Short answer: the Tribit Stormbox Lava for bass and value. Independent reviews find it gets loud with impactful bass and, with careful EQ, relatively clean mids and highs, plus a measured 44Hz -10dB bass point and IP67 protection at $119.99. The Stockwell III is lighter at 2.9 lbs (1.3 kg) against 5.2 lbs (2.37 kg) and its 40+ hour battery runs 16 hours longer, but it costs $249.99 and is only IP55.
A $119.99 budget speaker outranking a $249.99 premium one is the story here. The Stockwell III offers a lighter 2.9 lbs (1.3 kg) cabinet, a parametric EQ app, wall/corner compensation, and a 40+ hour battery that doubles as a power bank, at IP55. The Stormbox Lava offers a measured 44Hz -10dB bass point, 10-band app EQ, and a 24-hour battery at IP67, for $119.99.
Choose the Stormbox Lava for bass and value: Independent reviews find it gets loud with impactful bass and, with careful EQ, relatively clean mids and highs, all at less than half the Stockwell III’s price and with better water resistance.
Choose the Stockwell III for portability and longer runtime: At 2.9 lbs (1.3 kg) versus the Lava’s 5.2 lbs (2.37 kg), plus a battery that runs 16 hours longer and doubles as a power bank, it’s the easier speaker to actually carry around all day.
