Short answer: the Minirig 4. Both are rated 4.3/5 for sound quality (#7 and #11 of 177 medium speakers), and the Minirig 4 costs $229.95 against $395 for the B&O Beosound A1 2nd gen, and with sound quality even, the cheaper one is the better buy.
The Minirig 4 is the louder, longer-running pick. A small, long lasting speaker that gets loud and can add a matching subwoofer, with a 30 hour battery. Alan Ross Reviews measured it at 106dB at full volume, against 93dB for the B&O Beosound A1 2nd gen. It is rated for 30 hours of battery against 18 for the B&O Beosound A1 2nd gen. It keeps a wired aux input, which the B&O Beosound A1 2nd gen lacks. The catch: Calls itself splash resistant and has no official water rating.
The B&O Beosound A1 2nd gen is the tougher pick. A premium waterproof puck speaker with balanced sound, a built in strap, and a long battery for travel. It is rated IP67 against Splash resistant for the Minirig 4. It supports aptX Adaptive Bluetooth, which the Minirig 4 lacks.
Buy the Minirig 4. Both are rated the same for sound quality, and it costs $165.05 less than the B&O Beosound A1 2nd gen.
