Zu Essence + Sub vs Zu Definition MK2?

Understood, I realize the Def. 2 is another level all together, I am looking to eliminate my center channel and go 4.1 for HT and improve my 2 channel. Will the Essence be sufficient for a 4.1 set up with my Klipsch sub and surrounds for HT? 2 channel is my primary concern but I want to make sure that the Essence has a wide enough sweet spot for a phantom center set up.

Mac-7,
Have you tried a phantom center w/ your current set-up?

Yes, and i am somewhat happy with it, i was hoping the Essence would give a wider sweet spot.

Anyone using the Druid or Essence in a 4.1 or phantom center set up?

Essence is wider dispersion, and will give you a better phantom center. Also give you more wall reflections btw.
