Sonos Arc vs Bose 900 Detailed Feature Comparison
Audio Channels and Drivers
Sonos Arc employs a 5.0.2 configuration with eleven custom drivers powered by eleven Class-D digital amplifiers, including eight elliptical woofers, three tweeters, and upward-firing height channels for immersive Dolby Atmos effects. Bose Smart Soundbar 900 uses a similar 5.0.2 setup but with nine full-range transducers, four cone woofers, and one dome tweeter, relying on PhaseGuide technology for multi-directional sound without side-firing drivers. The Arc delivers more precise height and width, creating a wider soundstage, while Bose emphasizes expansive breadth but falls short in overhead immersion compared to Arc’s dedicated drivers.
Room Calibration
Sonos Arc features Trueplay tuning, which uses an iOS device’s microphone to analyze room acoustics and optimize sound via app-based adjustments, ensuring tailored performance across spaces. Bose 900 employs ADAPTiQ, a headset-based calibration system that measures room reflections for precise audio mapping, offering superior setup accuracy without needing a phone. Trueplay suits Apple users seamlessly, but Bose’s method provides more comprehensive environmental adaptation, though it requires wearing a microphone headband.
Connectivity Options
Both support HDMI eARC for lossless audio, Wi-Fi, Apple AirPlay 2, and Spotify Connect, with optical inputs available. Sonos Arc adds DTS support and Ethernet but lacks Bluetooth, prioritizing ecosystem integration. Bose 900 includes Bluetooth 4.2, Google Cast, and Voice4Video for enhanced TV control via Alexa, providing broader wireless playback versatility. Arc excels in multi-room Sonos expansion, while Bose offers more standalone streaming flexibility.
Dialogue Enhancement
Sonos Arc’s Speech Enhancement, tuned by Oscar-winning engineers, clarifies whispers and intense scenes via app activation, ensuring dialogue cuts through effects without distortion. Bose 900 uses Dialogue Enhancement and TrueSpace for virtual surround, boosting vocal presence effectively in spacious rooms. Arc provides more natural, detailed clarity for movies, outperforming Bose’s processed sound in complex audio mixes.
Design and Dimensions
Sonos Arc measures 114.2 x 8.7 x 11.6 cm and weighs 6.25 kg, with a curved grille suited for larger TVs, touch controls, and no remote. Bose 900 is slimmer at 104.5 x 5.8 x 10.8 cm and 5.75 kg, featuring a premium tempered glass top, rounded edges, and an included remote for easier access. Arc prioritises immersive scale, while Bose fits compact setups better with its lower profile.

Bose Smart Soundbar 900 Likes and Dislikes
The Bose Smart Soundbar 900, available on Amazon.in, earns praise for its expansive sound breadth, sleek tempered glass design, and clear vocal projection via Dialogue Enhancement and TrueSpace processing, making it ideal for cinematic experiences in spacious rooms. Users appreciate the ADAPTiQ room calibration for precise audio tuning, Bluetooth 4.2 connectivity, Google Cast, and included remote for easy control, plus strong multi-directional sound from PhaseGuide technology despite fewer drivers.
However, dislikes include noticeably processed audio lacking naturalness, weaker Dolby Atmos height effects compared to rivals, no DTS support, and limited soundstage extension without side-firing drivers. Bass feels decent standalone but lacks depth at high volumes, and music playback can sound overly bright or aggressive in rock genres, with sensitivity to source quality reducing consistency.
Sonos Arc Likes and Dislikes
The Sonos Arc, listed on Amazon.in, stands out for its immersive 5.0.2 Dolby Atmos performance with 11 drivers, delivering spacious, weighty soundstages, potent bass, and precise height effects from upward- and side-firing speakers, excelling in movies and Atmos music. Trueplay tuning optimizes for rooms via iOS, Speech Enhancement clarifies dialogue naturally, and seamless Sonos multi-room integration with Ethernet enhances expandability. Critics note minor lacks like no Bluetooth, absence of a physical remote, slight music directness issues, and iOS-only Trueplay limiting Android users. No center channel adjustment and occasional muddiness in dense mixes are drawbacks, though software updates improve height control.
