The 2 subs were in a corner of the room, we did have the Hsu out in the middle between the M80s briefly at the beginning and it was still way stronger than the EP400. Just to be somewhat more fair we moved the Hsu to the same area as the EP400.
No optimizing, for either sub as my area is limited in its positions and I was more interested in how they would sound in the desired position.
Calibration was set on both with pink noise to the same levels as the mains. This was just a quick off the cuff comparison, but I highly doubt in my area, any movement would have had much effect on the Hsu.
And no I didn't take any pics, DOH! They would have been quite funny to see the Hsu towering over the EP400, much like the EP600 is to the EP500.
