Short answer: the GR-Research NX-Bravo for wide vertical dispersion, the KEF Q Concerto Meta for in-room neutrality. The NX-Bravo’s tonal matching holds from about 50° above the tweeter axis to 20° below, though on-axis it carries a deliberate ~5dB high-frequency bump. The Q Concerto Meta is really good in room with consistent horizontal directivity, but its radiation measures about ±50°, narrower than the reviewer’s preferred ±60°.
Buy the KEF Q Concerto Meta. It is rated higher for sound quality than the GR-Research NX-Bravo and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
