AMBEO Spatial Audio Technology
The AMBEO Soundbar Plus uses Sennheiser’s AMBEO spatial audio processing technology to simulate a multi-speaker surround system.
Using complex audio processing algorithms, the soundbar creates a wider and more immersive soundstage by directing sound reflections from walls and ceilings. Upward-firing drivers contribute to height effects used in Dolby Atmos content.
This allows the soundbar to simulate surround and overhead audio channels while remaining a single compact unit.
Room Calibration System
The AMBEO Soundbar Plus includes built-in microphones for automatic room calibration.
During setup, the soundbar plays test tones and analyzes how sound reflects within the room. Based on these measurements, it adjusts the sound output to improve spatial accuracy and bass performance.
The calibration process takes only a few minutes and does not require any additional equipment.
Sound Quality
Movie Performance
With Dolby Atmos and DTS:X support, the AMBEO Soundbar Plus creates a cinematic soundstage that enhances action scenes, dialogue clarity, and spatial effects.
The upward-firing speakers help reproduce height channels, creating the sensation of sound coming from above.
Dialogue Clarity
A dedicated voice enhancement feature improves speech intelligibility, making dialogue easier to hear even during complex movie scenes.
Music Playback
The soundbar also performs well for music streaming through services such as Spotify Connect, AirPlay 2, or Chromecast. Stereo tracks can be expanded into a wider soundstage using AMBEO processing.
Optional AMBEO Subwoofer
While the soundbar includes two built-in subwoofers, Sennheiser also offers the optional AMBEO Sub for deeper low-frequency performance.
The wireless subwoofer uses an 8-inch driver and powerful amplification to deliver stronger bass response, especially in larger living rooms or home theatre setups.
Multiple subwoofers can be connected for even greater bass impact.
