Short answer: the W-King D20. It ranks #41 of 112 boombox speakers by sound quality (rated 3.6/5) at $193 and is still sold new; the Bumpboxx Flare 6 ranks #82 (rated 2.6/5) and is discontinued, so it is only an option used.
The W-King D20 is the better-sounding, longer-running pick. A loud stereo party speaker with two wireless microphones, a 24 hour battery and water resistance. It is rated for 24 hours of battery against 12 for the Bumpboxx Flare 6. It has an adjustable EQ, which the Bumpboxx Flare 6 lacks. The tradeoff: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.
Why pick the Bumpboxx Flare 6: A retro styled stereo party speaker with water resistance and a 12 hour battery. Watch for: There is no companion app.
Buy the W-King D20. It is rated higher for sound quality and still sold new, while the Bumpboxx Flare 6 is discontinued.
