Short answer: the Boombox 3, if the price gap is acceptable. It ranks #27 of 113 boombox speakers at $349.95; the T11 ranks #55 at $116.57, $233.38 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.
