Short answer: the KEF LS60. It ranks #2 of 15 powered floorstanding speakers by sound quality (rated 4.8/5) at $5,999.99 and is still sold new; the B&O Beolab20 ranks #12 (rated 3.5/5) and is discontinued, so it is only an option used.
The KEF LS60 is the better-sounding pick. Wireless floorstanding speakers with extremely accurate sound and bass deep enough to skip a subwoofer. The tradeoff: A diffraction dip around 9kHz can soften cymbal shimmer when aimed directly at the listener; 10-20 degrees of toe-out helps.
What the B&O Beolab20 does well: Active floorstanding speakers with bass deep enough to skip a subwoofer and placement settings for free, wall or corner use. Watch for: A 4.88 ideal-subwoofer preference score shows that deep bass does not compensate for the tonal flaws.
Buy the KEF LS60. It is rated higher for sound quality; the B&O Beolab20 is no longer sold new.
