These sit in different size classes, so this is not a straight ranking comparison. The Turtlebox Grande ranks #56 of 75 boombox speakers by sound quality at $700; the Bose S1 Pro+ ranks #16 of 51 party speakers by sound quality at $699.
What the Turtlebox Grande offers: 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). Set against that: 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.
What the Bose S1 Pro gets right: Extremely compact and light with flexible placement options. Full sound with no lack of low-end output, crystal-clear audio quality. Three-channel mixer (2 mic/line + 1 line/Bluetooth). Auto EQ adjusts sound based on orientation. The tradeoff: With full range music, it becomes distorted above ⅔ volume. Better suited for voice amplification. Not as much deep bass as the Everse 8, midrange sounds reasonably balanced. Treble is pretty boosted. Not stereo. Designed for more loudness than deeper bass.
Buy the Turtlebox Grande at $700 for a boombox speaker, or the Bose S1 Pro+ at $699 for a party speaker instead.
If battery life is a priority, the Turtlebox Grande is rated for 25 hours versus 11 hours for the Bose S1 Pro+.
Water resistance is not close: the Turtlebox Grande is rated at IP67 (brief submersion), well ahead of the Bose S1 Pro+ at no water resistance.

The Two Speakers In Full
Turtlebox Grande: $700.00 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).
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.

Bose S1 Pro+: $699.00 Amazon eBay
Pros: Extremely compact and light with flexible placement options. Full sound with no lack of low-end output, crystal-clear audio quality. Three-channel mixer (2 XLR/quarter-inch combo mic-instrument + 1 line/Bluetooth), each with its own OLED display for quick treble/bass/reverb adjustment. Auto EQ adjusts sound based on orientation. Multiple angled surfaces for various positioning including tilted portrait mode, plus a line out to daisy-chain a second unit. Optional WT-XLR/WT-INST wireless transmitters dock, pair, and charge right in the speaker for a cable-free mic or instrument. Up to 11 hours battery life. Professional build quality. High efficiency drivers reach 2-3x the volume of typical speakers for the same wattage.
Cons: With full range music, it becomes distorted above ⅔ volume, and reviewers describe it as screeching at max volume. Better suited for voice amplification. Not as much deep bass as the Everse 8, midrange sounds reasonably balanced. Treble is pretty boosted. Not stereo. Designed for more loudness than deeper bass. Ports are fully exposed with no water resistance. Charges via a less common three-prong AC cable instead of the two-prong barrel cable most rivals use.
