Short answer: the Bumpboxx Flare 8, though neither ranks well in its class. Both are rated 2.6/5 for sound quality (#58 and #57 of 76 boombox speakers), and the Bumpboxx Flare 8 costs $400 against $730 for the Turtlebox Grande, with sound quality a draw, the lower price decides it. Both are rated below 3.0/5 among the 76 boombox speakers, so if sound quality matters, consider the Tribit Stormbox Blast instead, ranked #2 at $179.99.
Why pick the Turtlebox Grande: 10-inch woofer. The catch: They pretty much lie about all their specs and sound just okay in all youtube sound samples.
The case for the Bumpboxx Flare 8: A retro-styled, 8.6kg party speaker with useful real-world features: IPX6 splash resistance, FM radio, USB and microSD playback, aux input, TWS pairing and a claimed 118dB maximum output. The catch: Bass is thuddy rather than deep or controlled, and there is no app to improve the tuning.
Buy the Bumpboxx Flare 8. Both are rated the same for sound quality, and it costs $330 less than the Turtlebox Grande.
If battery life is a priority, the Turtlebox Grande is rated for 25 hours versus 12 hours for the Bumpboxx Flare 8.

The Two Speakers In Full
Turtlebox Grande: $730.00 Amazon eBay
Pros: 10-inch woofer. IP67 submersible shell with crush-proof ABS exterior. 158Wh battery provides ~3 days of playback. Bluetooth 5.4, party mode (100+ speakers). Measured bass extension of ~55Hz (-10dB).
Cons: They pretty much lie about all their specs and sound just okay in all youtube sound samples. Only 100w will never hit 126db at a reasonable measuring distance. Putting your db meter right against the speaker doesn’t count, 1 meter distance is the standard. Barely any bass for a 10” woofer. Overpriced and not worth it.

Bumpboxx Flare 8: $400 Bumpboxx eBay
Pros: A retro-styled, 8.6kg party speaker with useful real-world features: IPX6 splash resistance, FM radio, USB and microSD playback, aux input, TWS pairing and a claimed 118dB maximum output. It can play much louder than compact Bluetooth speakers and is easy to aim at a small outdoor gathering.
Cons: Bass is thuddy rather than deep or controlled, and there is no app to improve the tuning. Owner reports also raise reliability concerns, including noisy or intermittent volume controls and sound cutting out at high volume. It is a fun-looking niche product, not a sound-quality or durability leader.
