Short answer: the MoFi SourcePoint 8 on value, the SourcePoint 10 for best-in-class directivity. The 10’s concentric driver delivers best-in-class sound power and early-reflections directivity, but it sounds notably bright on-axis from a deliberate treble lift and costs $1,201 more. The 8 pairs an 8” twin-drive concentric driver with a 1.25” soft dome in a diffraction-reducing baffle, yet it shows diffraction dips around 4kHz and 7kHz.
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 MoFi SourcePoint 8. It is rated higher for sound quality than the MoFi SourcePoint 10 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
