I can't find a/the post(s) where you describe the advantages of using a 4 inch throat. Stereo-lab makes both 4 and 8 inch throat 140Hz horns but I don't think they could make an 8 to 4 inch adapter...

With Fane 8M you would not need an 8 to 4 inch adapter. It is normal it you use a direct radiator driver as a compression driver than the size of cone is larger than the size of throat, up to the point of course. Fane 8M is 8” but it has very wide skirt of outer suspension that makes it effectively 6.5” driver. The 6.5” loaded into 4” is about to be right ratio.

Also, would it be advisable to have the Fane cover a wider range, say 250-1000Hz in a more compact and less expensive 4 way installation?

Oh, sure. Fane is very fine to shoot all the way up, I used it up to 1000Hz for a while, if fact you can take it even much higher if you wish. It would all depends from how much front chamber you have and how much you stress it with back chamber. BTW, if you add to Fane a phase plug then you can suck out of it even more HF. Fane is very inductive and you will not be able to roll it off at high knee circulated by normal equations but you shell be able to tweak it…

Thanks. I thought I had read about the throat but I couldn't remember what I had read nor where. I won't experiment with the phase plug, though, it's way over my capabilities.
