The S10-based speaker has improved computational audio, colorful Sound Glow lighting and the ability to work as a default speaker on compatible newer Macs. Four-speaker surround requires a new Apple TV and supported matching speaker pairs; it is not an open-ended mix with Sonos. These details matter more than the new colors.
Action: price one mini as a desktop speaker separately from the much larger cost of a four-speaker theater. Read the compatibility footnotes before preordering.
