Perhaps forget about delay and align physically? This would require an interesting and large living room, but with a 50hz full sized horn, it is not impossible.

Unquestionably the physical aliment is the way to go at those frequencies. I do not call it physical aliment but the “Real Estate alignment”. Theses 5-8 feet of HF delay are still are not big deal and are manageable…. BTW, and this is very important, one of the sides of my idea to mount the upperbass horn to seiling is to overcome the parasitic HF reflections from the mouth of the large horn. When you place the MF-HF deep into the room then the horizontal footprint of the lower-upperbass horn’s mouth become too prominent and it completely screw imaging for the MF.  However, If you mount that lower-upperbass horn to seiling then the mouth opens up at the location where there is nothing going on anyhow. The upper-upperbass horn might be fairly small (manageable 30-40”) and this upper-upperbass will acoustically couple the lower-upperbass to ground.
