Is Room treatment different for Horn Speakers?

Yes... didn't have them long enough to tweak extensively, but they functioned better 12"- 15" into the room. So far the Cornwalls sound pretty good close to the wall.

I have a lot more listening to do before I go crazy. I think this is the 10th day of ownership.

I am remounting all the absorption panels with cleats and installing a continuous cleat across the back wall, so I can change them easily.

My room treatment is predominately GIK Bass absorption. Been wondering if some dispersion would be in order for the back wall.

The last few days these Speakers have really blossomed. Bass right now is good. I hear some what I call "frequency specific resonance",.. I was wondering if a little dispersion would help. I understand other Cornwall owners mod their speaker horns with Dynamat, but I don't want to go there just yet.

russ69- and that's why I bought them!😊.. I wanted something that didn't have to be set so forward into the room.

Duke, atmosphere, rego, actually everyone above, thanks for the comments. I have the speakers as far apart as I can get them... I will try to toe them in so they cross in front of me. These speakers do sound good when I set at my desk in the corner. I am really enjoying these Cornwalls, I believe with some tweaking (acoustic and otherwise) these could be very very good.
