Hi , I recently replaced my poly switches thinking that they were the source of the problem. I was wrong; the tweeters in one of my speakers only work when you apply a little bit of pressure to the crossover in the top left corner. The tweeters seem to let some of the sound through with light pressure and with a little bit more they open up full. I stuck something under neath the bottom right corner to apply forward pressure on it (this seems to work as well). I sat back to have a quick listen to be sure that it was sounding how it should and it was sounding perfect. I tried some different material and all was sounding good until I played a jazz piece with a really dynamic piano player. I noticed that when keys were hit with a higher velocity it caused a distortion sound to come from the tweeters (only in the speaker with the Problem [the piano was not panned] ). Then the tweeters started to cut out again... I am really confused as to what is happening here. Once again the speakers no longer have poly switches.
I hope I described this in a way that makes sense... If anyone has any idea what could be happening here, let me know!
Thanks for your time and Cheers!
