Hilde45,
A quick and dirty test to do and report back. Sounds really stupid and crude, no cost, but it works as another method for process of elimination and targeting some things with a particular speaker to get some ideas. Quick to try.
1. Put grilles on speakers if speakers came with them and note any change - at all? Did any etch, glare, or other disappear at all - report back.
Remove grilles - if they were on...now for the crude part :)
2. Cover the tweeter with one layer of thin paper towel, stick on lightly with a small piece of painters blue tape, and report back. Any etch or glare disappear?
3. Next cover the midrange with thin layer of paper towel, barely tape on with painters tape, be sure to not double-up on it, report back.
4. Do 2,3 together, both tweet and mid, report back. Does it become fuller and more musical with 2,3 together?
Just a simple test to get ideas with an overly bright tweeter/mid layout before trying any mods internally, or padding down either. I agree with prior assessments of exaggerated tweets/mids on some speakers, and the room can make it better or worse.
You can add/remove the pt back and forth as you are sitting there listening. Extrapolate from here,
Oh, note this and for AMTs, here is what Legacy does - trim buttons +/- 2db look here, old method from early days of AMTs because rooms and gear varies greatly.
