Dolby Atmos adds height channels to a conventional surround system, allowing soundtracks to reproduce effects above the listening area as part of a three-dimensional sound field. The right speaker solution depends on your existing system, room layout, ceiling and intended channel configuration.
Atmos modules or integrated Atmos speakers
Dedicated Atmos modules can be added to compatible front or surround speakers, making them a practical way to expand an existing home cinema system.
Some floorstanding speakers integrate an additional upward-firing Atmos channel into the cabinet. This provides a cleaner all-in-one installation while retaining separate connections and amplification for the height channel.
Upward-firing sound
Upward-firing Atmos speakers direct sound towards the ceiling so that reflected energy reaches the listening area from above. Their performance therefore depends partly on the room and ceiling.
Ceiling height, shape and surface can influence the effectiveness of this approach. A relatively flat, reflective ceiling generally provides more predictable results than a very high, sloped or strongly absorptive ceiling.
AV receiver and amplification
Adding Atmos channels requires an AV receiver or processor capable of decoding Dolby Atmos and supporting the intended number of channels.
Remember that integrated Atmos floorstanding speakers still require separate amplification channels for their height drivers. The Atmos section is not simply powered internally by the main speaker connection.
System configuration
The number of Atmos speakers depends on the intended layout and the capabilities of the AV receiver or processor. Common configurations can use two or four height channels in addition to the conventional ear-level speakers.
For best results, speaker position and channel assignment should be planned as part of the complete system.
Finding the right solution
Start with your existing speaker system, room size and AV electronics. Dedicated Atmos modules are particularly useful when upgrading an existing system, while floorstanding speakers with integrated Atmos channels provide an elegant solution when building or replacing the complete front speaker system.
