I was at a local dealer to pickup a stand for my Persona C and he had the founder series all over the store. He played me a quick demo of the 120h with ARC. All I have to say is that the bass was insane. It was tight, accurate, and shook the 2nd floor demo room. I know there might not be a lot of fans for having powered subs in their speakers, but I am really curious how these these measure. They seem to have a much more laid back than the paradigms I am used to. My demo was very brief, but I was impressed.
