Short answer: the Harman Kardon Citation 200. It ranks #13 of 77 large speakers by sound quality at $130; the Marshall Kilburn II ranks #36 and costs $279, so there is little reason to consider the other one.
What the Harman Kardon Citation 200 offers: Deeper bass than any Onyx. Watch for: 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
What the Marshall Kilburn II offers: 20W Class D amp + dual 8W tweeters. 20+ hour battery with quick-charge (20 min charges 3 hours of play). Rugged design with leather handle and reinforced corners, IPX2 rated. Thrives with rock music. Bluetooth 5.0 with 30ft range. Watch for: Boosted upper bass, not very detailed, not as deep bass as competitors, upper mids peak. Very low IPX2 water rating. AC charging
Buy the Harman Kardon Citation 200. It ranks higher for sound quality than the Marshall Kilburn II and costs less, so there is no real case for the other one.
