Short answer: the Tribit Stormbox Lava for bass, the Earfun Uboom X for tuning. The Lava delivers fantastic bass extension at $100 and its main drawback is being quite heavy for the size. The Oluv-tuned Uboom X costs more at $159.99, and you will want to replace its horrible out-of-the-box 0.33 firmware and EQ.
The case for the Earfun Uboom X: Tuned by Oluv and he knocked it out of the park again. Set against that: The out of the box 0.33 firmware and EQ sounds horrible.
What the Tribit Stormbox Lava gets right: Fantastic bass extension. The catch: Quite heavy for the size.
One note: the Earfun Uboom X is discontinued, but it still ranks #1 of 75 boombox speakers by sound quality, ahead of most of what is still sold new, so it is worth considering used.
Buy the Earfun Uboom X ($159.99) for a boombox speaker; the Tribit Stormbox Lava ($100) suits a large speaker instead.

The Two Speakers In Full
Earfun Uboom X: $159.99 Discontinued Myearfun eBay
Pros: Tuned by Oluv and he knocked it out of the park again. Deeper bass than the Stormbox Blast. Extremely neutral, possibly the best of any modern Bluetooth speaker slightly behind the Vifa Helsinki. This is the only speaker that sounds correct at every single volume level due to Oluv’s individual EQ settings at each volume level. Other speakers will need a different EQ at each volume level. Amazing sounding at low levels as it boosts bass and treble at low levels to account for the equal-loudness contour. Just considering the midrange and treble, this speaker is better sounding than the Earfun Uboom L. Measured bass extension of ~38Hz (-10dB).
Cons: The out of the box 0.33 firmware and EQ sounds horrible. Some users have reported sound interruption issues when running two in TWS, though not on every source device, and disabling AAC resolves it where it occurs. Discontinued.
Setup: Please update it using the Earfun app (Android or iOS) and select an Oluv EQ. The Earfun app has sound profiles created by Oluv for Studio, Indoor, Indoor+, Outdoor, Outdoor+, BOOM xxX, and Ground 0 which are all fantastic. Oluv has a newer firmware pack that brings it up a few more notches of neutral

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
