Short answer: the Teufel Boomster 4. It ranks #44 of 89 boombox speakers by sound quality (rated 3.4/5); the Turtlebox Grande ranks #69 (rated 2.6/5).
Why pick the Teufel Boomster 4: Warmer and more open than the Boomster 2021 it replaces, with nicer, less harsh highs, a wide stereo image from its three-way layout (two 20mm tweeters, two 65mm midrange drivers and a 110mm woofer with passive radiators) and good detail. Watch for: Side by side with the Boomster 2021 the sound barely changed, and it has a little less deep bass.
What the Turtlebox Grande does well: 10-inch woofer. The catch: 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 Teufel Boomster 4. It is rated higher for sound quality than the Turtlebox Grande.

Teufel Boomster 4: €249.99 Teufel eBay
Older models: the Teufel Boomster 2021 (ranked lower, rated 3.4/5) and the Teufel Boomster NG (2017) (ranked lower, rated 3.2/5).
Pros: Warmer and more open than the Boomster 2021 it replaces, with nicer, less harsh highs, a wide stereo image from its three-way layout (two 20mm tweeters, two 65mm midrange drivers and a 110mm woofer with passive radiators) and good detail. Its new treble control and remote let you tame the top end. DAB+ and FM radio, a claimed 23 hours of battery at medium volume, IPX5, Bluetooth 5.0 with AAC and aptX HD, multipoint, an aux input, USB-C charging and stereo pairing.
Cons: Side by side with the Boomster 2021 the sound barely changed, and it has a little less deep bass. Against the Harman Kardon Go + Play 3 it sounds sharper and thinner, with weaker bass and a less natural stereo image, and its bass drops off at full volume. At 3.75 kg it is heavy for its size, it has no power bank output, and IPX5 is a step down from the older model’s IPX7.

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.
