Short answer: the Tribit Stormbox Lava. It ranks #3 of 97 large speakers by sound quality, rated 4.6/5, at $100; the Marshall Kilburn III ranks #41, rated 3.8/5, and costs $379.99, which makes this an easy call rather than a real tradeoff.
The Tribit Stormbox Lava is the better-sounding, tougher choice. 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. It is rated IP67 against IP54 for the Marshall Kilburn III. The tradeoff: XBass can make the low end muddy and obscure vocals, while the deepest notes lose authority and clarity falls at maximum volume.
The Marshall Kilburn III is the longer-running option. Spacious soundstage with broad stereo dispersion from Marshall’s True Stereophonic multi-driver layout, delivering warm, room-filling sound with 45Hz bass extension. It is rated for 50 hours of battery against 24 for the Tribit Stormbox Lava. It links with other speakers (Auracast), which the Tribit Stormbox Lava cannot. The tradeoff: Noticeable dips in the midrange compromise frequency response neutrality, making vocals and acoustic instruments sound somewhat recessed or muffled compared to more linear competitors like the JBL Xtreme 4 unless the bass dial is dialed back.
Buy the Tribit Stormbox Lava. It is rated higher for sound quality than the Marshall Kilburn III and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

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

Marshall Kilburn III: $379.99 Amazon eBay
Older model: the Marshall Kilburn II (ranked lower, rated 3.8/5).
Pros: Spacious soundstage with broad stereo dispersion from Marshall’s True Stereophonic multi-driver layout, delivering warm, room-filling sound with 45Hz bass extension. Independent physical bass and treble dials allow quick tonal adjustments on the fly, backed by app-based EQ and placement compensation. Battery life is outstanding at up to 50+ hours with USB-C power-bank charging, IP54 splash resistance, 3.5mm aux input, and Bluetooth 5.3 with Auracast broadcast support. Measured bass extension of 45Hz (-10dB).
Cons: Noticeable dips in the midrange compromise frequency response neutrality, making vocals and acoustic instruments sound somewhat recessed or muffled compared to more linear competitors like the JBL Xtreme 4 unless the bass dial is dialed back. Kilburn II retains slightly punchier perceived loudness at maximum volume due to a more aggressive V-shaped contour. At 2.85 kg with only IP54 splash resistance, it is heavy and cannot withstand water immersion. Lacks a built-in microphone and LDAC codec support.
