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 GRV-650L ranks #56, rated 3.3/5, at $149.95, $20.04 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Soundcore Boom 2 Plus is the better-sounding, deeper-bass pick. A fairly light stereo boombox, easy to carry to the beach or park. Its bass reaches about 39Hz before falling 10dB, against 47Hz for the Gemini GRV-650L. It is rated for 20 hours of battery against 9 for the Gemini GRV-650L. At 8.4 lbs (3.8 kg) it weighs much less than the Gemini GRV-650L at 15.7 lbs (7.1 kg). The tradeoff: Warm tuning meaning a rolled off treble and some upper bass boost.
Why pick the Gemini GRV-650L: A great value party speaker with an included wireless mic, remote, FM radio and water resistance. The catch: Not quite as deep bass as the top ranked speakers.
Buy the Soundcore Boom 2 Plus. It is rated higher for sound quality, and saving $20.04 with the Gemini GRV-650L does not make up for the sound-quality gap.
