I have never heard Jubalees but have a lot of experience with K horns. They do not image well as the drivers are not time aligned and the mid bass is colored which is euphoric for some people. It would be very interesting to digitally tri amp them and get rid of the group delays.
Indeed, that would bring out more of their potential.
I am guessing that the colored mid bass is due to the large, complicated enclosure. Large panels resonate as a function of size as related to panel thickness, the ratio. Think stringed musical instrument.
Relatively large they may be they’re actually too small as a bass to lower midrange horn (corner placement by virtue of extending the horn helps make it act as a horn lower down), which is only exacerbated by several horn path bends up to 180 degrees. Some compensation can be attempted here with a higher compression rate, i.e.: a smaller slot area in front of the woofer to aid upper range extension, but this in turn can create new issues related to upper bass irregularities and colorations due to horn path constriction and air velocity. Cabinet resonances are likely part of the problem as well, but I’d wager they’re really not at the core of the issues mentioned.
