Short answer: the Tribit Stormbox Blast 2. It ranks #31 of 113 boombox speakers by sound quality, rated 3.8/5, at $279.99. The Gemini GGO-650L ranks #86, rated 2.5/5, at $99.95, $180.04 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Tribit Stormbox Blast 2 is the better-sounding, deeper-bass choice. A big, waterproof party speaker with deep bass, very high volume, a 30 hour battery and two mic inputs. Its bass reaches about 40Hz before falling 10dB, against 56Hz for the Gemini GGO-650L. It is rated for 30 hours of battery against 10 for the Gemini GGO-650L. It is rated IP67 against IPX5 for the Gemini GGO-650L. The catch: Sounds quite muddy with the boosted lower and upper bass.
The Gemini GGO-650L is the lighter choice. 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 Tribit Stormbox Blast 2 at 19.2 lbs (8.7 kg).
Buy the Tribit Stormbox Blast 2. It is rated higher for sound quality, and saving $180.04 with the Gemini GGO-650L does not make up for the sound-quality gap.
