Multi-room soundbar

A multi-room soundbar is a versatile audio system that combines the functions of a traditional soundbar with the ability to distribute audio throughout the home. It not only serves to significantly improve the sound quality of the television, but also acts as a central audio source for a smart home. Unlike traditional soundbars, which are primarily focused on the home cinema experience, a multi-room soundbar extends the listening experience to all areas of a home equipped with compatible speakers. The multi-room function is at the heart of this technology. It enables audio content to be streamed wirelessly via a home network, usually via Wi-Fi, to various speakers in different rooms. This means that the same music can be played simultaneously in the kitchen and the living room, or that a separate audio source can be played in each room. Control is conveniently handled via an app on a smartphone or tablet. This creates a seamless sound experience that adapts to individual needs and ensures entertainment in every corner of the house.

Core features of a multi-room soundbar

The capabilities of a multi-room soundbar are evident in a range of core functions that significantly influence ease of use and versatility.

Wi-Fi and Bluetooth connectivity

Connectivity is a key feature of multi-room soundbars. The primary connection for the multi-room function is via Wi-Fi. This ensures a stable, high-bandwidth connection, which is necessary for the transmission of high-resolution audio formats without any loss of quality. Wi-Fi also offers greater range and stability than Bluetooth. However, Bluetooth is an important addition, enabling quick and easy connection of mobile devices such as smartphones or tablets directly to the soundbar, allowing music to be played directly from these devices without using the home network. The combination of both technologies offers maximum flexibility for audio playback.

Streaming services and voice control

Modern multi-room soundbars are often directly connected to popular streaming services. This means that music, podcasts or audiobooks from various providers can be played directly via the soundbar without the need for an additional device. Many models also feature built-in voice control. Voice commands can be used to adjust the volume, change tracks or even control other smart home devices, which significantly enhances ease of use. The integration of voice assistants makes the soundbar a central element in the connected home.

Connections and compatibility

The variety of connections is crucial for the flexibility of a multi-room soundbar. Common connections include HDMI with eARC or ARC for the best connection to the TV, optical digital inputs for older TV sets or other audio sources, and sometimes an Ethernet port for a particularly stable network connection. Furthermore, compatibility with various audio standards and multi-room protocols is important. This ensures that the soundbar can communicate seamlessly with other devices in the multi-room system, regardless of the manufacturer. Broad compatibility offers future-proofing and enables flexible expansion of the audio system.

Sound quality and surround sound

Despite the enhanced connectivity, sound quality remains a key criterion for any soundbar.

Subwoofer and sound optimisation

Deep and precise bass is essential for an immersive sound experience. Many multi-room soundbars therefore come with an external subwoofer or offer the option to pair one wirelessly. This ensures powerful bass reproduction that brings action films to life and makes music sound vibrant. In addition, many models feature various sound optimisation modes tailored to specific content. Movie modes emphasise dialogue and effects, whilst music modes aim for balanced reproduction across the entire frequency spectrum. These settings allow for fine-tuning of the sound depending on the application and personal preference.

Surround sound and Dolby technologies

Surround sound reproduction is crucial for a true home cinema experience. Many multi-room soundbars support advanced formats such as Dolby Atmos or DTS:X. These technologies create a three-dimensional soundscape by making sound appear to come not only from the front and sides, but also from above. This creates an impressively immersive sensation that places the listener right at the heart of the action, even without physical ceiling speakers. Some soundbars achieve this by utilising reflections from walls and ceilings or by incorporating up-firing speakers. Support for these technologies is a clear indication of high-quality audio processing and an intense listening experience.

Integration into existing multi-room systems

The ability to integrate seamlessly into an existing multi-room system is a unique selling point of the multi-room soundbar.

Compatibility with established systems

Various manufacturers have established their own multi-room ecosystems, which are renowned for their stability and user-friendliness. These include, for example, systems such as Sonos, Raumfeld or Apple AirPlay. A multi-room soundbar that is compatible with one or more of these systems can be easily integrated into an existing setup. This avoids isolated solutions and enables centralised control of all audio devices via a single app. Compatibility with established systems is a key factor for long-term satisfaction and the expandability of your home audio system.

Expansion options and speakers

The flexibility of a multi-room system lies in its expansion options. A multi-room soundbar is often the starting point for such a system, which can be expanded step by step. Additional wireless speakers can be added in different rooms and synchronised with the soundbar. For example, a stereo pair can be installed in the bedroom, a single speaker in the bathroom and another in the study, all of which can be controlled via the multi-room soundbar. This enables a bespoke audio setup for every room and every situation. The range of compatible speakers is often extensive, so the right size and power output can be found for every room.

Choosing and buying a multi-room soundbar

Finding the right multi-room soundbar requires taking various factors into account.

Before buying, you should consider which features are particularly important. These include the desired sound quality, support for specific surround sound formats such as Dolby Atmos, the integration of streaming services, the type of connections, and compatibility with existing multi-room systems. The size of the soundbar and its design also play a role, as it should fit harmoniously into the living space. Intuitive operation and a user-friendly app interface are also crucial aspects for everyday use.

Installation and setup

Once unpacked, the initial steps are usually completed quickly. The soundbar is connected to the TV via an HDMI cable. For the multi-room function, the soundbar must be integrated into the home network (Wi-Fi). In most cases, this is done via the manufacturer’s own app, which guides you step by step through the setup process. The app detects the soundbar on the network and enables it to connect to the Wi-Fi. You can then add and configure further multi-room speakers via the same app.

The positioning of the soundbar in the room has a significant impact on sound quality. Ideally, the soundbar should be placed centrally below the TV to create a coherent soundstage. It is important that no objects block the sound path. For surround sound effects that rely on reflections, clear side walls and ceilings are advantageous. When integrating a subwoofer, placing it in a corner of the room can enhance the bass, but this should be tested to find the best balance. Careful placement maximises the potential of the multi-room soundbar and ensures an optimal listening experience.
