These are not really the same size class, and that is the honest framing here. The Tribit Stormbox Lava ranks #3 of 82 large speakers by sound quality at $100; the Sony ULT Field 1 ranks #81 of 144 medium speakers by sound quality at $98.

Why pick the Tribit Stormbox Lava: A powerful, IP67-rated portable speaker with a measured 44Hz -10dB bass point, 10-band app EQ, aux input and 24-hour claimed battery life. The catch: XBass can make the low end muddy and obscure vocals, while the deepest notes lose authority and clarity falls at maximum volume.
Why pick the Sony ULT Field 1: IP67 rated, survives drops and 1m submersion. The tradeoff: Upper midrange peak, rolled off treble.
Buy the Tribit Stormbox Lava at $100 if you want a large speaker. Buy the Sony ULT Field 1 at $98 if you want a medium speaker instead.
Battery life favors the Tribit Stormbox Lava: rated for 24 hours against 12 hours for the Sony ULT Field 1.

The Two Speakers In Full
Tribit Stormbox Lava: $100 Amazon AliExpress eBay
Pros: A powerful, IP67-rated portable speaker with a measured 44Hz -10dB bass point, 10-band app EQ, aux input and 24-hour claimed battery life. Independent reviews find that it gets loud with impactful bass, and careful EQ or current firmware can produce relatively clean sound through the mids and highs. Measured bass extension of 44Hz (-10dB).
Cons: XBass can make the low end muddy and obscure vocals, while the deepest notes lose authority and clarity falls at maximum volume. It is heavy for its size, its front-facing design has a narrow soundstage, and one review noted a brief sound interruption while changing volume; use a restrained EQ rather than expecting neutral sound out of the box.
Setup: Try out the Alan Ross EQ’s at this timestamp in his video There’s also a max bass EQ from Oluv and you can turn down the lowest slider for it to be more neutral
