two points
1) with stu tyler and proacs, one mainly needs to understand that bigger models are for bigger rooms, more bass output, more absolute spl capability - so the trick is to get the RIGHT speaker for your room, not the highest speaker in line that you can afford - stu’s higher dual woofer models will absolutely overload a room that is too small for them
2) from his marketing verbiage, it seems he is trying for an even higher level of transparency in the k series... having proacs since the 1990’s i would never say that his regular speakers, the curren td series etc etc are artificially warm or with any extra romantic coloration -- in fact i would say that among the british boxed speaker makers, proacs already among the most ’see through’ in sound character (equalled only by atc perhaps) ... so i am curious to know how far stuart is going with the k series...
