Short answer: the Soundcore Boom 2 Plus. It ranks #39 of 112 boombox speakers by sound quality, rated 3.6/5, at $169.99. The Onn Medium Party Speaker Gen 2 ranks #65, rated 3.1/5, at $90, $79.99 cheaper, which does not close the gap in sound quality.
The Boom 2 Plus is the louder, better-tuned speaker. Two 4.5-inch woofers and two tweeters reach about 39Hz before falling 10dB, and Alan Ross measured 111dB. It plays in stereo, has a Pro EQ in the app and supports AAC, and at 8.4 lbs (3.8 kg) it is light for its size. Its warm tuning rolls off the treble, so EQ helps.
The Onn Medium Party Speaker Gen 2 is a cheap karaoke speaker. An 8-inch woofer, LED lights, a mic input with echo, an FM radio and an aux input come in an IPX7 cabinet. It lacks detail and deep bass compared with the Onn Large Party Gen 2, has no app or EQ, and is sold only in the US and Canada.
Buy the Soundcore Boom 2 Plus. It is rated higher for sound quality, and the $79.99 you would save on the Onn Medium Party Speaker Gen 2 does not close the gap.
