Short answer: the AsciLab C6B on value, the MoFi SourcePoint 10 for directivity. The Andrew Jones-designed SourcePoint 10 concentric driver delivers best-in-class sound power and early-reflections directivity, but like virtually all coincident designs it sounds notably bright pointed directly on-axis due to a deliberate treble lift. At $1,145 versus $3,795, the C6B is far cheaper, and its bass rolls off around 50Hz in-room.
Why pick the MoFi SourcePoint 10: A large bookshelf speaker with a 10 inch concentric driver that acts like a point source, with a huge soundstage and strong, clean dynamics. The catch: 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 C6B. It is rated higher for sound quality than the MoFi SourcePoint 10 and costs less, which makes it the one to get unless you need something the other one does better.
