Midrange/treble harshness at volume

Order a pair of free standing GIK 244 panels for first reflection absorption.  I had the same problem and the 244 panels fixed it instantly.

You might be sensitive to the metal tweeters in that speaker!

Small rooms do have limits.

If my numbers are right you’re getting a lot of cancelation on the bottom and that makes the mids / highs much more forward. I think a bass fix will help. Address the first reflection points behind, over your head, and in front of you on the floor.

The ROOM is the usual, problem. a full 1/3 of SQ, ay..

Room correction an option?

Going kitty corner will help a lot too..

Have fun.

You need to EQ from about 3Khz on out to 20Khz drop it about 6db. It’s not hard to do if you’re using roon. Look at the plots on Stereophile that speaker is to lively and tilts up .

I agree, treat your room. Makes all the difference, and doesn’t have to be ugly, obtrusive, or expensive.

Thanks for all your suggestions, I am going to look into the room treatment options.
I dont have roon, streaming spotify mostly, suggestions for equalization?
