Piedpiper is correct. Kuzma's new sourcing arrangement is with ZYX, effective early this year. Before that they did rebadge Shelters, as Rauliruegas said.
Kuzma does not have access to the UNIverse or Atmos, so whatever models they offer are presumably comparable to the Airy 3 or below.
Mapping of Kuzma model to ZYX model is something neither company will discuss, for obvious reasons. The Airy 3 and Airy 2 specs read the same, so judging by price does seem like the only way, short of buying one of each and doing an A/B of course.
