here is a 5.1.4 setup listed on the Klipsch Speakers site. interestingly enough, the front L&R towers have built-in ATMOS modules on the top down inside the speaker, but, the system also includes 2 ceiling mounting speakers for the rear heights. I wonder why didn't they just go with 4 ceiling mounted speakers? in any case, not the surround speaker driver configuration shown. this is offered directly from Klipsch.
