Front horn, HF response.
 
In a tractrix front horn with a throat area just wider than the driver, why does hornresp show the HF rolling off continuously? Shouldn't the driver become a direct radiator at HF so the response plateaux at the rated sensitivity?

By default, Hornresp only shows the horn's output, but in the SPL response window you can choose to sum it with the driver's pistonic response in the Tools folder.

I have found the option "combined respose" and I can only get it to work when a BLH is selected by zeroing the rear chamber. Aside from losing the chamber, the response is 180 OOP with direct.

Oops! I'm still a newb with Hornresp and referenced the wrong tool for a FLH, click on directivity/response and choose the desired axis.

Ahhh, that's better :)

If I build a 5000cm^2 mouth directly in a corner, is it fair to model another segment in hornresp of 5000 to 60000 conical, being the corner of the room itself?

If the flare rate stays the same and there are no big transitions, theoretically yes.
