Sound Performance & Channel Comparison
Surround Sound Immersion
Q990C's 11.1.4 configuration with detachable rears delivers multi-directional surround; Arc's 3.1.2 is solid but more limited in height and surround placement.
Spatial Audio Codec Support
Q990C supports both Dolby Atmos and DTS:X; Arc only supports Dolby Atmos, limiting compatibility with certain films and streaming content.
Ease of Setup
Arc is plug-and-play via app; Q990C requires placement of multiple speaker units and more complex configuration.
Ecosystem Integration
Sonos Arc integrates seamlessly with Sonos ecosystem for multi-room expansion; Q990C is standalone-focused with limited cross-brand compatibility.
Dialogue Clarity
Both excel at TV dialogue reproduction; neither has a clear advantage in center-channel clarity.
Bass Performance
Q990C's larger subwoofer generally delivers deeper, more authoritative bass; Arc's sub is adequate but more modest in output.
