I’d nominate the latest iteration of the GR-Research NX-Oticas along with the matching open baffle sub.
This is a kit speaker with cost-no object components. My brother-in-law (who reads schematics) helped me build it and it’s a screaming success. Best SQ I’ve ever heard in any audio store or any CES Hi-End demo room.
I find they sound best painted Ferrari Red.
See the pic in Virtual System section. Sorry I couldn't figure out how to include the link.
