Short answer: the Harman Kardon Onyx Studio 6. It ranks #11 of 73 boombox speakers by sound quality at $130; the W-King X10-1 ranks #61 and costs $143, which makes this an easy call rather than a real tradeoff.
What the Harman Kardon Onyx Studio 6 offers: Warm sound with boosted bass. Oluv liked it slightly better than the newer Onyx 7. Watch for: 8 hour battery at medium volume. Not at loud as others.
What the W-King X10-1 offers: 70W RMS output with 120W peak power, 108dB max volume, exceptional 42-hour battery life with power bank, IPX6 waterproof, Bluetooth 5.0 with 100ft range, EQ with indoor/outdoor modes, dual subwoofers with tweeters and passive radiators, TWS stereo pairing, MicroSD and USB playback, AUX input, built-in microphone Watch for: Rolled off treble, not much bass.
Buy the Harman Kardon Onyx Studio 6. It ranks higher for sound quality than the W-King X10-1 and costs less, so the other one has nothing left to offer.
If sound quality matters at all to you, skip the W-King X10-1. It ranks near the bottom of the 73 boombox speakers, so look higher up the list instead.
If battery life is a priority, the W-King X10-1 is rated for 42 hours versus 8 hours for the Harman Kardon Onyx Studio 6.
