Short answer: the Harman Kardon Onyx Studio 6. It ranks #11 of 73 boombox speakers by sound quality at $130; the W-King T11 ranks #35 and costs $150, 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 T11 offers: 100W RMS output with 240W peak power, 112dB max volume, IPX6 waterproof, 10-hour battery life, power bank function, dual 5.25-inch woofers with tweeters and passive radiators, EQ with multiple modes, microphone and karaoke input, MicroSD and USB playback, TWS stereo pairing Watch for: Almost as deep of bass as the top ranked ones. A little hollow sounding. Wall wart charger.
Buy the Harman Kardon Onyx Studio 6. It ranks higher for sound quality than the W-King T11 and costs less, so the other one has nothing left to offer.
