Short answer: the Marshall Kilburn II. It ranks #42 of 120 large speakers by sound quality, rated 3.8/5, at $219; the Orange Box ranks #99, rated 2.5/5, and costs $359, which makes this an easy call rather than a real tradeoff.
The Marshall Kilburn II is the better-sounding, longer-running choice. A rugged Marshall styled stereo speaker with a leather handle, quick charging and a sound that suits rock. It is rated for 20 hours of battery against 15 for the Orange Box. Watch for: Boosted upper bass, not very detailed, not as deep bass as competitors, upper mids peak.
The Orange Box is the tougher option. A guitar amp styled speaker with a solid wood cabinet, waterproofing, and stereo pairing for a striking retro look. It is rated IPX7 against IPX2 for the Marshall Kilburn II. The catch: Pathetic bass extension, port noise, hollow sounding.
Buy the Marshall Kilburn II. It is rated higher for sound quality than the Orange Box and costs less, which makes it the one to get unless you need something the other one does better.
