Short answer: the Turtlebox Grande, if you are buying new, though neither ranks well in its class. The Bumpboxx Flare 6 measures as well as it (#82 vs #80 of 112 boombox speakers, 2.6/5 vs 2.6/5) but is discontinued, so only consider it used; the Turtlebox Grande is still sold new at $730. Both are rated below 3.0/5 among the 112 boombox speakers, so if sound quality matters, consider the Tribit Stormbox Blast instead, ranked #2 at $179.99.
The Turtlebox Grande is the longer-running option. A rugged, submersible, crush-proof speaker with a 10 inch woofer and a battery that lasts for days. It is rated for 25 hours of battery against 12 for the Bumpboxx Flare 6. It links with other speakers (Turtlebox Party Mode), which the Bumpboxx Flare 6 cannot. Watch for: In YouTube sound samples it sounds only okay, and bass is shallow for a 10 inch woofer, only down 10dB at about 55Hz.
The Bumpboxx Flare 6 is the lighter option. A retro styled stereo party speaker with water resistance and a 12 hour battery. At 13 lbs (5.9 kg) it weighs noticeably less than the Turtlebox Grande at 18.8 lbs (8.53 kg).
Buy the Turtlebox Grande new; the Bumpboxx Flare 6 is no longer sold new, so it only makes sense as a used find.
