The 1200fe is not a midcone; it's a woofer; using it enables a lower low entry frequency. I'm guessing the point of his diy experiment was to hear what that would sound like; that would be mine.
As for GT's comment regarding a 10" in the Project May build, two explanations have been offered already in this thread, one by me, one by Rob.

Hi Martin,
I don't see the necessity to consider exotic driver (which are now NLA anyway)
Consider this relatively cost effective arrangement which would go some way to mitigating the concerns:
Simple two way crossover at 500-600 hertz
Woofer - JBL 2234 or 150C fast hi sensitivity under hung driver
Horn - 3732. https://reconingspeakers.com/product...aveguide-3732/
Augmented bass from diy sub 2245/ 2269, W1500
Augmented HF from 2405, 2202
This is an excellent horn but above all is diy friendly.
I have chosen this configuration because with a long vertical array of drivers it can be difficult to obtain a coherent listening window.
I agree. However the manner in which those soa drivers to sing together in JBLs systems calls for some ownership on the part of user as to how they set up and listen to these systems.
I can personally draw on examples where I have auditioned these systems set up in inappropriate environments by the user(s) and listened to in contempt of the recommendations in the owner manuals. The user(s) end up blaming the design and the designer for getting it wrong and then attempts to re-configure the system in some way to improve the result. Whats's concerning is they think they are right. No joke. I won't repeat Greg's comments. We just let them continue to screw up the result so there are no arguments.
So when anyone says something contrary to the way Greg designed a system I take it with a grain of salt because they are "wrong" in one way or another.
If you are starting a diy-project do what ever pleases you.
Hello MartinGreat,have you ever tried any other 15'' wooofer and 10'' midrange cone combo?
Yes 2235/2122 2035/2122/2123 The E-145 is my favorite.
Rob
