Thanks to the Dali HDMI module, the Dali Sound Hub can also be controlled from the associated TV remote control.

The Dali Oberon 7 C HC 5.1 system can be easily controlled from the Dali Sound Hub remote control or from that of the associated television.

Dali Oberon 7 C HC 5.1: presentation

The Dali Sound Hub preamp, decoder and transmitter makes it possible to create a wireless home theater system with speakers from the Dali Rubicon C and Dali Oberon C ranges. For this review, we opted for the Dali Equi Oberon 7C HC 5.1 system. In addition to the pre-amp and the HDMI module, this system consists of a pair of Dali Oberon 7 C floorstanding speakers, a pair of Dali Oberon 1 C bookshelf speakers used here for the surround effects and the central speaker Dali Oberon Vokal C. We also used the Dali Sub C8-D subwoofer. This model is however the only wired element of the pack and needs to be connected to the subwoofer output of the Dali Sound Hub. For greater freedom of placement, this subwoofer can be transformed into a wireless model using the Dali Dongle Wireless Subwoofer module.

All the speakers of the Dali Oberon 7 C HC 5.1 wireless home cinema use the acoustic design of their passive counterparts, namely the Dali Oberon 7 , Dali Oberon 1 and Dali Oberon Vokal . We find in particular the 1.14″ textile dome tweeter common to the entire range. This tweeter is a bit larger than traditional models and provides a wider dispersion zone, for better perception of the different frequencies, even when the listener isn’t in the optimal listening axis. The distortion level is also reduces and power handling improved. Finally, this tweeter is capable of operating up to 26kHz on all Dali Oberon C loudspeakers, guaranteeing better perception of the various harmonics.

The 1.14″ tweeter fitted on all Dali Oberon C connected speakers allows a wider sound distribution for better treble perception.

All the wireless speakers in the Dali Oberon 7 C HC 5.1 pack also benefit from a midrange/bass driver made by Dali. Although the diameter differs according to the speakers (1 x 5″ for the Dali Oberon 1 C, 2 x 5″ for the Dali Oberon Vokal C and 2 x 6.7″ for the Dali Oberon 7C), all the drivers are based on the same design. All feature a cone made of wood fibers to maximize rigidity and guarantee optimal operation of the drivers. The magnetic system uses proprietary SMC (Soft Magnetic Compound) technology. This makes it possible to significantly reduce the distortion of the audio signal in the voice coil. To do this, the loudspeaker magnet uses a composite magnetic compound, infinitely less conductive than most of the alloys usually used (ferrite or neodymium, for example). The voice coil is also enclosed in a copper cap to reduce its inductance and incidentally the distortion/harshness of the high-mid and treble registers. All speakers use a bass-reflex enclosure for better bass reproduction.

Thanks to SMC technology, the mid/bass drivers of the Dali Oberon C loudspeakers offer precise and detailed reproduction.

Each connected speaker of the Dali Oberon 7 C HC 5.1 wireless home theater system features two amplifiers, for a power of 2 x 50W RMS. The first module powers the tweeter, while the second drives the two midrange/bass speakers. These are class D models, which ensures a very good impulse response. This set can thus accumulate a total power of 500W RMS with the speakers and 670W RMS when adding the subwoofer. Furthermore, the use of dedicated amplifiers allows each loudspeaker to operate independently, without depending on the power allocated to the other loudspeakers as is the case with conventional loudspeakers connected to an AV receiver.

Each speaker in the Dali Oberon 7 C HC 5.1 pack includes its own power supply and 2 x 50 watt amplification.

The Dali Sub C8-D subwoofer is equipped with a large 8″ driver to produce deeper and more powerful lows. Its cone is also made of paper pulp to maximize rigidity and ensure excellent responsiveness thanks in particular to its lightness. The driver’s magnetic system is designed around an oversized ferrite magnet and optimized to promote maximum flux within the voice coil. This 1″ coil allows significant movement to increase bass level. This long throw is also due to an imposing surround which ensures greater movement, but also more linearity for a better reproduction of transients. This driver is powered by an amplifier rated at 170 W RMS (220 W peak) and can reproduce frequencies down to 33Hz. It should thus do very well with home theater use as well but also to listen to music.

With a 8″ driver and a 170 W RMS amplifier, the Dali Sub C8-D subwoofer delivers powerful, deep lows down to 33Hz.

In terms of design, the various loudspeakers in the Dali Oberon 7 C HC 5.1 pack identically reproduce the understated and elegant lines of the original versions. The cabinets are made of MDF and use internal braces to limit vibrations. The Dali Oberon 7C are beautiful floorstanders with their aluminum base which gives the impression that the speaker is floating in the air. The Dali Oberon 1C are relatively compact (16cm wide by 27cm high and 23 deep), allowing them to be easily installed on a shelf, on a piece of furniture or on dedicated stands. It is also possible to mount them on the wall thanks to the integrated support. Finally, the Dali Oberon Vokal C center speaker is also quite compact (44 cm long, 16 high and 29 cm deep), allowing it to be easily installed in front of the TV or in the niche of a piece of furniture.

With its compact dimensions, the central Dali Oberon Vokal C can be placed in front of a TV or in the niche of a TV stand.

Dali Oberon 7 C HC 5.1: testing conditions

While setting up Dali wireless speakers for stereo use has always been quick and easy, home theater setup is a bit more complex. With Dali speakers purchased or produced before the end of 2021, it will be necessary to update the firmware of each speaker to use them in a home theater system. As the Dali Oberon 7C system is devoid of network connection and mobile application, the procedure is carried out from a computer by downloading the Dali Upgrade Tool software for Mac and Windows from the Dali website. From there, you can install the latest version of the firmware for each speaker on a USB key. This is included with the center speaker. If you prefer to use your own flashdrive, it must have a storage space ranging from 512 MB to 32 GB. Note. All the data present on the flashdrive will be erased beforehand. Once the operation is complete, eject and remove the flashdrive from the PC/Mac.

Depending on the speaker version, it may be necessary to update the firmware using the Dali Upgrade Tool software for Windows and Mac.

To update a Dali speaker, unplug the mains power cable, then insert the USB key into the service port. Then turn the speaker back on. Power LED lights red/orange for about 1 second, then turns off again. Wait up to 20 seconds for the upgrade to complete. When the light flashes green, the upgrade is complete. Remove the USB drive and the speaker will reboot and be ready to use. This procedure must be carried out for each loudspeaker in the system, but also for the Dali Sound Hub. Without being complex, it still requires time (about 10 to 15 minutes) and patience. We are far from the simple installation process advertised by the manufacturer. Fortunately, the latest Dali productions are directly updated at the factory.

After configuring the Dali USB flashdrive, simply insert it into the dedicated port of each speaker to update the firmware.

Once all the speakers have been updated, the HDMI module can be installed in the Dali Sound Hub pre-amp. Installing it is very easy. To do this, simply remove the protection placed in front of the dedicated rack, then insert the card. Note however that it is necessary to bring a Torx screwdriver to remove the cover.

Installing the HDMI module is quick and easy using a Torx screwdriver (not included).

Then, you can power up the Dali Sound Hub to make the pairings. To do this, first press the “Link & Connect” button on the Dali Sound Hub, then that of the speaker to be associated. Once detected, it emits a sound and allows you to define the channel to reproduce by pressing the “Link & Connect” button several times to define its role. A light located on the back of the speaker then indicates its placement in the room. Repeat these two steps on each speaker in the system. Finally, press the Dali Sound Hub pairing control one last time to finalize the procedure. If necessary, the sound level of each loudspeaker can be independently adjusted to compensate for its placement in the room.

Using the button located on the back of each speaker of the Dali Oberon 7 C HC 5.1 home cinema pack, pairing can be carried out and the channel to be played can be easily selected.

For this test, we also used the Dali Dongle Wireless Subwoofer to wirelessly link the subwoofer. This small receiver comes with a subwoofer cable to connect it to the subwoofer and a USB-C to USB-A cable for power. This cable can be connected to the TV’s USB port or to a USB mains adapter (not included). The pairing procedure is then identical to that of the speakers.

The Dali Dongle Wireless Subwoofer module allows any subwoofer to be wirelessly connected to the Dali Sound Hub.

Once the different speakers are associated, all that remains is to connect the TV via HDMI eARC so that the system is finally operational. As no HDMI cable is included with the HDMI module, it is necessary to have a quality cable such as the Norstone Arran HDMI to ensure an optimal connection. Then, you can set the Convenience or Performance mode from the HDMI module. The latter can reproduce the full dynamic range of soundtracks and films. The first can be compared to a night mode, with dynamic compression to reduce large volume differences. This function is ideal for enjoying night sessions without disturbing the rest of the family or neighbors. A dedicated command on the remote control would have been more user-friendly than a selector on the back of the hub. More extensive DSP modes like those offered by traditional home theater receivers would have been a nice touch too.

The HDMI module of the Dali Sound Hub incorporates a selector for activating a night mode to achieve dynamic compression and limit volume differences.
