Short answer: the Audio First Cadentia 3 for better sound quality, the Emotiva Airmotiv XB2 for the lower price. The Audio First Cadentia 3 ranks #7 of 222 bookshelf speakers, rated 4.7/5, at $7,199. The Emotiva Airmotiv XB2 ranks #49, rated 4.2/5, at $549, $6,650 cheaper.
The Audio First Cadentia 3 is the more accurate, deeper-bass choice. Near-textbook measurements: excellent on-axis linearity, listening window, and directivity, with only minor deviations. Its measured preference score, a predictor of how neutral it sounds, is 7.55 against 5.65 for the Emotiva Airmotiv XB2. Its bass reaches about 43Hz before falling 3dB, against 62Hz for the Emotiva Airmotiv XB2. Watch for: A mild scoop through the upper midrange/lower treble slightly softens the attack of snares, hand claps, and sibilants: fixable with a single-band EQ (2.5kHz, +1dB, Q~1).
The case for the Emotiva Airmotiv XB2: Very neutral, linear frequency response at the recommended toe-out angle, with better directivity than the similarly-priced ELAC Debut 3.0 DB63. Watch for: Slight recessed upper-midrange around 2kHz from the tweeter-to-woofer handoff.
Buy the Audio First Cadentia 3 if sound quality is the priority over the price, or the Emotiva Airmotiv XB2 if the price is the priority over sound quality.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared. The two were measured by different sources, so small differences, especially in the bass, can come from the measurement setup rather than the speakers.
