Short answer: the W-King X20. It ranks #43 of 113 boombox speakers by sound quality, rated 3.5/5, at $229.99. The Gemini GGO-650L ranks #86, rated 2.5/5, at $99.95, $130.04 cheaper, which does not close the gap in sound quality.
The W-King X20 is the better-sounding, deeper-bass pick. A loud stereo party speaker with a large subwoofer, a 24 hour battery with power bank, and water resistance. Its bass reaches about 42Hz before falling 10dB, against 56Hz for the Gemini GGO-650L. It is rated for 24 hours of battery against 10 for the Gemini GGO-650L. It has an adjustable EQ, which the Gemini GGO-650L lacks. Watch for: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.
The Gemini GGO-650L is the lighter option. An inexpensive stereo party speaker with a big woofer, water resistance and a 10 hour battery. At 9.3 lbs (4.2 kg) it weighs much less than the W-King X20 at 15.9 lbs (7.2 kg).
Buy the W-King X20. It is rated higher for sound quality, and saving $130.04 with the Gemini GGO-650L does not make up for the sound-quality gap.
