What Peter said.
Also if you compare the way the Energy is wall mounted to the T bracket mounted QS8 you'll see that the weight is more evenly distributed with the QS8 over a much wider area. With the four mounting points of the Energy all the weight of the speaker will be in that centered area as opposed to the wider area of the QS8.
Whenever I wall mounted our QS8s using the supplied T brackets I actually ordered some recessed speaker binding plates from Parts Express so that there would be sufficient room for banana plugs but ended up connecting the bare wire to the binding post on the speakers, I also used the appropriate sized EZ Anchors for the T brackets and believe a person could actually hang from the speakers ... but I ain't going to try it.
