Julie,
Before you try the EQ, make sure your speakers are not in the corners of the room. and are at least a foot from any wall. If you put them in the corner, or close to a wall, you will get too much bass. Also, they should be up off the floor. Milk cartons work well for this, or you could get speaker stands. It is best if the tweeters are at ear level in your listening position. Get the sound as good as you can before you start using an EQ, and the result will be better.
