Short answer: the Radiant Acoustics Clarity 6.2. It ranks #28 of 222 bookshelf speakers by sound quality (rated 4.4/5); the Mission LX-3 MKII ranks #138 (rated 3.6/5).
The Radiant Acoustics Clarity 6.2 is the more accurate, deeper-bass choice. A Purifi driver bookshelf speaker with an AMT tweeter, rigid cabinet, non-fatiguing sound, and precise, well focused imaging. Its measured preference score, a predictor of how neutral it sounds, is 5.97 against 4.17 for the Mission LX-3 MKII. Its bass reaches about 55Hz before falling 3dB, against 67.4Hz for the Mission LX-3 MKII. The tradeoff: Needs a fairly specific setup to sound its best: about 15-20° of toe-out (per the manufacturer’s own recommendation) and roughly 2 feet from the rear wall; pointed straight on-axis, the treble reads as noticeably elevated.
What the Mission LX-3 MKII does well: Large affordable standmount speakers with a 6.5 inch woofer, useful bass and easy to drive sensitivity. The tradeoff: On-axis smoothness of 0.217 and predicted in-room smoothness of 0.344 reveal clear response unevenness, with a -0.46dB-per-octave downward tilt.
