Short answer: the Minirig 4. It ranks #7 of 177 medium speakers by sound quality, rated 4.3/5, at $229.95. The W-King D8 Mini ranks #135, rated 2.6/5, at $49.99, $179.96 cheaper, which does not close the gap in sound quality.
The Minirig 4 is the better-sounding, deeper-bass option. A small, long lasting speaker that gets loud and can add a matching subwoofer, with a 30 hour battery. Its bass reaches about 56Hz before falling 10dB, against 63Hz for the W-King D8 Mini. Alan Ross Reviews measured it at 106dB at full volume, against 100dB for the W-King D8 Mini. At 1.2 lbs (550 g) it weighs much less than the W-King D8 Mini at 2.8 lbs (1.26 kg). The tradeoff: Calls itself splash resistant and has no official water rating.
The W-King D8 Mini is the tougher choice. An inexpensive water resistant stereo speaker with indoor and outdoor sound modes and a long rated battery. It is rated IPX6 against Splash resistant for the Minirig 4. It plays in stereo from a single unit, unlike the Minirig 4. Watch for: Recessed midrange, harsh treble.
Buy the Minirig 4. It is rated higher for sound quality, and saving $179.96 with the W-King D8 Mini does not make up for the sound-quality gap.
