anything wrong with a square mouth on the midbass (or should it it be in a special width/height ratio)? would give me the right height of upper mr when i go 4way....

Klaus, no one would give you a definitive answer to it. A rectangular mouth creates harms in imaging department but with frequency lowering the amplitude of rectangular mouth’s problems is lowering as well. It would be difficult to say belong which frequency the rectangular mouth stops to be a problem as the rectangular imaging problems with dropping of frequencies got offset with benefits of rectangular coupling. The rectangular bass horns better coupling to room boundaries and might get more result in horn imbedding. Read the following thread:

How, pretend that you have 60Hz spherical and rectangular horns but the rectangular, being load with long side to walls, gives you +3dB-4dB. If that 60Hz horn does not shoot up to 2000Hz (and it must not) then would a higher imbedded sensitivity of the rectangular horn overweight the hypothetic imaging problem? It would certainly do for me, not to mention that no one has a luxury to make those experiments and we are talking about pure assumed judgment. I know that if I go for my 50Hz horn then it will be rectangular… BUT … I have to admit that the spherical 50Hz is so maximalistcly-beautiful idea! Still, I admit that rectangular bass horn has many reasons to sound better.
