My noob takeaway even if the speakers would work at longer distance with sub the manufacturer actually optimised this for a shorter distance situation and they themselves would probably suggest something else like 310 or 420 depending on distance.
So even they are good there are designs more optimal for longer distances ? I could not say which ones , we have this tread littered with speaker experts , they probably tell us
So then the directivity kink may be inconsequential for the intended use case of a relatively short listening distance ? My guess ?
What’s cool with good pro speakers is that there seems to bee the “same” sound quality the difference is just scale aka your listening distance + you may need a sub for full range
