Short answer: the MoFi SourcePoint 8 on measured sound quality, the Emotiva Airmotiv XB2 on price. The MoFi SourcePoint 8 ranks #17 of 222 bookshelf speakers, rated 4.5/5, at $2,594. The Emotiva Airmotiv XB2 ranks #48, rated 4.2/5, at $549, $2,045 cheaper.
The Emotiva Airmotiv XB2 is the more accurate option. A great value bookshelf speaker with neutral sound, an AMT ribbon tweeter, and decent bass for its size. Its measured preference score, a predictor of how neutral it sounds, is 5.65 against 5.15 for the MoFi SourcePoint 8. The catch: Slight recessed upper-midrange around 2kHz from the tweeter-to-woofer handoff.
The MoFi SourcePoint 8 is the deeper-bass choice. A bookshelf speaker with an 8 inch concentric driver, neutral sound, excellent imaging, and wide dispersion that forgives placement. Its bass reaches about 52Hz before falling 3dB, against 62Hz for the Emotiva Airmotiv XB2. Watch for: Like other coincident designs, produces diffraction dips around 4kHz and 7kHz when pointed directly on-axis; needs about 10-15° of toe-out to smooth those out.
Buy the Emotiva Airmotiv XB2 when the price outweighs sound quality for you, and the MoFi SourcePoint 8 when sound quality outweighs the price instead.
