#71 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.

How it compares: Just above it: W-King D10 - $610 cheaper, 17 more hours of battery life. Just below it: Bumpboxx Flare 8 - $330 cheaper, 13 fewer hours of battery life.
