Short answer: the W-King D8. It ranks #58 of 115 large speakers by sound quality, rated 3.5/5, at $79.99; the Marshall Stockwell III ranks #79, rated 3.0/5, and costs $249.99, so there is not much of a tradeoff to weigh.
The Marshall Stockwell III is the longer-running, lighter pick. A stylish, rugged speaker with a very long battery you can swap yourself, a detailed app EQ, and power bank charging. It is rated for 40 hours of battery against 24 for the W-King D8. At 2.9 lbs (1.3 kg) it weighs much less than the W-King D8 at 5.4 lbs (2.43 kg). It supports AAC Bluetooth, which the W-King D8 lacks. The tradeoff: Highs are recessed by default and need the treble control maxed to compensate, still lacking detail even then.
The W-King D8 is the better-sounding, tougher option. An affordable stereo boombox with four drivers, waterproofing, and a long battery for backyard and beach playlists. It is rated IPX7 against IP55 for the Marshall Stockwell III.
Buy the W-King D8. It is rated higher for sound quality than the Marshall Stockwell III and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
