It is good on the lower knee but starts falling down a little too early on the upper for my intended bandwidth. It would be better to crossover from JBL m151 from 350hz with this horn I guess...

- 350Hz - true. I bought a few M151 at US$79ea shipped new when JBL had their "tent sale" - am glad there are drivers available with better bandwidth. Does the dirrectivity of a horn that size affect response much in the 500Hz region?

below is an on-axis outdoors graph of my Bruce Edgar 100Hz hypex horn with 2220H and response didn't seem to tilt upwards. Its throat and mouth
size are close to your horn but path length only about 51cm.

Are their any currently made cone drivers to make a good horn with 350Hz crossover point which will keep up dB wise with this type midbass horn?

-just thought about something - that old hornresp did not have the lossy Le modeling. My JBL M151 goes a bit higher in that model than 15p80Fe

Interesting. I will try and update it, I hope the new version can work via wine at a mac! So it applies here because of the large voice coil?
