Short answer: the Tribit Stormbox Lava for bass, the EarFun Uboom X for tuning. The Lava delivers fantastic bass extension at $139.99 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.
One note: the EarFun Uboom X is discontinued, but it still ranks #1 of 113 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 ($139.99) suits a large speaker instead.
