If you are worried about Atmos speakers blending with the system, you don't need to. I am a big proponent of matching up the main speakers for Multi-Channel audio and built my system accordingly, with the closest matching Speakers at Main, Center and Surround. Even my rears currently have matching tweeters! But when I add Atmos, I'm going to be using different drivers most likely, though my goal will be to have the voicing still as close as possible, they will be different.
