I have recently purchased several new Klipsch speakers, a pair of bluetooth R15PM powered monitors, a pair of (non-powered, non-bluetooth) R28F floor towers and a 10" R10SW subwoofer (that I have connected to the powered monitors) and I also have two indepedent Crown stereo power amps (XLS1500's) I can use. How can I combine all of these Klipsch speakers together into one system? Do I need to purchase the Gate or the Powergate? What I typically do is play Spotify from my phone through the powered monitors and sub and in another room I use one of the Crown amps hooked up to my computer to listen to Spotify through my big towers.
