Short answer: the XTZ Spirit 4. Both are rated 3.4/5 for sound quality (#159 and #156 of 222 bookshelf speakers), and the XTZ Spirit 4 costs $477 against $764.97 for the KEF Q3 Meta, so with nothing between them on sound quality, price settles it.
The case for the KEF Q3 Meta: Coaxial bookshelf speakers with very wide dispersion, punchy kick drums and bass tuning that works close to a wall. The catch: Not well suited to high-output use: compression and strain in the 1-2kHz region emerge above about 90dB at 10 feet, so a high-output home theater setup isn’t the best application.
What the XTZ Spirit 4 does well: Stand-mount speakers with a waveguide tweeter, adjustable treble and port tuning, wide coverage and fairly deep bass. The catch: The third-party measurement is low confidence.
Buy the XTZ Spirit 4. Both are rated the same for sound quality, and it costs $287.97 less than the KEF Q3 Meta.
