Yes, at the very least, the Rocket cabinets are made in China (PRC) -- probably, the crossover and the final assembly are also done in PRC. The silk tweeter driver is the Vifa, made in Denmark; I am not 100% sure about their mid-woofer but I seem to remember that it is a China-made unit.
I understand that the Axiom cabinets and final assembly are all done in their Muskoka, Ontario facility; the drivers are OEM'ed in China according to Ian's exact specs (Amie, please correct me if I am wrong).
But IMO, where they are made is much less relevant than one fundamental difference between the two brands: According to my understanding, the entire Axiom line, including its drivers/cabinets/crossovers, have been all designed and voiced essentially by one design engineer, Ian Colquhoun, for over 20 years. Thus, the brand has its own definitive style, in its engineering and in its sound. The Onyx brand does not have the same kind of history or single-mindedness to it -- through its very short history, they have already produced vastly different-sounding speakers for whatever reasons; honestly, I have absolutely no idea what type of sound their next speakers will be voiced with... In other words, the chief of Axiom is an engineer; the chief of Onyx is a marketer.
If you have a lot to share with Ian with respect to sonic taste, you are going to love the Axioms; if you don't, you won't.
