Short answer: the JBL Partybox Encore 2. It ranks #4 of 89 boombox speakers by sound quality, rated 4.4/5, at $330. The onn Pro X Large Boom Boombox ranks #43, rated 3.4/5, at $199, $131 cheaper, a saving that is not big enough to make up the sound-quality gap.
The case for the JBL Partybox Encore 2: The Encore 2 improves the original with dome tweeters, a less boomy balance, slightly deeper bass, longer battery life and two included wireless microphones. The tradeoff: It still lacks some upper-bass punch and cannot match the scale of the larger PartyBoxes.
What the onn Pro X Large Boom Boombox does well: High rated power for the price at 180W RMS (540W peak). Watch for: Bass not as deep as higher ranked speakers like the JBL Boombox 3, JBL Boombox 4, or Tribit Stormbox Blast.
Buy the JBL Partybox Encore 2. It is rated higher for sound quality, and the $131 you would save on the onn Pro X Large Boom Boombox does not close the gap.
If water resistance matters to you, the onn Pro X Large Boom Boombox at IP67 (brief submersion) holds up far better than the JBL Partybox Encore 2 at IPX4 (splashing).

JBL Partybox Encore 2: $330 Sam’s Club eBay
Older model: the JBL Partybox Encore (ranked lower, rated 4.3/5).
Pros: The Encore 2 improves the original with dome tweeters, a less boomy balance, slightly deeper bass, longer battery life and two included wireless microphones. Its compact karaoke-ready design and 7-band EQ make it more adaptable indoors than the earlier Encore.
Cons: It still lacks some upper-bass punch and cannot match the scale of the larger PartyBoxes. The main value is compact karaoke convenience rather than full-range party output.
