First, don't worry so much about the impedance rating of loudspeakers.

And second, the setup routines in surround processors allow you to "trim" the individual volume levels for each channel. In fact, most modern receivers do this for you automatically with the use of an included microphone. Once the channel trims are set, the main volume will adjust all the speakers equally, keeping them at the same level.
