Short answer: the B&O Beolit 20, if you are buying new. The Harman Kardon Go + Play 2 ranks higher than it (#23 vs #42 of 89 boombox speakers, 3.9/5 vs 3.4/5) but is discontinued, so only consider it used; the B&O Beolit 20 is still sold new at $749.
Why pick the Harman Kardon Go + Play 2: At 2.4 kg, Harman Kardon Go + Play 2 combines 2x 90mm (3.5”) woofers (front and rear firing) + 2x 20mm tweeters with Bluetooth. The catch: Bass is limited by its 40Hz specification.
Why pick the B&O Beolit 20: B&O Beolit 20 uses 2x 30mm tweeters + 2x 40mm mid-range + 1x 60mm woofer + dual passive radiators. The tradeoff: Bass is limited by its 45Hz specification.
Buy the B&O Beolit 20, since the Harman Kardon Go + Play 2 is discontinued and only worth hunting down used.
Water resistance is not close: the B&O Beolit 20 is rated at IPX4 (splashing), well ahead of the Harman Kardon Go + Play 2 at no water resistance.
