Short answer: the Marshall Kilburn II. It ranks #39 of 82 large speakers by sound quality, rated 3.8/5, at $279. The LG Xboom XG7 ranks #74, rated 2.4/5, at $120, $159 cheaper, a saving that is not big enough to make up the sound-quality gap.
The case for the Marshall Kilburn II: 20W Class D amp + dual 8W tweeters. The tradeoff: Boosted upper bass, not very detailed, not as deep bass as competitors, upper mids peak.
Why pick the LG Xboom XG7: Impressive 24-hour battery life. Watch for: Peaky midrange, rolled off treble.
Buy the Marshall Kilburn II. It is rated higher for sound quality, and the $159 saving on the LG Xboom XG7 is not enough to make up the difference.
If water resistance matters to you, the LG Xboom XG7 at IPX7 (brief submersion) holds up far better than the Marshall Kilburn II at IPX2 (light drips).
