These are not really the same size class, and that is the honest framing here. The Harman Kardon Luna 2 ranks #22 of 138 medium speakers by sound quality at $199.95; the Marshall Stockwell 2 ranks #11 of 77 large speakers by sound quality at $200.
The case for the Harman Kardon Luna 2: 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. Watch for: 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.
What the Marshall Stockwell 2 offers: Possibly the most natural sounding Marshall speaker. Excellent off-axis. The tradeoff: Not stereo. Not very loud. Uses added DSP reverb which audio purists may find annoying.
Buy the Harman Kardon Luna 2 at $199.95 for a medium speaker, or the Marshall Stockwell 2 at $200 for a large speaker instead.
There is a real battery-life gap here: the Marshall Stockwell 2 is rated for 20 hours, the Harman Kardon Luna 2 only 12 hours.
Water resistance is not close: the Harman Kardon Luna 2 is rated at IP67 (brief submersion), well ahead of the Marshall Stockwell 2 at IPX4 (splashing).

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).
