Short answer: the W-King D10, though neither ranks well in its class. It ranks #79 of 112 boombox speakers by sound quality, rated 2.7/5, at $84.97; the Turtlebox Grande ranks #80, rated 2.6/5, and costs $730, which makes this an easy call rather than a real tradeoff. Both are rated below 3.0/5 among the 112 boombox speakers; for better sound, the Tribit Stormbox Blast ranks #2 at $179.99.
What the Turtlebox Grande does well: A rugged, submersible, crush-proof speaker with a 10 inch woofer and a battery that lasts for days. It links with other speakers (Turtlebox Party Mode), which the W-King D10 cannot. 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.
The W-King D10 is the longer-running, lighter choice. An inexpensive boombox with a 42 hour battery, water resistance, a power bank and a karaoke mic input. It is rated for 42 hours of battery against 25 for the Turtlebox Grande. At 7.9 lbs (3.6 kg) it weighs much less than the Turtlebox Grande at 18.8 lbs (8.53 kg). It has an adjustable EQ, which the Turtlebox Grande lacks. The tradeoff: Upper bass boost, bass not that deep.
Buy the W-King D10. It is rated higher for sound quality than the Turtlebox Grande and costs less, so only choose the other one for a particular feature it does better.
