Short answer: the MoFi SourcePoint 8. It ranks #17 of 222 bookshelf speakers by sound quality (rated 4.5/5); the Mission LX-3 MKII ranks #138 (rated 3.6/5).
The MoFi SourcePoint 8 is the more accurate, deeper-bass choice. A bookshelf speaker with an 8 inch concentric driver, neutral sound, excellent imaging, and wide dispersion that forgives placement. Its measured preference score, a predictor of how neutral it sounds, is 5.15 against 4.17 for the Mission LX-3 MKII. Its bass reaches about 52Hz before falling 3dB, against 67.4Hz for the Mission LX-3 MKII. Watch for: Like other coincident designs, produces diffraction dips around 4kHz and 7kHz when pointed directly on-axis; needs about 10-15° of toe-out to smooth those out.
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.
