Short answer: the MoFi SourcePoint 10. It ranks #27 of 222 bookshelf speakers by sound quality (rated 4.4/5); the Mission LX-3 MKII ranks #138 (rated 3.6/5).
The MoFi SourcePoint 10 is the better-sounding, deeper-bass option. A large bookshelf speaker with a 10 inch concentric driver that acts like a point source, with a huge soundstage and strong, clean dynamics. Its bass reaches about 56Hz before falling 3dB, against 67.4Hz for the Mission LX-3 MKII. The tradeoff: Like virtually all coincident designs, sounds notably bright pointed directly on-axis due to a deliberate treble lift (meant to compensate for the 28mm tweeter’s earlier beaming versus a typical 25mm/1” tweeter) combined with a diffraction dip/peak from the waveguide edge; needs about 15° of toe-out to sound neutral, and even then benefits from an extra 1-2dB of treble EQ.
The case for the Mission LX-3 MKII: 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.
