Short answer: the Boombox 3, if the price gap is acceptable. It ranks #21 of 71 boombox speakers at $399; the T11 ranks #34 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.
