After my previous experiences with measurements!
I can say that the Geithains are a touch more congested in the mid range than the Kiis ( Kiis were already set up for a dem) there isn’t much in it but there just isn’t the separation some I suppose some might enjoy the homogeneity of the Geithain sound .

cardioid
Bit more about the cardioid: https://www.audiosciencereview.com/forum/index.php?threads/musikelectronic.3423/
Cardioid is accomplished with a small woofer slot (port) in the side of the cabinet?
What if I turn my down-ported subs on their side? Do they become cardioids?
