Short answer: the JBL Partybox Encore 2. It ranks #4 of 100 boombox speakers by sound quality, rated 4.4/5, at $330. The W-King X10-1 ranks #85, rated 2.4/5, at $139.99, $190.01 cheaper, not enough of a saving to outweigh the sound-quality gap.
The JBL Partybox Encore 2 is the better-sounding, deeper-bass pick. 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 bass reaches about 42Hz before falling 10dB, against 63Hz for the W-King X10-1. It links with other speakers (Auracast), which the W-King X10-1 cannot. The catch: It still lacks some upper-bass punch and cannot match the scale of the larger PartyBoxes.
The W-King X10-1 is the longer-running, lighter pick. A 6.5 lbs (2.95 kg) stereo boombox with a 42-hour battery, 70W RMS of power, a measured 108dB maximum output and a USB power bank. It is rated for 42 hours of battery against 15 for the JBL Partybox Encore 2. At 6.5 lbs (2.95 kg) it weighs much less than the JBL Partybox Encore 2 at 14.1 lbs (6.4 kg). It is rated IPX6 against IPX4 for the JBL Partybox Encore 2. Watch for: Rolled off treble, not much bass.
Buy the JBL Partybox Encore 2. It is rated higher for sound quality, and saving $190.01 with the W-King X10-1 does not make up for the sound-quality gap.
