Good news Tony - Try covering up both the tweeters while playing and see if you notice a difference in the brilliance of the sound. Also, it might be useful to check the setting of your graphic equaliser to make sure that it isn't set up with high frequency roll off.
Due to the natural fall off in our ear's high frequency response as we get older, I have my KN7000 equaliser set up to boost the higher frequencies a little.
