I am planning a re-do of a speaker design I did back in 1979 with (16) 5 1/4" drivers loaded into hexagonal prism cabinets with 4 tweeters scattered about the various faces. My choice of cabinet style will dictate driver choice. The original design was sealed, but I'm also contemplating a slot loaded design with holes in top and bottom of the prisms with a plate on top (and perhaps the bottom as well) as an omnidirectional slot load(s). How would one handle this kind of construction in the usual box simulation program?
