I only have one EP500. My other sub is a Buttkicker which goes way lower than the EP800, 5Hz, with authority. One of my Buttkicker demo scenes is the opening to Star Wars III and your right I can’t wait till it comes out on Blu-ray. Already preordered mine.
I tried multiple subwoofers I borrowed from Sean but found that in my oddly shaped room that I couldn’t find any multi-sub configuration that didn’t perform worse than a single sub in the best location. So now I EQ instead thanks to Charles.
