Short answer: the AsciLab C6B for a conventional presentation, the GR-Research NX-Bravo for flexible vertical dispersion. The NX-Bravo holds tonal matching from about 50° above the tweeter axis to 20° below, though pointed straight on-axis it carries a deliberate ~5dB high-frequency bump meant to offset narrowing dispersion. The C6B is the simpler, cheaper buy at $1,145 versus $1,540, but its bass rolls off around 50Hz in-room.
Buy the AsciLab C6B. It is rated higher for sound quality than the GR-Research NX-Bravo and costs less, which makes it the one to get unless you need something the other one does better.
