Khorn room size

I enjoy the sound of my KHorns in a similar size room. However I built false corners for them using 3/4" plywood so I could change the angle of the speakers. Part of the problem in such a small room is the speakers are not far enough apart and the focal point where they are aimed is sometimes only a few feet in front of the speakers. The false corners may allow you to angle them in or out to suit your taste.

I agree the angle can be an issue.
I disconnected the Top Hat (houses the mid and tweeter) from the base (bass) in an attempt to do what you did, change toe-in of all but the bass. Close but no cigar for me.

I have my Khorns in a room 17'X 21'. I've had the speakers for over 20 years in 4 different rooms (all smaller than this) and for the first time things are working well. Any room much smaller than this and it's tough to get them to perform at their best. I also have Lascalas and they seem to work a bit better than the Khorns in a smaller room.
