Short answer: the Zealot S95. It ranks #37 of 113 boombox speakers by sound quality, rated 3.7/5, at $157.41. The Gemini GGO-650L ranks #86, rated 2.5/5, at $99.95, $57.46 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Zealot S95 is the better-sounding, deeper-bass pick. An affordable stereo boombox with water resistance, a power bank output and linking for up to 100 speakers. Its bass reaches about 45Hz before falling 10dB, against 56Hz for the Gemini GGO-650L. It links with other speakers (PartyAdd up to 100 speakers), which the Gemini GGO-650L cannot. It has an adjustable EQ, which the Gemini GGO-650L lacks. The tradeoff: A little rolled off up top and not that balanced through the rest of the range.
Why pick the Gemini GGO-650L: An inexpensive stereo party speaker with a big woofer, water resistance and a 10 hour battery. The tradeoff: Bass is limited by its ~56Hz specification.
Buy the Zealot S95. It is rated higher for sound quality, and the $57.46 saving on the Gemini GGO-650L is not enough to make up the difference.
