Short answer: the Minirig 4 with subwoofer. It ranks #5 of 115 large speakers by sound quality, rated 4.6/5, at $290. The Marshall Kilburn II ranks #43, rated 3.8/5, at $219, $71 cheaper, not enough of a saving to outweigh the sound-quality gap.
Why pick the Marshall Kilburn II: A rugged Marshall styled stereo speaker with a leather handle, quick charging and a sound that suits rock. It plays in stereo from a single unit, unlike the Minirig 4 with subwoofer. Watch for: Boosted upper bass, not very detailed, not as deep bass as competitors, upper mids peak.
The Minirig 4 with subwoofer is the better-sounding, longer-running pick. A compact speaker and wireless subwoofer pair with some of the most balanced sound available, a long battery and deep, impactful bass. It is rated for 30 hours of battery against 20 for the Marshall Kilburn II. At 3.2 lbs (1.44 kg) it weighs much less than the Marshall Kilburn II at 5.5 lbs (2.49 kg). It is rated Splash resistant against IPX2 for the Marshall Kilburn II. The tradeoff: Not stereo, app is buggy.
Buy the Minirig 4 with subwoofer. It is rated higher for sound quality, and saving $71 with the Marshall Kilburn II does not make up for the sound-quality gap.
