Jacques, I'm sure that the sound you're experiencing with that setup is excellent indeed. Although you "welcome critics" about the only comment I can make(besides indicating amusement at the "Max SPL" and "Total power" specs)is to wonder if you did try the PC12+ directly in the left(or right)corner, which often is the best location for a single sub except in a square room.

Enjoy the music, not the equipment.
