Short answer: the Minirig 4 with subwoofer on measured sound quality, the W-King D9 on price. The Minirig 4 with subwoofer ranks #5 of 78 large speakers at $290. The W-King D9 ranks #66 at $71.24, $218.76 cheaper.
What the W-King D9 offers: A compact 2kg boombox with 60W RMS output, a claimed 106dB maximum level, a measured 47Hz -10dB bass point, IPX6 protection, power-bank output, USB-C charging, aux and microSD playback. Long-term owners praise its loud, punchy character and useful indoor/outdoor voicing for casual outdoor listening. Watch for: Treble rolls off early, limiting air and fine detail, while owner reports note Bluetooth interference and some noise at maximum speaker volume. There is no app or adjustable EQ, and its bass does not reach as deep as larger rivals, so it is better suited to energetic background music than neutral listening.
What the Minirig 4 with subwoofer offers: Very balanced sound. Finally USB-C charging. Deeper, more impactful bass than the old Sub 3. Subwoofer pairs wirelessly and can be placed anywhere in the room for extra bass. Fine-grained tuning via the app - 5-band EQ plus separate bass/treble and subwoofer controls. Sounded more accurate than the JBL Xtreme 5 in a side-by-side comparison, and the whole 2.1 setup is smaller and lighter than it. Watch for: Not stereo, app is buggy. Not easy to carry on the go, no handle and there’s 2 pieces. Calls itself splash resistant but has no official water rating. A bit expensive. Has reliability issues more often than any other speaker. Default out-of-the-box tuning sounds off and needs a custom EQ to sound its best.
Buy the W-King D9 if the price matters more than sound quality. Buy the Minirig 4 with subwoofer if sound quality matters more than the price.
