Yeah, they are my own experiments so I am the only one that need to care. They are based on your earlier work, so I felt like writing and tell you what I am doing with your ideas. The drivers we use may be superior or inferior. As long as mine are the best I could possibly afford I can relax. I do love horns, and I can probably find quite a few errors in my signal path. If they are there the horns will amplify them for me so I can hear them properly.
They are not time aligned at all yet. Will start measuring after everything is in place. I guess that could attribute to harshness. Or it is the nature of these mere toys I try to listen to. 
I did use quotation mark for "injection channel", because it really isn't one. But I would like to pretend it is because it sound pretty nice when I try to use it as one. It will look a lot like yours when I am closer to finishing. For one thing I might recone it to a proper fullrange JBL E-120. I listen to a lot of guitar and a full range guitar speaker in the background would sound really nice. I tried the Celestion V30 but Celestion has outsourced everything to China.
About the open baffle, it is a little rediculous to have a high powered low frequency speaker from JBL with a Fs at 35Hz and not get much output under 200Hz. Seemingly cleaner mids but what it was best at is gone in thin air.
I will check the forum again for more clues on the injection channel. It is the only thing that does not seem that straight forward to me.
That and how to tune midbass horn back chambers. If back chambers are necessary. I will check. Rerurn to Romy the Cat's Site
