Short answer: the Onn Medium Party Speaker Gen 2. It ranks #65 of 112 boombox speakers by sound quality, rated 3.1/5, at $90; the Turtlebox Grande ranks #80, rated 2.6/5, and costs $730, so there is not much of a tradeoff to weigh.
What the Turtlebox Grande does well: A rugged, submersible, crush-proof speaker with a 10 inch woofer and a battery that lasts for days. It plays in stereo from a single unit, unlike the Onn Medium Party Speaker Gen 2. Watch for: In YouTube sound samples it sounds only okay, and bass is shallow for a 10 inch woofer, only down 10dB at about 55Hz.
The Onn Medium Party Speaker Gen 2 is the better-sounding, lighter choice. An affordable waterproof party speaker with a big woofer, lights, a karaoke mic input and FM radio. At 11 lbs (5 kg) it weighs much less than the Turtlebox Grande at 18.8 lbs (8.53 kg). The catch: Lacking detail compared to the Onn Large Party gen 2 and not as deep of bass.
Buy the Onn Medium Party Speaker Gen 2. It is rated higher for sound quality than the Turtlebox Grande and costs less, which makes it the one to get unless you need something the other one does better.
