Well, I've been spending the day watching scenes from a variety of Blu-rays: Band of Brothers, WALL·E, Transformers, Iron Man, The Incredible Hulk, and The Dark Knight. I'm definitely feeling a lot more in the bass-heavy scenes. I still haven't done any experimenting with placement of the second subwoofer, so I can only imagine how much more impact I can coax out of it. In any case, based on my experience so far, I am pretty happy with my investment. It doesn't make movie-watching leaps and bounds better than the single EP600, but it is certainly another significant step toward the great home theater I'm trying for.
