Have you tried searching their tech data library, particularly about the 2380? IIRC they have charts posted of the response with the driver/horn w/o EQ, then show after EQ, etc. and explain what is required.
Same site has 2404 data, they go up/down in level like a sine wave as freq. goes up, look at the chart...I would be inclined to "get as much milage" from your mid horn as possible, and x the 2404's in as high as you can.
The 2227's go higher than 500Hz easily, and you need that mid horn to not be operating down to it's lower cutoff where distortion will be higher, 600 to 800 is a "nicer" place to cross than down right at the horn cutoff. Sam
