Short answer: the Marshall Kilburn II. It ranks #39 of 82 large speakers by sound quality (rated 3.8/5); the Orange Box ranks #71 (rated 2.5/5).
What the Marshall Kilburn II does well: 20W Class D amp + dual 8W tweeters. Watch for: Boosted upper bass, not very detailed, not as deep bass as competitors, upper mids peak.
Why pick the Orange Box: 50W RMS output power, IPX7 waterproof, 15-hour battery life, guitar amp-inspired vintage design, 102mm woofer with dual tweeters, Bluetooth 5.0, AUX input, TWS pairing, built-in microphone, solid wood construction. The tradeoff: Pathetic bass extension, port noise, hollow sounding.
Buy the Marshall Kilburn II. It is rated higher for sound quality than the Orange Box.
