Short answer: the W-King D20. It ranks #39 of 98 boombox speakers by sound quality, rated 3.6/5, at $193; the JBL Partybox On the Go ranks #64, rated 3.0/5, and costs $249.95, which makes this an easy call rather than a real tradeoff.
The W-King D20 is the better-sounding, deeper-bass pick. Comes with 2 wireless microphones. Its bass reaches about 42Hz before falling 10dB, against 49Hz for the JBL Partybox On the Go. It is rated for 24 hours of battery against 6 for the JBL Partybox On the Go. It is rated IPX6 against IPX4 for the JBL Partybox On the Go. The tradeoff: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.
Why pick the JBL Partybox On the Go: JBL Partybox On the Go uses 5.1” woofer + tweeters. The catch: Bass is limited by its 49Hz specification.
Buy the W-King D20. It is rated higher for sound quality than the JBL Partybox On the Go and costs less, which makes it the one to get unless you need something the other one does better.
