Short answer: the Marshall Kilburn II. It ranks #42 of 120 large speakers by sound quality, rated 3.8/5, at $219; the B&O Beosound Level ranks #92, rated 2.8/5, and costs $2,250, so there is little reason to consider the other one.
The Marshall Kilburn II is the better-sounding, lighter choice. A rugged Marshall styled stereo speaker with a leather handle, quick charging and a sound that suits rock. At 5.5 lbs (2.49 kg) it weighs noticeably less than the B&O Beosound Level at 7.3 lbs (3.3 kg). Watch for: Boosted upper bass, not very detailed, not as deep bass as competitors, upper mids peak.
The B&O Beosound Level is the tougher option. A sculptural luxury speaker that works on battery or mains, mounts on a wall, and streams over Wi-Fi with upgradeable modules. It is rated IP54 against IPX2 for the Marshall Kilburn II. Watch for: Not very deep bass, peaks in midrange.
Buy the Marshall Kilburn II. It is rated higher for sound quality than the B&O Beosound Level and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
