Add the fact that you don’t need an expensive receiver to run the Edifiers and you can immediately add a Chromecast Audio to make them wirelessly enabled, and the Edifiers shine as a stand alone smart speaker system. Don’t get the Polks unless it is as rear speakers for surround sound, in which case I highly recommend them.
