Nice build- if I may, a simple addition of a series inductor on the mid would likely smooth things out quite a bit- .5mH would probably be a good starting point.

Hello John W,
I see in post 14 of this thread that the crossover frequency between the 2119’s and 2404’s is near 4.2kHz.
JBL calls the 2119 a high power 2118. I cannot put my eyes on any data for the 2119. Will you tell us more about how you selected the crossover frequency and your impressions regarding the performance?
I am in the process of using 2118’s and hopefully 2404’s in a personal, compact 3-way, project.
All just for fun!

I kept the original 4628 crossover frequency for the 2118/2404. From what I read at the time, it was best to treat the 2119 the same as a 2118.
It seems like a fairly good range. You gain the advantages of the small horn and don't compromise too much in power handling. I don't think you should go much lower, and I'm not sure how much higher the 2118 will go before it begins to drop off on it's own.
