One of the options you mentioned for the cornerhorns in the past was a 3 way system with a midrange direct radiator in the front, and a second midrange over top of the bass in the corner horn section.

I was curious if I could do a 400-3000 range this way (the PHL's do this and I think you've mentioned over 250 in the corner works as a direct radiator) and what kind of efficiency boost does the second driver in the horn give?

Thanks in advance.
