At this point I prefer soft dome and paper/carbon type drivers and have not been a fan of ceramic drivers, beryllium, diamond or aluminium tweeter
Then you should try to audition ATC or PMC - a 3 inch soft dome midrange with paper/pulp woofer and soft dome tweeter. Mine are soffit mounted so I have an unfair advantage when it comes to the disappearing act (not heard better from any freestanding setup).
MBL's are a great option but I fail to understand how they can possibly prevent/control unwanted resonances on those long flexible lamellas.
