Short answer: the Yeahbox Sonic Boom Ultra. It ranks #11 of 112 boombox speakers by sound quality (rated 4.2/5) at $388 and is still sold new; the Soundcore Rave Party 2 ranks #64 (rated 3.1/5) and is discontinued, so it is only an option used.
The Yeahbox Sonic Boom Ultra is the better-sounding, longer-running pick. A massively loud boombox with deep bass, long battery life, and HDMI ARC so it can double as a TV soundbar. It is rated for 24 hours of battery against 16 for the Soundcore Rave Party 2. It is rated IPX6 against IPX4 for the Soundcore Rave Party 2. The catch: The 500W peak-power rating doesn’t fully hold up: it gets noisy above roughly 80-90% volume, and the midrange isn’t fully refined, sometimes sitting a touch too forward.
The Soundcore Rave Party 2 is the lighter option. A stereo party speaker with LED lights, a karaoke mic input and linking for up to 100 speakers. At 10.1 lbs (4.6 kg) it weighs much less than the Yeahbox Sonic Boom Ultra at 24.3 lbs (11 kg). It links with other speakers (PartyCast 2.0 up to 100 speakers), which the Yeahbox Sonic Boom Ultra cannot. Watch for: Only IPX4 splash resistance, and bass extension seems limited.
Buy the Yeahbox Sonic Boom Ultra. It is rated higher for sound quality; the Soundcore Rave Party 2 is no longer sold new.
