Short answer: the Emotiva Airmotiv XB2 if sound quality matters most, the XTZ Spirit 4 if price matters most. The Emotiva Airmotiv XB2 ranks #40 of 130 bookshelf speakers at $549. The XTZ Spirit 4 ranks #92 at $477, $72 cheaper.
What the Emotiva Airmotiv XB2 offers: Very neutral, linear frequency response at the recommended toe-out angle, with better directivity than the similarly-priced ELAC DB63. Decent bass extension for a bookshelf (F3 at 62Hz). AMT folded-ribbon tweeter with a rotating waveguide for placement flexibility. Great value - rated a top-three performer for the money by Erin’s Audio Corner. Watch for: Slight recessed upper-midrange around 2kHz from the tweeter-to-woofer handoff. Sounds noticeably bright pointed directly at the listener - needs toeing out 10-20 degrees, crossfiring behind the head, for the most linear result. Elevated multi-tone distortion at higher output leads to some grainy, compressed mids when pushed. Irregular compression deviations affect dynamics at higher volume. Needs a subwoofer for real bass authority.
What the XTZ Spirit 4 offers: Substantial 6.5-inch stand-mount with a waveguided dome tweeter, adjustable treble level and port tuning. Spinorama predicts 44Hz in-room extension, broad roughly +/-60-degree horizontal coverage and a 5.39 preference score with a subwoofer. Watch for: The third-party measurement is low confidence. On-axis smoothness is only 0.248, directivity-index consistency is middling at 3.21, and the mildly downward -0.29dB/octave tonal slope contributes to a modest 3.27 raw preference score.
Buy the Emotiva Airmotiv XB2 if sound quality is the priority over the price, or the XTZ Spirit 4 if the price is the priority over sound quality.
