Short answer: the Harman Kardon Luna. It ranks #24 of 150 medium speakers by sound quality, rated 4.0/5, at $290.99. The LG Xboom Go PL5 ranks #125, rated 2.4/5, at $179, $111.99 cheaper, a saving that is not big enough to make up the sound-quality gap.
Why pick the Harman Kardon Luna: Harman Kardon Luna uses 48mm x 90mm woofer, 20mm tweeter. The tradeoff: Bass is limited by its 57Hz specification.
The case for the LG Xboom Go PL5: 18 hour battery life; IPX5 rated. The tradeoff: Barely any bass.
Buy the Harman Kardon Luna. It is rated higher for sound quality, and the $111.99 you would save on the LG Xboom Go PL5 does not close the gap.

The Two Speakers In Full
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.
