Klipschorn Corner Placement ?

[Idontknow]

I’ve noticed some listeners who have acoustic treatment in the corners alongside and behind these speakers in some videos. Isn’t this defeating the purpose of using the corner as an extension of the K-horn? Why do some listeners do this while others don’t? 
 

Thank you,

Corner treatment is generally LF in nature... yes, that is in direct conflict with the usage of the corner to enhance the LF of the Klipschorn.

I had reservations about putting up a Khorn for over 30 years. I thought there was only one correct positioning in the corners. And if it booms or resonates badly in this way, I have no alternative for positioning it in the room. This spring I took the plunge for the first time because I thought now or never.

I have to say that, at least in my room, the Khorn makes the least drone of all the speakers I've had so far, almost no drone like my little BBC speakers can do as well. Everything sounds clear and differentiated, right down to the bass. Maybe I was just lucky. At least it seems that the Khorn “uses” the corners in a completely different way than when the corners are empty and then perhaps cause a boom when using conventional speaker setups. Maybe, and this is my amateur hypothesis, the cabinet of the Khorn itself prevents the boom because it fills the corners. In any case, everything is very positive.

I have my Khorns in the corners with LF treatment above them in the corner with a triangular shape works great,

no issues just clean as could be...

Ive found improperly implemented corner absorption can kill a rooms positive properties.
