Jay L has posted official specs on post #60 (page 3).

Here are some initial specs I gathered for the new Reference Premiere Dolby Atmos Enabled speakers from Klipsch.
Current models include the all-in-one RP-280FA Floor Standing Tower with integrated Dolby Atmos speaker.
And, the separate upward firing RP-140SA add-on module, Klipsch is calling this an "Elevation Speaker.
The spec sheet I created below, is from available info online, (so nothing presented is officially from Klipsch),
but the provided specs below should be a fair representation of what can be expected. There is also an
RP-450CA Center channel... but at the moment, I'm not sure how that fits specifically into the Atmos configuration.
Here are the pics:
