Short answer: the Marshall Middleton II. It ranks #31 of 82 large speakers by sound quality, rated 4.1/5, at $330. The Treblab HD-Max ranks #73, rated 2.4/5, at $129.97, $200.03 cheaper, a saving that is not big enough to make up the sound-quality gap.
The case for the Marshall Middleton II: Very deep bass for the size/weight. Watch for: Bass boosted which drowns out the midrange.
The case for the Treblab HD-Max: 50W incredibly loud for size with four monstrous drivers, tested 22.4-hour battery (25+ hours at 50% volume). The tradeoff: Boosted upper bass, not much lower bass.
Buy the Marshall Middleton II. It is rated higher for sound quality, and the $200.03 you would save on the Treblab HD-Max does not close the gap.
