Short answer: the MoFi SourcePoint 10, for its Andrew Jones-designed concentric driver, rated best-in-class for sound power and early-reflections directivity. Its catch is a deliberate treble lift that makes it notably bright pointed directly on-axis, like virtually all coincident designs. The B6.2 is reasonably flat with even horizontal directivity, but a resonant peak around 700Hz and a directivity error around 3.3kHz hold it back.
The MoFi SourcePoint 10 is the better-sounding, deeper-bass pick. 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 64Hz for the ELAC Debut 2.0 B6.2. Watch for: 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 ELAC Debut 2.0 B6.2 if the price is the priority over sound quality, or the MoFi SourcePoint 10 if sound quality is the priority over the price.
