Short answer: the Gemini GGO-650L, though neither ranks well in its class. It ranks #86 of 113 boombox speakers by sound quality, rated 2.5/5, at $99.95. The W-King X10 ranks #94, rated 2.3/5, at $80, $19.95 cheaper, not enough of a saving to outweigh the sound-quality gap. Both are rated below 3.0/5 among the 113 boombox speakers; for better sound, the Bugani Brief Pro ranks #28 at $99.98.
The case for the Gemini GGO-650L: An inexpensive stereo party speaker with a big woofer, water resistance and a 10 hour battery. The catch: Bass is limited by its ~56Hz specification.
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 10 for the Gemini GGO-650L. At 6.5 lbs (2.95 kg) it weighs noticeably less than the Gemini GGO-650L at 9.3 lbs (4.2 kg). It has an adjustable EQ, which the Gemini GGO-650L lacks. The catch: Heavily rolled off treble, less bass than the top ranked.
Buy the Gemini GGO-650L. It is rated higher for sound quality, and saving $19.95 with the W-King X10 does not make up for the sound-quality gap.
