That high of a frequency is only for harmonics. Most people don't hear over 20,000hz. I don't hear much over 13,000hz. Some feel that harmonics play an important role in the sound of music and to some extent that is true. I'm just not sure if harmonics over 20,000hz really make a difference since I can't hear that high :-). You're young so you may be able to hear a difference. Enjoy it while you can cause as you age your hearing goes. Work in a noisy environment and it goes even quicker. So to answer your question, I probably couldn't tell the difference in the super tweeter speaker whereas you may very well be able too.
