Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Minirig 4 with subwoofer ranks #5 of 120 large speakers by sound quality at $290; the W-King X20 ranks #43 of 113 boombox speakers by sound quality at $229.99.
The Minirig 4 with subwoofer is the lighter pick. A compact speaker and wireless subwoofer pair with some of the most balanced sound available, a long battery and deep, impactful bass. At 3.2 lbs (1.44 kg) it weighs much less than the W-King X20 at 15.9 lbs (7.2 kg). The catch: Not stereo, app is buggy.
The W-King X20 is the tougher option. A loud stereo party speaker with a large subwoofer, a 24 hour battery with power bank, and water resistance. It is rated IPX6 against Splash resistant for the Minirig 4 with subwoofer. It plays in stereo from a single unit, unlike the Minirig 4 with subwoofer. The catch: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.
Buy the Minirig 4 with subwoofer ($290) for a large speaker; the W-King X20 ($229.99) suits a boombox speaker instead.
