Short answer: the MoFi SourcePoint 10, whose Andrew Jones-designed concentric driver the reviewer rates best-in-class for sound power and early-reflections directivity. The price of that coincident geometry is a deliberate treble lift, so it sounds notably bright pointed directly on-axis, as with virtually all coincident designs. The ELAC Debut 3.0 DB63’s weakness is more mundane: a 1.5dB dip from 300-600Hz that reduces vocal warmth.
The MoFi SourcePoint 10 is the 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 76Hz for the ELAC Debut 3.0 DB63. 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 ELAC Debut 3.0 DB63 if the price is the priority over sound quality, or the MoFi SourcePoint 10 if sound quality is the priority over the price.
