M-Audio Fast Track Pro - Nothing above 13kHz?

[d.bop]

I had to sell my FirePod a little over a month ago to fix my car so I put a M-Audio Fast Track Pro on an in-store credit card to get by for now.

I've been noticing that there isn't much of anything above 13kHz. I manually swept with a tone generator and things really start to drop at about 13.5.

I found this, which seems to prove that this isn't just a problem with mine, but the chart is just too small to really read it. Haha at first I thought my hearing was already starting to go!

So I guess my question is...is this ok? Am I losing much in/above that range?

Thanks!

...bueller?


I'm guessing it's not too much of a big deal. Things still sound great. My guess is that I'll be missing out on some airy frequencies that are more "felt" than heard anyway.


But I would like to know your opinions on this
