The rise of electric vehicles is not just about clean energy—it’s also transforming the in-cabin experience. Without the constant hum of combustion engines, sound has become the new battleground. The Huawei Sound Ultimate system, debuting in the Maextro S800 luxury sedan, demonstrates how advanced acoustics can turn an EV into a rolling concert hall.
Huawei’s Journey Into Automotive Audio
Huawei has invested in audio technology since 2012, combining decades of consumer electronics expertise with innovative acoustic engineering. The result is the Huawei Sound Ultimate Series, designed to reproduce music exactly as artists intended. According to Lars Goller, Huawei’s Chief Automotive Sound and Acoustics Advisor, the goal is to create “the outstanding phantom effect of sitting right where the music was created.”
The Maextro S800 is the first car to feature this ambitious system, signaling a new chapter for Chinese-developed high-end sound technology.
Key Features of Huawei Sound Ultimate
The system transforms the Maextro S800 into a symphony on wheels with:
- 43 speakers strategically placed for an ultra-immersive surround experience
- Dual amplifiers producing 2,920 Watts of power
- 4D exciters in rear seats, vibrating in sync with music and video content
- Crystal Star-Ring Diffuser, a dashboard centerpiece that rises when doors open, paired with ambient lighting that pulses with music
- Tangential Force Woofer, a 90-degree rotated woofer that minimizes vibration for cleaner bass
- Dual-Diaphragm Subwoofer, using cabin space for layered, powerful low frequencies
Independent Sound Zones and Spatial Audio
A world-first innovation in the Huawei Sound Ultimate system is independent sound zone technology. Using advanced field control algorithms, the system achieves up to 30 dB isolation between front and rear seats. This allows passengers to enjoy separate audio sources without interference.
In addition, 10 overhead channels and Huawei’s spatial audio track model ensure sound positioning is incredibly precise, creating a true 3D listening environment.
AI-Powered Sound-to-Light Technology
The Maextro S800 also integrates AI-driven sound-to-light features. Interior ambient lighting synchronizes with the rhythm and mood of music, transforming audio into a visual experience. This harmony between sound and light deepens the emotional atmosphere inside the cabin.
All of this runs on a HarmonyOS-based ecosystem, ensuring seamless connectivity and control.
Conclusion
With the Huawei Sound Ultimate system, the Maextro S800 is redefining what in-car audio can achieve. From independent sound zones to AI-powered lighting, the experience goes far beyond playback. Huawei’s push into automotive acoustics signals not only competition with established global brands but also the beginning of a new era where electric luxury cars double as immersive entertainment spaces.
