Monacor DT-25TI

[tpsorin]

Hello,

I just received a pair of these Monacor tweeters.
I see something strange: inside grille there is a plastic foil in form of a donut.
What is the purpose of these foil?
What I hear, is that changes the sound when hearing from more than 30deg angle. This is something that I don't like.
Any idea how to remove it? the tweeter can not be opened.

Here is the picture:

I know it is hard to see on the picture with some monitors, but it is there.

Hi,

I have the DT-250 which is almost the same, except frontplate/neodymium magnet. I would leave it in place since the DT-25ti has a really nice dispersion without showing any resonances even to 60 degrees...
