Short answer: the Minirig 4 with subwoofer. It ranks #5 of 115 large speakers by sound quality, rated 4.6/5, at $290. The W-King D9 ranks #93, rated 2.5/5, at $89.98, $200.02 cheaper, not enough of a saving to outweigh the sound-quality gap.
The W-King D9 is the longer-running, tougher option. A compact, punchy boombox with a very long rated battery, water resistance, and power bank output for casual outdoor use. It is rated for 40 hours of battery against 30 for the Minirig 4 with subwoofer. 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: Treble rolls off early, limiting air and fine detail, while owner reports note Bluetooth interference and some noise at maximum speaker volume.
The Minirig 4 with subwoofer is the better-sounding, 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 noticeably less than the W-King D9 at 4.4 lbs (2 kg). It has an adjustable EQ, which the W-King D9 lacks. Watch for: Not stereo, app is buggy.
Buy the Minirig 4 with subwoofer. It is rated higher for sound quality, and the $200.02 you would save on the W-King D9 does not close the gap.
