Short answer: the W-King X20. It ranks #43 of 113 boombox speakers by sound quality (rated 3.5/5) at $229.99 and is still sold new; the Bumpboxx Flare 8 ranks #82 (rated 2.6/5) and is discontinued, so it is only an option used. The Bumpboxx Flare 8’s replacement, the Bumpboxx Flare8 Pro, is rated 2.8/5 at $449.
The W-King X20 is the better-sounding, longer-running pick. A loud stereo party speaker with a large subwoofer, a 24 hour battery with power bank, and water resistance. It is rated for 24 hours of battery against 12 for the Bumpboxx Flare 8. The tradeoff: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.
Why pick the Bumpboxx Flare 8: A retro styled party speaker with FM radio, water resistance and high volume for small outdoor parties. Watch for: Bass is thuddy rather than deep or controlled, and there is no app to improve the tuning.
Buy the W-King X20. It is rated higher for sound quality; the Bumpboxx Flare 8 is no longer sold new.
