Maximize your tweeter performance
The biggest advantage of component speakers versus 2- or 3-way speakers lies in the ability to mount the tweeter with a more direct path to your ears.

Before you install your tweeters, experiment with different tweeter locations and mounting angles if possible. A little time spent positioning your component tweeters can pay off big with a much more realistic soundstage.
