Short answer: the Harman Kardon Luna 2. It ranks #23 of 150 medium speakers by sound quality, rated 4.1/5, at $199.95. The DBSONO X-Blast F37 ranks #102, rated 2.8/5, at $69.99, $129.96 cheaper, which does not close the gap in sound quality.
Why pick the Harman Kardon Luna 2: Articulate, spacious midrange with precise imaging and instrument separation. The tradeoff: Treble can sound bright and edgy, and it loses more output off-axis than some rivals.
What the DBSONO X-Blast F37 does well: 25W woofer + 10W tweeter + rear passive radiator. Watch for: Very recessed lower mids, peaky upper mids, just not a great frequency response overall.
Buy the Harman Kardon Luna 2. It is rated higher for sound quality, and saving $129.96 with the DBSONO X-Blast F37 does not make up for the sound-quality gap.

Harman Kardon Luna 2: $199.95 Amazon B&H Photo Video eBay
Older model: the Harman Kardon Luna (ranked lower, rated 4/5).
Pros: Articulate, spacious midrange with precise imaging and instrument separation. Tight, well-controlled bass from the 62mm x 82mm woofer and passive radiator despite the compact body, and it stays cleaner at volume than pricier rivals like the Sonos Play. IP67 rated, and two units pair via AirTouch for true stereo sound.
Cons: Treble can sound bright and edgy, and it loses more output off-axis than some rivals. Some listeners hear mid-range rattling on certain tracks, similar to sibling JBL models. 12-hour battery life trails category leaders like the JBL Charge 6, which doubles it. Single unit is not stereo (1.1 driver layout).
