Short answer: the Harman Kardon Go + Play 3, if you are buying new. The Harman Kardon Go + Play 2 ranks higher than the W-King X20 (#23 vs #41 of 98 boombox speakers) but is discontinued; its replacement, the Harman Kardon Go + Play 3, is rated 4.4/5 at $385 and is still sold new.
The Harman Kardon Go + Play 2 is the better-sounding, lighter pick. Claimed 8 hours (manufacturer specified) battery life, up to 99db and stereo playback make its feature set practical for its intended room or portable use. At 5.3 lbs (2.4 kg) it weighs much less than the W-King X20 at 15.9 lbs (7.2 kg). It links with other speakers (Wireless Dual Sound), which the W-King X20 cannot. The catch: Not as loud as others.
The W-King X20 is the louder, longer-running choice. Alan Ross Reviews measured it at 112dB at full volume, against 99dB for the Harman Kardon Go + Play 2. It is rated for 24 hours of battery against 8 for the Harman Kardon Go + Play 2. It is rated IPX6, while the Harman Kardon Go + Play 2 has no water resistance. Watch for: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.
Buy the Harman Kardon Go + Play 3, the replacement for the discontinued Harman Kardon Go + Play 2; it is rated higher for sound quality than the W-King X20.
