Short answer: the Zealot ZE51. It ranks #16 of 112 boombox speakers by sound quality (rated 4.1/5) at $235.33 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 Zealot ZE51 is the better-sounding choice. A big stereo boombox with clean, wide sound and low distortion at high volume for outdoor parties. The tradeoff: The Zealot ZE41 still wins on raw bass depth and price.
The Soundcore Rave Party 2 is the longer-running, lighter choice. A stereo party speaker with LED lights, a karaoke mic input and linking for up to 100 speakers. It is rated for 16 hours of battery against 4 for the Zealot ZE51. At 10.1 lbs (4.6 kg) it weighs much less than the Zealot ZE51 at 26 lbs (11.81 kg). Watch for: Only IPX4 splash resistance, and bass extension seems limited.
Buy the Zealot ZE51. It is rated higher for sound quality and still sold new, while the Soundcore Rave Party 2 is discontinued.
