Well, I think it is horses for courses and the tapped horns are a bit of a different gigi.     I found it is imperative to suffocate the rubbish that is coming out of tapped horns above say 100Hz - mine are sized to work from around 20Hz to 90Hz. Below this there is great bass deep bass to be had - well at least I like it.      The mid bass / upper bass I do not use such a slope. 2nd order on the upper knee of my bass at 330Hz and same for the lower knee of the mid horns. Above that I like 2nd order and then on the upper mids and tweeter 1st order. That is the current set.
 
Ok, the upperbass that you have I think it was something around 125Hz. Regardless what kind profile and size of the horn you have we all know what kind lower knew decay uppperbass has, even in a smallish room it is “large” but  “thin”.  Then you have LF section, the trapped horn that you decided to stop with brick-filter. That reasonably long tail from LF is important in my view. If you have rubbish out of tapped horns above 100Hz then it is problem of tapped horn, not the problem of uppperbass.  The brick-filter shall swing phase super violently in addition to everything else… Anyhow, I would not use any topology that demands 8th order filter. I wonder: at 90Hz the trapped horn makes “good bass”   but at 120Hz it gives rubbish? Are you listening mostly rick-n-roll?

All sorts of music types. Piano, orchestral/choral and church organ feature, as well as electro / and what you might call rock.Could be - lots of problems in audio. The fun is in solving them.
