Short answer: the Aiwa Exos-10. It ranks #38 of 89 boombox speakers by sound quality, rated 3.5/5, at $159.99; the Turtlebox Grande ranks #69, rated 2.6/5, and costs $730, so there is not much of a tradeoff to weigh.
The case for the Aiwa Exos-10: Clear, clean treble with good separation of instruments and vocals, and no distortion even near full volume in a side by side test against the W-King X20, where it kept up in loudness at 90%. The catch: It lacks deep bass: even with bass maxed it rolls off around 50Hz, where the W-King X20 and Zealot boomboxes reach deeper, and it is about 2dB quieter at full volume.
What the Turtlebox Grande does well: 10-inch woofer. The tradeoff: In YouTube sound samples it sounds only okay, and bass is shallow for a 10 inch woofer, only down 10dB at about 55Hz.
Buy the Aiwa Exos-10. It is rated higher for sound quality than the Turtlebox Grande and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
Battery life favors the Turtlebox Grande: rated for 25 hours against 12 hours for the Aiwa Exos-10.

The Two Speakers In Full
Aiwa Exos-10: $159.99 Amazon eBay
Older model: the Aiwa Exos-9 (ranked higher, rated 4.2/5).
Pros: Clear, clean treble with good separation of instruments and vocals, and no distortion even near full volume in a side by side test against the W-King X20, where it kept up in loudness at 90%. A 200W RMS tri-amplified design with a 6.5” woofer and four passive radiators, FM radio with presets, aux and USB inputs, a remote, analog-style VU meters and Party Sync with 100+ speakers.
Cons: It lacks deep bass: even with bass maxed it rolls off around 50Hz, where the W-King X20 and Zealot boomboxes reach deeper, and it is about 2dB quieter at full volume. Owners comparing it with the Aiwa Exos 9 it replaces find the older model clearer with tighter bass, and the Exos 10 drops the Exos 9’s 5-band EQ (only bass and treble) and removable battery. Claimed battery life is 12 hours.

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: In YouTube sound samples it sounds only okay, and bass is shallow for a 10 inch woofer, only down 10dB at about 55Hz. It is rated at just 86W, and like the smaller Turtleboxes it won’t reach its claimed 126dB at a standard one meter distance. Expensive for what it delivers. It charges only from its own barrel plug adapter, not USB-C.
