Short answer: the W-King X20 for output, battery and waterproofing, the Minirig 2 with subwoofer for balance. The X20 puts out 200W RMS (330W peak) and 112dB max volume with a 24-hour battery plus power bank and IPX6, though its response rises with upper treble rolled off and peaks at 700Hz and 1.2kHz. The very balanced Minirig costs $30.01 more and is not stereo with a buggy app.
One note: the Minirig 2 with subwoofer is no longer sold new, but at #7 of 120 large speakers by sound quality it still outranks most current models, so used is worth considering. The Minirig 2 with subwoofer’s replacement, the Minirig 4 with subwoofer, is rated 4.6/5 at $290.
Buy the Minirig 2 with subwoofer ($260) for a large speaker; the W-King X20 ($229.99) suits a boombox speaker instead.
There is a real battery-life gap here: the Minirig 2 with subwoofer is rated for 40 hours, the W-King X20 only 24 hours.
