Great. I'm OK with reflex stuff, really need a week free to sit down and learn the basics of horn simming. As to when.... smiley13

Mykey, why lrc is 100? the panel under the driver is 65...the total cab's depth is 75...am I missing something?

Why the Mickey sim is wrong:

The distance between driver diaphragm and event (LRC) can't be 100. Here is the schematic diagram of Hornresp:

And if you put 100, you shift delay and phase which create a gap above 100 Hz. On real horn, the LRC hasn't influence on this, but it will make a difference in hybrid horn.

Second error: There is no expansion from the first part of the horn. It's a duct ! There isnt't any need of measurement to see it just watch it:

So the first part of the horn is 56,4 * 14.2 = 800, and 800 is S1 and S2 !
