Short answer: the B&O Beosound A1 3rd gen. It ranks #18 of 151 medium speakers by sound quality, rated 4.1/5, at $380.15. The Harman Kardon Luna ranks #24, rated 4.0/5, at $290.99, $89.16 cheaper, a saving that is not big enough to make up the sound-quality gap.
What the Harman Kardon Luna gets right: Pretty balanced sound besides the boosted bass. The catch: Not stereo.
Buy the B&O Beosound A1 3rd gen. It is rated higher for sound quality, and the $89.16 you would save on the Harman Kardon Luna does not close the gap.
If battery life is a priority, the B&O Beosound A1 3rd gen is rated for 24 hours versus 12 hours for the Harman Kardon Luna.

Harman Kardon Luna: $290.99 Amazon eBay
Newer model: the Harman Kardon Luna 2, ranked higher, rated 4.1/5.
Pros: Harman Kardon Luna uses 48mm x 90mm woofer, 20mm tweeter. Its 1.13 kg, claimed 12 hours (Manufacturer specified) battery life, IP67 protection and mono playback make it a practical option for its intended room or portable use. The sound is fairly balanced apart from the boosted bass. Measured bass extension of 57Hz (-10dB).
Cons: Bass is limited by its 57Hz specification. There is no companion app. No EQ adjustment. Boosted bass, and less detailed than higher-ranked speakers.
