These are not really the same size class, and that is the honest framing here. The Harman Kardon Citation 200 ranks #13 of 78 large speakers by sound quality at $130; the Sonos Roam 2 ranks #74 of 142 medium speakers by sound quality at $179.
The case for the Harman Kardon Citation 200: Deeper bass than any Onyx. The tradeoff: Overly boomy by default, you can short press the Bluetooth and volume down buttons simultaneously to decrease the bass, and the Bluetooth and volume up buttons simultaneously to increase it.
The case for the Sonos Roam 2: Very neutral. The tradeoff: Exact same sound quality as the original Roam.
Buy the Harman Kardon Citation 200 ($130) for a large speaker; the Sonos Roam 2 ($179) suits a medium speaker instead.
