IDK if I am sensitive to high frequencies or something, but this has been an issue with every speaker... at low volumes, everything is cool... once I crank the volume, certain high frequencies, like guitars and vocals, hurt my ears. Sometimes it drowns out all other sound, so I will only be hearing this incredibly harsh tone (and my ears hurt). if I turn the volume up, it will be apparent in just about every track. My only solution right now is to lower the volume.
Some tracks that this is really noticeable in: MGMT- Time to Pretend (the start), Counting Crows - Angels of the Silences, Weezer - The angel and the one
So, is there any quick fix for something like this? I tried using an equalizer and lowering the high frequencies, this did not make a difference. I also tried cutting up some wash rags and putting them around the tweeter... I think I am going to go get some felt when I'm at the store next, cause it might have helped a bit.
