Short answer: the Turtlebox Grande if sound quality matters most, the W-King X10 if price matters most, though neither ranks well in its class. The Turtlebox Grande ranks #80 of 112 boombox speakers, rated 2.6/5, at $730. The W-King X10 ranks #93, rated 2.3/5, at $80, $650 cheaper. Both are rated below 3.0/5 among the 112 boombox speakers; for better sound, the Tribit Stormbox Blast ranks #2 at $179.99.
The Turtlebox Grande is the better-sounding pick. 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 X10 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 X10 is the longer-running, lighter choice. A cheap, waterproof stereo boombox with a very long battery, loud output and a power bank for charging your phone. It is rated for 42 hours of battery against 25 for the Turtlebox Grande. At 6.5 lbs (2.95 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. Watch for: Heavily rolled off treble, less bass than the top ranked.
Buy the Turtlebox Grande if sound quality is the priority over the price, or the W-King X10 if the price is the priority over sound quality.
