Short answer: the AsciLab F6Bs. It ranks #20 of 222 bookshelf speakers by sound quality (rated 4.5/5); the MoFi SourcePoint 10 ranks #27 (rated 4.4/5).
The AsciLab F6Bs is the more accurate option. A slim, sealed bookshelf speaker that mounts flat on a wall bracket, with accurate sound and wide, even dispersion for a great price. Its measured preference score, a predictor of how neutral it sounds, is 5.24 against 4.16 for the MoFi SourcePoint 10. The catch: AsciLab’s own site shows the F6Bs sold out, though it remains in stock through resellers like Audiophonics and Tested Audio.
The MoFi SourcePoint 10 is the deeper-bass choice. 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 82Hz for the AsciLab F6Bs. 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.
Buy the AsciLab F6Bs. It is rated higher for sound quality than the MoFi SourcePoint 10.
