Short answer: the KEF Q Concerto Meta if sound quality matters most, the XTZ Spirit 4 if price matters most. The KEF Q Concerto Meta ranks #11 of 130 bookshelf speakers at $1399.99. The XTZ Spirit 4 ranks #92 at $477, $922.99 cheaper.
What the KEF Q Concerto Meta offers: Really good in-room neutrality with consistent horizontal directivity from seat to seat. Directivity holds remarkably steady from lower treble into upper treble, where many similarly-priced speakers narrow sharply as frequency rises - one of the reviewer’s top 10 picks under $1,500. Watch for: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment. Needs to be pointed closer to on-axis rather than heavily toed out - combined with its rolled-off, shelved-down top end, too much toe-out makes it sound noticeably dark.
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 KEF Q Concerto Meta when sound quality outweighs the price for you, and the XTZ Spirit 4 when the price outweighs sound quality instead.
