That's right, Slim. No need for an external amp. The digital x-over and amp are built into the speaker. The signal is sent via Axiom Air from a small base station connected to your pre amp.

You'll also be able to buy the existing LFRs with the passive x-over.

Maybe you'll even be able to specify the amp power you want built-in?
