It's pretty app-specific. You use a parallel cap/resistor combo to roll off the midband relative to the highs in a constant-directivity horn, which tends to have a "lump" response centered around 1-2k. So, you need to roll off the lump without throwing away the bottom end of the passband. I'll try to get a better version put together with 2nd order filter support (did some testing of this method tonight) and expanded displays (summed impedance, etc) later on this week.
