Good topic. According to Robert Harley in his book, The Complete Guide to High End Audio:
"Typically, the loudspeaker will be brightest (i.e. have the most treble) when your ears are at the same height as the tweeters or on the tweeter axis. Most tweeters are positioned between 32" and 40" from the floor to coincide with typical listening heights........The degree to which the sound changes with height varies greatly with the loudspeaker. Some models have a broad range over which little change is audible; others can exhibit large tonal changes when you merely straighten your back when listening...."
So in general, your tweeters and your ears should be at the same height. You may need to invest in a chair with a high adjustable seat or perhaps a chair like a bar stool. You may want to check to see if your Ushers fit the category Robert describes where little change is observed when listening height changes (broad range). You could also tilt them in towards you and toe them in as well. Experimentation is a must but also check with Usher to get their recommendations. Did the speakers come with an owner's manual with recommendations?
Let us know how you do. I'm sure many folks would be interested.
