I am finishing my basement and last black Friday I purchased a pair of KF-28 tower speakers. I will be using a 12" Polk audio sub that I also already own. I need one in-ceiling center, and two in-ceiling speakers for surround. The area is about 12' x 24. The center speaker I am looking at getting is the Klipsch CDT 2800-C II The surrounds I am looking at getting are the Klipsch R-1800-C I'm looking for a 5.1 receiver that will drive this well. It would be nice if it had the ability to connect to IOS devices. What would be a good option? Is my configuration decent? Thanks so much in advance.
