Short answer: the Boombox 3, if the price gap is acceptable. It ranks #23 of 75 boombox speakers at $399; the T11 ranks #37 at $150, $249 less.
The T11 punches close to the top on bass depth for its price. Our notes describe it as almost as deep in bass as the top-ranked speakers, with a real spec sheet: 100W RMS output, dual 5.25-inch woofers, and karaoke input. Its complaints are a little hollow sounding and a wall-wart charger.
The Boombox 3 wins on features the T11 doesn’t have. IP67 water resistance, a genuine power bank function, and PartyBoost pairing, against dips in its own mid bass and a peak at 700Hz.
Buy the T11 for near-top bass depth at a fraction of the price. Buy the Boombox 3 for the water resistance and JBL’s ecosystem.
There is a real battery-life gap here: the JBL Boombox 3 is rated for 24 hours, the W-King T11 only 10 hours.

W-King T11: $113.53 Amazon Aliexpress eBay
Pros: A capable, weather-resistant party speaker with dual 5.25-inch woofers, a measured -10dB bass point around 43Hz, 112dB maximum output, mic/karaoke input, USB/microSD playback, TWS pairing and low-latency aux. Its deep bass and 5.1kg size make it a strong option when punch and portability matter more than audiophile refinement. Measured bass extension of 43Hz (-10dB).
Cons: The tuning can sound hollow through the mids, so deep bass does not always translate to natural vocals or instruments. There is no app-based fine EQ, battery life is only a claimed 10 hours, and the external power brick is less convenient than USB-C charging.
