Grouping a two pair of KEF LSX's

Hi -

I have a question concerning grouping two pairs of KEF LSX’s. I have read the grouping restrictions and a few other threads here. If I’m understanding correctly, the KEF LSX’s will group together as they are the same “type” via Airplay?

Is this correct?

I appreciate the help, thanks

Via airplay probably no issue…sync remains to be seen how long they can manage to be together tho. YMMV
