All I can tell you is what I hear & the 2 EP500's stacked on top of each other shakes the freaking room like I have never felt/heard..:)

And yes, I used to have them in separate front corners. I don't know if it's phase or what, but with them stacked in one corner, it's way better for "my room" of course...
