A driver that could possibly be used to clone the AG horn: RCF MR8N301
Their spec sheet shows 107dB / watt* on a horn, bandwidth of ~500Hz to 3kHz.
Their horn is tiny (very short, 35*40cm mouth) for close spacing in arrays. An bigger horn (an AG sized mouth, but shorter) should extend the LF down to the driver's Fs (with -3dB just under 300Hz).
The RCF phase plug seems to be built for efficiency over bandwidth (like type 2 in the link). Type 1 or 3 from the link might extend the HF a little, but possibly not worth the effort as 3.5kHz looks like the most you'd ever get.
*when I model the raw driver (half space, as they measure in a "hemispherical" environment), I get the same 102dB efficiency at max, but I get less gain for the horn. Maybe I'm doing something wrong.
