oris 150 sound

i have a question regarding your experiences , in last 5 years i have tried different speaker type including two ways , multi ways (bass reflex) and open baffle types, now i mainly listen to back loaded horn fostex based speaker and i like its coherency and musicality(having no cross=musicality .reallity ), research in forums says oris 150 is a very very good sound ,and even best horn for full rangers. is this front loaded horn significantly better than back loaded ones and is it as coherent and enjoyable? or is it a whole new experience regarding micro dynamics and pretense..??, i wanted to buy a pair with tang bang drivers thanks
