I'm playing a lot with F.A.S.T. project for a while, and i was wondering about the ''C.A.S.T.'' alternative, where the Fullrange driver is replaced by a Compression driver...
In my case, that would be hornless, as discussed in that thread

But of course one can use a short horn as well.
In both cases i think the use of an DSP/EQ is mandatory; massive gain adjustements will be needed, steep xover slope, EQing, etc...
I didnt try it yet, but i think it might work good. Not quite sure about the upper end though, because the only CD that are going low enough (400-500hz) are most of the time the larger 4'' diaphragms, and they might not be at their best @ 10khz+ but still, i think we can get something pretty decent on 9 octaves, with extraordinary undistorted potential SPL output
😱
Also, the less expensive option (and maybe a better sounding one?) would be to use a 3'' diaphragm (2'' throat) along with a subwoofer that still in his comfort zone around 700-800hz, like the TIW250XS or the 8W1v3...
Food for thoughts!
