I have never heard of either speaker craft or proficient. If someone gives them a bad review, that is enought to scare me away. Most people only post good reviews as it makes them feel they have made a positive choice.
I have not heard the Energy, but based on their reputation for good loudspeakers, would probably say that it is worth a shot. If dialog is your main concern, the Zvox is probably a decent choice. I played with a couple of Zvox models about three or four years ago and was not crazy about either. However, I was looking for a full range sound for movies and music. I believe for dialog and basic TV that either should be more than sufficient for your needs.
