Rodney,
Can you post some pictures?
Imaging describes the extent to which an environment reproduces the timbre and location of the individual instruments accurately and realistically. In an environment with superior imaging, you should be able to close your eyes and envision where the instruments were positioned on stage, from one side to the other.
The soundstage refers to your sense of width, depth and height when you listen to music — just as you would sense the placement of different instruments in a live concert setting. Individual vocal and instrumental "images" make up your environment's soundstage.
Note in the above I used the word "environment" as opposed to "system". The environment is your music system plus everything around it. Your room and its contents make a big difference to the sound.
And I agree with everyone else. Make an equilateral triangle between you and the speakers and aim the tweeters somewhere between a foot in front of you to a foot behind you. And try to keep them a couple of feet away from the front wall and as far away from the sides as possible (but never equal to the distance from the back wall).
