Short answer: the Soundcore Boom 2 Plus. It ranks #39 of 113 boombox speakers by sound quality, rated 3.6/5, at $169.99. The Gemini GGO-650L ranks #86, rated 2.5/5, at $99.95, $70.04 cheaper, which does not close the gap in sound quality.
The Soundcore Boom 2 Plus is the better-sounding, deeper-bass choice. A fairly light stereo boombox, easy to carry to the beach or park. Its bass reaches about 39Hz before falling 10dB, against 56Hz for the Gemini GGO-650L. It is rated for 20 hours of battery against 10 for the Gemini GGO-650L. It is rated IPX7 against IPX5 for the Gemini GGO-650L. Watch for: Warm tuning meaning a rolled off treble and some upper bass boost.
The case for 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 Soundcore Boom 2 Plus. It is rated higher for sound quality, and the $70.04 you would save on the Gemini GGO-650L does not close the gap.
